Re: [U-Boot] [PATCH v2] arm: fix a comment
Hi Masahiro, On Tue, 14 May 2013 10:43:07 +0900, Masahiro Yamada yamad...@jp.panasonic.com wrote: Changed for v2: - Fix one more comment I added one more comment line fixed at version 2. So, I am thinking the commit log should become arm: fix comments rather than arm: fix a comment Is it better to re-post my patch as version 3 with only commit log changed? Am I too worried about it?? You should try to read your commit message summary to yourself as if you did not know what the change is about, because that's what it is useful for: giving people a good idea of the change. If the summary tells everything except the actual source code change, that's good. A summary of arm: fix comments indicates two things about the change: explicitly, that it is about ARM; and implicitly, that it is cosmetic. But it does not say which part of U-Boot it applies to, even though this single file can be mentioned in a summary line. Readers will have to waste some time looking at the change content to find out. Plus, if it is cosmetic, then the fact that it is about ARM does not matter that much, does it? e.g., someone looking for ARM changes that might explain a weird behavior will most certainly not be interested in this change even though it is ARM. For instance, a cosmetic fix on ARM code could easily go in the mainline tree without going through the ARM tree first. So, I'd put cosmetic: first, but admittedly, that's a debatable point. So... how about a V3 with a commit summary of cosmetic: arm: fix comments in arch/arm/lib/crt0.S ? People reading the summary for no particular reason will know all there is to know except the detailed comment fixes; people looking for crt0 changes will see it, and so will people looking for ARM changes, but cosmetic: will help them move it aside in their search; cosmetic: helps deciding whether to apply the patch and to which tree; etc. I'm new here, and I'm not sure this kind of update is mandatory. I will appreciate any advice. No problem. Best Regards Masahiro Yamada Amicalement, -- Albert. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] [PATCH v2 0/4] Factorize ARM relocate_code instances
This series replaces all instances of relocate_code in various start.S files from the ARM architecture with a single instance in arch/arm/lib/relocate.S. This is done in steps, each step keeping the whole of ARM U-Boot buildable and runnable and touching as little code as necessary. 1. Drop mx31pdk SPL call to relocate_code In SPL of mx31pdk, board_init_f calls relocate_code to move SPL from the NAND read buffer to SRAM. This move is not a relocation and is thus better implemented as a simple ad hoc copy loop. 2. Drop tx25 SPL call to relocate_code Same as mx31pdk. 3. Prevent all SPLs from assembling relocate_code Now that no SPL uses relocate_code any more, remove it completely from SPL builds by putting it entirely between #ifndef CONFIG_SPL_BUILD and #endif preprocessor conditional. 4. Actual factorization of relocate_code Remove all instances of relocate_code from start.S and create a new file, arch/arm/lib/relocate.S, to provide the new single instance of relocate_code. The only non-trivial change is that for PXA25X, a call to unlock (actually disable) dcache is moved from before relocating to after relocating. As this cache is either locked-as-RAM or disabled, but never used as actual DDR cache, this move has no performance effect on relocation and no functional impact either. Changes in v2: - dropped relocate_code() call from mx31pdk SPL - dropped relocate_code() call from tx25 SPL - dropped all relocate_code instances from SPL builds - use ENTRY / ENDPROC macros - preserve PXA25X dcache unlocking Albert ARIBAUD (4): mx31pdk: copy SPL directly, not using relocate_code. tx25: copy SPL directly, not using relocate_code. arm: do not compile relocate_code() for SPL builds arm: factorize relocate_code routine arch/arm/cpu/arm1136/start.S | 81 --- arch/arm/cpu/arm1176/start.S | 77 - arch/arm/cpu/arm720t/start.S | 77 - arch/arm/cpu/arm920t/start.S | 77 - arch/arm/cpu/arm925t/start.S | 77 - arch/arm/cpu/arm926ejs/start.S| 81 --- arch/arm/cpu/arm946es/start.S | 77 - arch/arm/cpu/arm_intcm/start.S| 77 - arch/arm/cpu/armv7/start.S| 78 -- arch/arm/cpu/ixp/start.S | 77 - arch/arm/cpu/pxa/start.S | 96 +++- arch/arm/cpu/s3c44b0/start.S | 77 - arch/arm/cpu/sa1100/start.S | 77 - arch/arm/lib/Makefile |1 + arch/arm/lib/relocate.S | 111 + board/freescale/mx31pdk/mx31pdk.c | 16 +- board/karo/tx25/tx25.c| 16 +- 17 files changed, 151 insertions(+), 1022 deletions(-) create mode 100644 arch/arm/lib/relocate.S -- 1.7.10.4 ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Calculate reserved fields according to IFC bank count
1. Move csor_ext register behind csor register and fix res offset
2. move ifc bank count to config_mpc85xx.h to support 8 bank count
There's no IFC controller instead of eLBC controller on some platforms,
such as MPC8536, P2041, P3041, P4080 etc, so there's no macro definition
for the number of IFC chip select(CONFIG_SYS_FSL_IFC_BANK_COUNT) which
is used in the IFC controller header file fsl_ifc.h on these platforms.
This paragraph is pretty confusing. Is this just explaining that IFC_BANK_COUNT
isn't being defined for devices that don't use IFC? Or is it explaining why you
have to guard fsl_ifc.h with a #ifdef?
[Mingkai] Both. Some devices doesn't use IFC, thus, there's no IFC_BANK_COUNT
for these devices. While some common files include fsl_ifc.h, which needs
IFC_BANK_COUNT definition, that's the reason why I have to guard fsl_ifc.h. I
will change it to the following:
3. Guard fsl_ifc.h with CONFIG_FSL_IFC to eliminate the compile error on some
devices that doesn't have IFC controller.

There seem to be a large number of CONFIG options associated with each and
every new bank. It's following the pattern of the existing code, so I'll accept
it, but I can't help but think that some of these config options are entirely
redundant (would we ever have CSPR4, and *not* CSOR4?). This is, admittedly,
based only on a high-level view of the code -- I'm not familiar with the
specifics of the IFC design.
[...]
[Mingkai] These codes are redundant, we can factor this out in another separate
patch.

These aren't really config values. They are values derived from a CONFIG value,
and they only have local scope (so there's no need for the very global scoping
of the names).
Also... Are these correct? 0x25 is a strange amount of gap in register space.

Re: [U-Boot] [PATCH] OMAP5: Add support for the SOM5_EVB board (OMAP5430-based)
Hi Tom, I'm currently busy with other work; on the other hand, careful rebasing shall require some time, especially the Palmas stuff. What would be the deadline for a V2 submission? Meanwhile could you please have a look at the (already old) http://patchwork.ozlabs.org/patch/232743/? A simple patch, shall be needed if we enable USB (for the uEVM along with our board). In general, what are your plans regarding USB (.../patch/232742/)? And again on I2C (.../patch/233823/): what is you final opinion? I'm confident that this patch is a major improvement for OMAP4/5 at least. Please see some more comments inline below.

Add it to the most likely struct in the headers. The entire struct (I call it omap5_scrm_regs in theory, similar to the corresponding omap4_scrm_regs for OMAP4) is not defined anywhere. Of course I could define only the member that I need, but I guess it is a (responsible) TI job to define hardware descriptors. Or I'm wrong? Please advise.

[U-Boot] [PATCH v2 0/6] arm: mvf600: Add Freescale Vybrid MVF600 CPU and MVF600TWR board support
This series contain the support for Freescale Vybrid MVF600 CPU and MVF600TWR board. Vybird devices are built on an asymmetrical-multiprocessing architecture using ARM cores. The families in the Vybrid portfolio span entry-level, single core Cortex-A class SoCs all the way to dual heterogeneous core SoCs with multiple communication and connectivity options. Part of the Vybrid platform, MVF600 is a dual-core eMPU combining the ARM Cortex A5 and Cortex M4 cores. The u-boot runs on Cortex A5 core. MVF600 shares some IPs with i.MX family, such as FEC,ESDHC,WATCHDOG,I2C,ASRC and ESAI. MVF600 also shares some IPs with ColdFire family, such as eDMA and DSPI. MVF600 still has its own IPs, such as PIT,SAI,UART,QSPI and DCU.

[U-Boot] [PATCH v2 2/6] arm: mvf600: Add IOMUX support for Vybrid MVF600
This patch adds the IOMUX support for Vybrid MVF600 platform. There is a little difference for IOMUXC module between MVF600 and i.MX platform, the muxmode and pad configuration share one 32bit register on MVF600, but they are two independent registers on I.MX platform. A CONFIG_IOMUX_SHARE_CONFIG_REG was introduced to fit this difference.

[U-Boot] ARM v7: Flush icache when executing a program with go
Tom Rini wanted me to post this again. There is no change from previous
version.
I do agree with Wolfgang Denk that this really SHOULD NOT be arch
specific. The only reason why I made this ARMv7 specific is because
blindly calling invalidate_icache_all() from the go command will cause
loud complains on other arches where the icache is not
supported/enabled. The question is what is the correct solution
- Doing it arch specific like this (or other arch aproach?)
- Change invalidate_icache_all() to be silent if the icache is not
enabled/supported?
- Something else?
---
ARM v7 runs with icache enabled. For reliable results the go command
needs to flush the icache before jumping or it may risk running
cached instructions that differ from what currently is in memory.

Re: [U-Boot] [PATCH 03/21] fsl_ifc: add support for different IFC bank count
On May 14, 2013, at 3:59, Hu Mingkai-B21284
b21...@freescale.commailto:b21...@freescale.com wrote:
Hi Andy,
Please find my replies in line.
Thanks,
Mingkai
There's no IFC controller instead of eLBC controller on some platforms,
such as MPC8536, P2041, P3041, P4080 etc, so there's no macro definition
for the number of IFC chip select(CONFIG_SYS_FSL_IFC_BANK_COUNT) which
is used in the IFC controller header file fsl_ifc.h on these platforms.
This paragraph is pretty confusing. Is this just explaining that IFC_BANK_COUNT
isn't being defined for devices that don't use IFC? Or is it explaining why you
have to guard fsl_ifc.h with a #ifdef?
[Mingkai] Both. Some devices doesn’t use IFC, thus, there’s no IFC_BANK_COUNT
for these devices. While some common files include fsl_ifc.h, which needs
IFC_BANK_COUNT definition, that’s the reason why I have to guard fsl_ifc.h. I
will change it to the following:
3. Guard fsl_ifc.h with CONFIG_FSL_IFC to eliminate the compile error on some
devices that doesn’t have IFC controller.
That's good, thanks

These aren't really config values. They are values derived from a CONFIG value,
and they only have local scope (so there's no need for the very global scoping
of the names).
Also... Are these correct? 0x25 is a strange amount of gap in register space.
[Mingkai]They’re correct. I’ve test it on T4, C293QDS and P1010RDB platform
when I submitted this patch.
The value 0x25 is caused by the fact that the 0x25 is represents the length of
cspr (148 bytes) in unit 4 bytes.
Here is the magic math: 148 / 4 = 37 = 0x25
All that aside, I think we should just define the register offsets to cover all
existing (or even predicted) registers, and make the gap hard-coded as before.
There's no real advantage to specifying only as many as are implemented, and
this method seems ripe for potential bugs in the future.
[Mingkai] I modified the code as follows,
First define the different register space length in bytes as follows:
#define IFC_CSPR_REG_LEN148
#define IFC_AMASK_REG_LEN 140
#define IFC_CSOR_REG_LEN140
#define IFC_FTIM_REG_LEN576
Then in the struct, use the register space length minus the actual used space
and get the reserved space as the red line indicates.
struct fsl_ifc {
u32 ifc_rev;
u32 res1[0x2];
struct {
u32 cspr_ext;
u32 cspr;
u32 res2;
} cspr_cs[CONFIG_SYS_FSL_IFC_BANK_COUNT];
u32 res3[IFC_CSPR_REG_LEN - sizeof(cspr_cs)];
That's a bit clearer. However, it needs to be u8 if you are going to specify
bytes.
struct {
u32 amask;
u32 res4[0x2];
} amask_cs[CONFIG_SYS_FSL_IFC_BANK_COUNT];
u32 res5[IFC_AMASK_REG_LEN - sizeof(amask_cs)];
struct {
u32 csor;
u32 csor_ext;
u32 res6;
} csor_cs[CONFIG_SYS_FSL_IFC_BANK_COUNT];
u32 res7[IFC_CSOR_REG_LEN - sizeof(csor_cs)];
struct {
u32 ftim[4];
u32 res8[0x8];
} ftim_cs[CONFIG_SYS_FSL_IFC_BANK_COUNT];
u32 res9[IFC_FTIM_REG_LEN - sizeof(ftim_cs)];
}
BTW, the patch can’t be applied to your mpc85xx public tree cleanly, so if you
think this modification is ok, I will submit a new patch based on the latest
git tree base.
Ok, thanks!

[U-Boot] Wrong RAM Size on Devkit8000
Hi, I'm currently testing u-boot 2013.04 with SPL on a Devkit8000 with 256MB of RAM. Trouble is, it only detects 128MB of RAM. The x-loader found on the NAND detects 256MB and works perfectly with it. I obviously tried to change the mcfg field of the timings structure to be at MICRON_V_MCFG_165(256 20), however, while it obviously detects 256MB of RAM, it then crashes quite badly when booting to a userspace (and actually using that much RAM I guess).

Re: [U-Boot] fatwrite problem
Hi Tom,
It has become a bit quiet on this thread, but I just made the changes as I
suggested, including some other fixes. Here is what I did:
Added a check for blkcnt 0 in mmc_write_blocks (drivers/mmc.c). By doing
this in the lowest level function, it also solves a hangup if for instance an
mmc write command is given with a block count being 0.
Solved a checksum issue in fs/fat/fat.c. The mkcksum has const char arguments
with a size specifier, like const char name[8]. In the function, it is
assumed that sizeof(name) will have the value 8, but this is not the case (at
least not for the compiler I use and I guess not according to ANSI C). This
causes long filename checksum errors for each fat file listed or written.
Made some changes to fs/fat/fat_write.c. Fixed testing fat_val for
0x/0xfff8 and 0xfff/0xff8 by adding the corresponding fatsize in
the test (as I read in earlier posts) and some changes in debug output.
I have used this for a few weeks now without any mmc and fat related problems
sofar.
I do have a patch file for this. Should I post this with a Signed-off-by (etc,
etc), or would you like to receive and review this patch file yourself first?

Ruud

Onderwerp: RE: [U-Boot] fatwrite problem
Hi Everyone,
As far as I noticed, set_cluster can be called quite often with a size being
zero. That can indeed be with a file that has a size being an exact multiple
(including 0) of the clustersize, but also for files that are smaller than the
size of one cluster. In that case, the 1st call to set_cluster has a size being
zero:
fatwrite mmc 0:1 4200 test3 200
writing test3
set_cluster; clustnum: 1487, startsect: 6104, size 0
set_cluster; clustnum: 1487, startsect: 6104, size 512
set_cluster; clustnum: -6, startsect: 132, size 2048
512 bytes written
This was solved by adding the if(size) in set_cluster (otherwise the above
test would fail). However: this does not solve all the problems. If I tried to
write a file of 16 bytes, I still got an error. Looking closer at set_cluster,
the 1st call to disk_write( ) has a size being size / mydata-sect_size. This
would mean that for any file (or file remainder) smaller than the sector size
(typicaly 512 bytes), the fatwrite would fail.
So to my opinion, the actual cause of the problem is in the function
disk_write( ), that can't be called with a size being zero. That could be
solved by adding tests before calling set_cluster and/or before calling
disk_write from set_cluster, but the safest (and simplest) would be to add this
piece of code to disk_write:
if(nr_blocks == 0) {
return 0;
}
With this change I have been able to write various file sizes so far without
problems (512 bytes, 2048, 2049, 16, 0).
Another option would be to solve this in the cur_dev-block_write function,
being mmc_bwrite( ) for the mmc device. Since his has a do { } while, it will
always call mmc_write_blocks() even if blkcnt equals zero. Maybe even the
mmc_write_blocks would be the best place to fix this...
I will do some further testing here. Meanwhile, please let me know if this
change would make sense to you, and what would be the best place to put it.
Probably the lowest level function, if you would ask me.
Also I would like to know if it would not cause any oher problems according to
your knowledge.

Ruud

There is at least one non-EHCI compliant controller (i.e. Faraday

Futhermore, it not only leave reserved and CONFIGFLAG registers

And thus, we need weak-aliased functions to both TDI stuff
and PORTSC registers for interface abstraction.

Sorry, but I'll prefer 'int' over 'unsigned short', since it looks to me

a 'port = -1' to be passed to ehci_get_portsc_register().
And I think '-1' is a better self-explain value, so I'd like to stick
with 'int'
Sure, but then the comparison is signed, not unsigned. Besides, it's
unnecessary change to the logic of the code. Or did I miss something ?
1. There is a bug in ehci_submit_root() of usb ehci:
int ehci_submit_root()
{
..
if (port CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS) {
printf(The request port(%d) is not configured\n, port - 1);
return -1;
}
status_reg = (uint32_t *)ctrl-hcor-or_portsc[port - 1];
..
}
The 'port' is actually a '0' at start-up, so we actually accessed
a wrong register.
But fortunately the wrong register actually points to CONFIGFLAG(0x40)
with a safe value for the following codes.
2. One of Vivek Gautam's usb patches has altered the logic of usb host
upon launching 'usb start', if we report a error upon (port - 1 0),
the current u-boot usb would failed to scan ports. (At least it
failed at Faraday platforms.)
However it looks to me that it's o.k to report a error upon (port
- 1 0) at old usb ehci stack.
(i.e. 10 days ago, in master branch of u-boot)
And thus I add a quick check to PATCH v7.
__weak uint32_t *ehci_get_portsc_register(struct ehci_hcor *hcor, int port)
{
/*
* The u-boot would somehow set port=-1 at usb start-up,
* so this quick fix is necessary.
*/
if (port 0)
port = 0;
Maybe we should return fail, no ? Can you pinpoint where does the req-index
(resp. port) get set to -1 ? And which commit introduced this breakage ?

Marek Vasut

OK, that's fine.
Since _end is linker-generated contrary to the other symbols that you use in
those asm lines, have you checked that no R_ARM_ABS32 relocation data is
generated here? OTOH, -pie is not used with SPL, so there should be no

Before finding your patch, I was thinking another way to fix this problem. My idea is to just use 'get_unaligned' and 'put_unaligned' functions instead of introducing special macros. With this way, we don't need to change the fields of struct cfi_qry. I think we should make sure to use natural alignment as much as possible, really. I'm keeping Albert in CC because this is his turf. Marek, you invoked me; next time be careful what you wish for. :) My rules (not 'of thumb', as they also apply to ARM) regarding alignment are as follows (yes, it's a more general answer than your question called for, but the last rules are more directly related): 0) Never assume that U-Boot can use native unaligned accesses. Yes, ARMv7+ can do native unaligned accesses with almost no performance cost, but U-Boot runs on all sorts of targets (not only ARM), some allowing unaligned access but with a penalty, and some unable to perform unaligned access at all. We always run the risk that some code in U-Boot ends up running on target which will die horribly on some unaligned access, so to avoid this we must assume and enforce strict alignment, even for architectures which do not require it, such as ARMv7+. 1) As per rule 0, always enable alignment check -- again, even on targets which could do without it. This allows catching any unaligned access, be they accidental (bad pointer arithmetic) or by design (misaligned field in an otherwise aligned struct). 2) Despite rules 0 and 1, always enable native unaligned accesses (IOW, always use option -munaligned-accesses). That is because without this option (or more precisely, when -mno-unaligned-accesses is in effect), the ARM compiler may silently detect misaligned accesses and fix them using smaller aligned accesses, thus hiding a potential alignment issue until it bites on some later and unrelated target run. 3) always size fields in a structure to their natural size, i.e., if a field is 16-bits, make it u16 or s16. 4) always align fields in a structure to their natural boundaries, i.e., if a field is 16-bits, align it to an even address. 5) if a field absolutely has to be unaligned because of hardware or standard, then a) document that! and b) access it with explicit unaligned access macros. So in essence, I am opposed to changing fields from 16-bit to 2 x 8-bit just 'because unaligned'. Either fix the fields' alignment, if at all possible; and if not, then apply rule 5: document the issue and fix it using explicit unaligned access macros. Best regards, Marek Vasut Amicalement, -- Albert. Thank you for your review and the very useful list of rules. Although theoretically the cfi_qry structure can be made non-packed and with properly aligned members (and filled in by individual members assignments when reading, rather than just copying byte-to-byte, as it is now), it may make more sense to keep it packed and replicating the actual flash layout as much as possible. This also makes it more similar to what is used in Linux kernel (although it seems to rely on native unaligned access ;-)). So, it seems reasonable to choose to apply rule 5: add comments to cfi_qry strcuture definition and use get_unaligned/put_unaligned for the necessary fields (only for really unaligned members, since some 16-bit fields are properly aligned). I'm sending the version 2 of the patch with this change as a separate message with Subject: [U-Boot][PATCH v2] cfi_flash: Fix unaligned accesses to cfi_qry structure Please, let me know if somebody still prefers making non-packed aligned structure, as described above.

[U-Boot] [PATCH] tegra: always build u-boot-nodtb-tegra.bin
From: Stephen Warren swar...@nvidia.com
Even when eventually building u-boot-dtb-tegra.bin, separately building
u-boot-nodtb-tegra.bin can be useful, since building it encapsulates the
SPL padding step. If you want to tweak u-boot.dtb and regenerate
u-boot-dtb-tegra.bin, it is then a simple cat operation.

[U-Boot] [PATCH] fdt: allow bootdelay to be specified via device tree
From: Stephen Warren swar...@nvidia.com This can be useful to force bootcmd to execute as soon as U-Boot has started. My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with an image to be written to device boot flash, with the DT config property bootcmd set to contain a command to write that image to flash. In this scenario, we don't want to allow any stale bootdelay value taken from the current flash content to affect how long it takes before the flashing process starts.

Why not __image_copy_start/end instead? I know that the result will be the

here, but the naming would be more appropriate. The existing
u-boot-spl.lds
still gives access to __image_copy_*.
Well, yes, the naming seems appropriate, and I thought and said so
myself some time ago. But then, I realize that __image_copy_start and
__image_copy_end are tightly coupled with relocation, and I want to
avoid creating any additional ties between relocation and SPL just when
I am severing them. IOW, I want to keep the option of having a reduced
SPL linker file, distinct from the u-boot one, and where none of
__image_copy_*, __rel_dyn_* or __dynsym_start exist.
OK, that's fine.
Since _end is linker-generated contrary to the other symbols that you use in
those asm lines, have you checked that no R_ARM_ABS32 relocation data is
generated here? OTOH, -pie is not used with SPL, so there should be no
relocation data at all generated here, and the true final addresses should be
in
the binary image.
Indeed, SPL is meant to be loaded at its link-time address -- or, in the
case of mx31pdk and tx25, loaded in a read buffer then moved by itself
to its link-time address. In no case is SPL supposed to be relocated.
You can verify with readelf -r that no relocation records are generated
for SPL builds.

Benoît

Re: [U-Boot] [PATCH] OMAP5: Add support for the SOM5_EVB board (OMAP5430-based)

A simple patch, shall be needed if we enable USB (for the uEVM along with our board). In general, what are your plans regarding USB (.../patch/232742/)? Thanks for the reminder, I'll grab 232743 soon. 232742 looks OK, but do you have a patch around for uEVM still? Not yet (didn't have the opportunity to test, although some uEVMs should be around at MMS). As you know, a patch shall be needed in the uEVM board file along with the common USB stuff. Yeah, I can test it as well if you write it up, and may find the time if you point me in the right direction. OK, shall do it. And again on I2C (.../patch/233823/): what is you final opinion? I'm confident that this patch is a major improvement for OMAP4/5 at least. I'm inclined to go with it, just need to mentally unswap the i2c notes in my brain and think it over one more time. Just applied 233823 to current u-boot-ti master. Works fine. OK, thanks. Just to avoid confusion: I applied it and tested on a locally cloned version of u-boot-ti, not upstream (don't laugh please; just want to clarify for those who don't know that it is your job). [snip] Currently the scrm struct is defined for OMAP4 in the asm/arch-omap4/clocks.h file and I have already done the same for OMAP5 by analogy. I must admit however that this approach does not correspond to the latest way by which groups of OMAP hardware regs are defined, prcm in particular - a struct in omap_common.h, holding only the required regs, no padding and such garbage, and an init with the physical addresses in a .c file for the particular SoC (prcm-regs.c). But still the Panda board, for example, uses the old way for scrm. Therefore I did it the same for OMAP5, which was easier (I'm old and lazy ;) ). Yes, I'm OK starting off with moving things into omap_common.h as-is and then updating them a bit later ala pcrm-regs.c. Who is starting off, me or you? ;) -- Tom BR, Lubo ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

The patch set is divided into the four following sections: [...] What's the state of this? I tried applying your patch series on top of current master and getting it to work on a CuBox Pro (2GiB SDRAM instead of 1GiB), but with no success so far. I changed kwbimage.cfg to match dramregs_cubox_2gb.txt in Rabeeh's tree and fixed arch/arm/cpu/armv7/dove/timer.c to work with the generic global_data (introduced by baa1e53 and 50b1fa3). However there seems to be something else missing or broken as there's no output whatsoever on the serial console after booting the new image via UART. The same boot procedure works fine with an image built using Rabeeh's tree.

[U-Boot] [PATCH 0/5] Optimize ARM relocation
*** NOTE: this series applies over the 'Factorize
ARM relocate_code instances' series.
This series optimizes relocation by ensuring ARM
binaries only use one type of relocation record,
R_ARM_RELATIVE., then optimizing relocation code
accordingly.
The only known case where relocation records other
than R_ARM_RELATIVE are generated is when a reference
is made to a symbol defined in the linker script, e.g.
__image_copy_start, __image_copy_end, __rel_dyn_start,
__rel_dyn_end, and __dynsym_start.
Moving the definition of these symbols from the linker
scripts into a C module causes their references' types
to become R_ARM_RELATIVE.
First, arch/arm/lib/bss.c is replaced by a more generic
arch/arm/lib/sections.c where all section symbols will
be defined.
Second, __image_copy_start and __image_copy_end symbols
are moved from linker scripts to arch/arm/lib/sections.c
Third, __rel_dyn_start, __rel_dyn_end and __synsym_start
are moved from linker scripts into arch/arm/lib/sections.c
Fourth, a check is added to the build system to ensure
that ELF U-Boot binaries only use R_ARM_RELATIVE records.
Last, relocate_code is optimized
Albert ARIBAUD (5):
arm: generalize lib/bss.c into lib/sections.c
arm: make __image_copy_{start,end} compiler-generated
arm: make relocation symbols compiler-generated
arm: ensure u-boot only uses relative relocations

File arch/arm/lib/bss.c was initially defined for BSS only,
but is now going to also contain definitions for other
section-boundary-related symbols, so rename it for better
accuracy.
Also, remove useless 'used' attributes.

Re: [U-Boot] [PATCH 0/5] Optimize ARM relocation
On Tue, 14 May 2013 22:02:55 +0200, Albert ARIBAUD albert.u.b...@aribaud.net wrote: *** NOTE: this series applies over the 'Factorize ARM relocate_code instances' series. This series optimizes relocation by ensuring ARM binaries only use one type of relocation record, R_ARM_RELATIVE., then optimizing relocation code accordingly. The only known case where relocation records other than R_ARM_RELATIVE are generated is when a reference is made to a symbol defined in the linker script, e.g. __image_copy_start, __image_copy_end, __rel_dyn_start, __rel_dyn_end, and __dynsym_start. Moving the definition of these symbols from the linker scripts into a C module causes their references' types to become R_ARM_RELATIVE. First, arch/arm/lib/bss.c is replaced by a more generic arch/arm/lib/sections.c where all section symbols will be defined. Second, __image_copy_start and __image_copy_end symbols are moved from linker scripts to arch/arm/lib/sections.c Third, __rel_dyn_start, __rel_dyn_end and __synsym_start are moved from linker scripts into arch/arm/lib/sections.c Fourth, a check is added to the build system to ensure that ELF U-Boot binaries only use R_ARM_RELATIVE records. Last, relocate_code is optimized Hmm, it seems I need to see my work posted on the list to discover how I could have done it better... I just noticed that if ARM binaries only have R_ARM_RELATIVE record types, then all the .dynsym sections can actually be dropped from the binaries. So, if I reorder the series and put patch 5/5 first, then I can eliminate patch 3/5, or more to the point, replace it with one which eliminates all dynsym stuff from linker scripts, further reducing code size. That'll go in V2... Amicalement, -- Albert. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Not yet (didn't have the opportunity to test, although some uEVMs should be around at MMS). As you know, a patch shall be needed in the uEVM board file along with the common USB stuff. Yeah, I can test it as well if you write it up, and may find the time if you point me in the right direction. OK, shall do it. Thanks! [snip] [snip] Currently the scrm struct is defined for OMAP4 in the asm/arch-omap4/clocks.h file and I have already done the same for OMAP5 by analogy. I must admit however that this approach does not correspond to the latest way by which groups of OMAP hardware regs are defined, prcm in particular - a struct in omap_common.h, holding only the required regs, no padding and such garbage, and an init with the physical addresses in a .c file for the particular SoC (prcm-regs.c). But still the Panda board, for example, uses the old way for scrm. Therefore I did it the same for OMAP5, which was easier (I'm old and lazy ;) ). Yes, I'm OK starting off with moving things into omap_common.h as-is and then updating them a bit later ala pcrm-regs.c. Who is starting off, me or you? ;) Since your series needs it (so we aren't writing to magic locations which isn't allowed), you please.

I think you are saying to do the rearrangement and clean-up first, then add autoconf afterwards. I can do that but really I am wondering what you think of the autoconf concept? The Kconfig stuff is related here too, but first I would like to decide on what to do with the #ifdefs. I think a lot of our #ifdefery is a problem of code that's in need of some love and re-org and cleaning and updating. One of the old style rules I still try and follow is that after a few levels of indent code doesn't read well. Also big nested #ifdefs don't read well. So we're trading one in for the other. But your series showed a lot of places where we can re-factor things to improve readability. So lets go that way. Then we can see if there's still things to improve on, and what dead code we still have around. So are you saying that you are keen on the autoconf idea? I'm saying lets clean up the code and see if we still need something like autoconf. It seems to provide the most benefit in terms of readability in places that could read a lot better with some clean up and refactoring before we add new tools to the pile. Yet another great advantage of autoconf is that it ensures a consistent combination of the configuration options, with the status quo it is so easy to make a mistake and create a deficient configuration. --vb -- Tom ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

+U-Boot for the Congatec Conga-QEVAl Evaluation Carrier board
+
+This file contains information for the port of U-Boot to the Congatec
+Conga-QEVAl Evaluation Carrier board.
+
+1. Boot source, boot from SD card
+-
+
+This version of u-boot works only on the SD card. By default, the
+Congatec board can boot only from the SPI-NOR.
+But, with the u-boot version provided with the board you can write boot
+registers to force the board to reboot and boot from the SD slot. If
+bmode command is not available from your pre-installed u-boot, these
+instruction will produce the same effect:
+
+conga-QMX6 U-Boot mw.l 0x20d8040 0x3850
+conga-QMX6 U-Boot mw.l 0x020d8044 0x1000
+conga-QMX6 U-Boot reset
+resetting ...
+
+The the board will reboot and, if you burnt your SD correctly the
+board will use u-boot that live into the SD
..., if you have written your SD correctly ...
+To copy the resulting u-boot.imx to the SD card:
+
+ sudo dd if=u-boot.imx of=/dev/xxx bs=512 seek=2sudo sync
I'd not add 'sudo' prefix. Some people may run it as root already or
have given rights to write to the block device. Please remove the '
sudo sync' from it as well.
+Note: Replace xxx with the device representing the SD card in your system.

This series optimizes relocation by ensuring ARM binaries only use one type of relocation record, R_ARM_RELATIVE., then optimizing relocation code accordingly. The only known case where relocation records other than R_ARM_RELATIVE are generated is when a reference is made to a symbol defined in the linker script, e.g. __image_copy_start, __image_copy_end, __rel_dyn_start, __rel_dyn_end, and __dynsym_start. Moving the definition of these symbols from the linker scripts into a C module causes their references' types to become R_ARM_RELATIVE. First, arch/arm/lib/bss.c is replaced by a more generic arch/arm/lib/sections.c where all section symbols will be defined. Second, __image_copy_start and __image_copy_end symbols are moved from linker scripts to arch/arm/lib/sections.c Third, __rel_dyn_start, __rel_dyn_end and __synsym_start are moved from linker scripts into arch/arm/lib/sections.c Fourth, a check is added to the build system to ensure that ELF U-Boot binaries only use R_ARM_RELATIVE records. Last, relocate_code is optimized Hmm, it seems I need to see my work posted on the list to discover how I could have done it better... I just noticed that if ARM binaries only have R_ARM_RELATIVE record types, then all the .dynsym sections can actually be dropped from the binaries. So, if I reorder the series and put patch 5/5 first, then I can eliminate patch 3/5, or more to the point, replace it with one which eliminates all dynsym stuff from linker scripts, further reducing code size. That'll go in V2... Indeed. Best regards, Benoît ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Dear Kuo-Jung Su,
From: Kuo-Jung Su dant...@faraday-tech.com
There is at least one non-EHCI compliant controller (i.e. Faraday
EHCI) known to implement a non-standard TDI stuff.
Futhermore, it not only leave reserved and CONFIGFLAG registers
un-implemented but also has their address spaces removed.
And thus, we need weak-aliased functions to both TDI stuff
and PORTSC registers for interface abstraction.

What happens here if req-index is zero ?
Hint: the above code always does unsigned comparison ...
I think you should make the second argument of
ehci_get_portsc_register() unsigned short too (as is req-index in
struct devrequest).
Sorry, but I'll prefer 'int' over 'unsigned short', since it looks to me
that the u-boot would set 'req-index' to 0 at startup, which results in
a 'port = -1' to be passed to ehci_get_portsc_register().
And I think '-1' is a better self-explain value, so I'd like to stick
with 'int'
Sure, but then the comparison is signed, not unsigned. Besides, it's
unnecessary change to the logic of the code. Or did I miss something ?
1. There is a bug in ehci_submit_root() of usb ehci:
int ehci_submit_root()
{
..
if (port CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS) {
printf(The request port(%d) is not configured\n, port - 1);
return -1;
}
status_reg = (uint32_t *)ctrl-hcor-or_portsc[port - 1];
..
}
The 'port' is actually a '0' at start-up, so we actually accessed
a wrong register.
But fortunately the wrong register actually points to CONFIGFLAG(0x40)
with a safe value for the following codes.
2. One of Vivek Gautam's usb patches has altered the logic of usb host
upon launching 'usb start', if we report a error upon (port - 1 0),
the current u-boot usb would failed to scan ports. (At least it
failed at Faraday platforms.)
However it looks to me that it's o.k to report a error upon (port
- 1 0) at old usb ehci stack.
(i.e. 10 days ago, in master branch of u-boot)
And thus I add a quick check to PATCH v7.
__weak uint32_t *ehci_get_portsc_register(struct ehci_hcor *hcor, int port)
{
/*
* The u-boot would somehow set port=-1 at usb start-up,
* so this quick fix is necessary.
*/
if (port 0)
port = 0;
Maybe we should return fail, no ?
No, it would make the 'usb start' to terminate immediately,
and results in a port scan failure to at least Faraday EHCI.
Can you pinpoint where does the req-index
(resp. port) get set to -1 ?
Later I'll try to find out where we have 'req-index' set as a '0' in
'usb start'.
And which commit introduced this breakage ?
I believe it's there long ago, we just fortunately bypass the error at old day,
and now one of Vivek Gautam's USB patch make us face up to this issue.

Marek Vasut

un-implemented but also has their address spaces removed.
And thus, we need weak-aliased functions to both TDI stuff
and PORTSC registers for interface abstraction.

Changes for v6:
- Simplify weak aliased function declaration
- Drop redundant line feed
Changes for v5:
- Split up from Faraday EHCI patch
Changes for v2 - v4:
- See 'usb: ehci: add Faraday USB 2.0 EHCI support'

btw you can remove those braces around (1) and (0) below. But I
have one more question ...
Got it, thanks

What happens here if req-index is zero ?
Hint: the above code always does unsigned comparison ...
I think you should make the second argument of
ehci_get_portsc_register() unsigned short too (as is req-index in
struct devrequest).
Sorry, but I'll prefer 'int' over 'unsigned short', since it looks
to me that the u-boot would set 'req-index' to 0 at startup, which
results in a 'port = -1' to be passed to
ehci_get_portsc_register().
And I think '-1' is a better self-explain value, so I'd like to
stick with 'int'
Sure, but then the comparison is signed, not unsigned. Besides, it's
unnecessary change to the logic of the code. Or did I miss something
?
1. There is a bug in ehci_submit_root() of usb ehci:
int ehci_submit_root()
{
..
if (port CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS) {
printf(The request port(%d) is not configured\n, port -
1); return -1;
}
status_reg = (uint32_t *)ctrl-hcor-or_portsc[port - 1];
..
}
The 'port' is actually a '0' at start-up, so we actually accessed
a wrong register.
But fortunately the wrong register actually points to
CONFIGFLAG(0x40)
with a safe value for the following codes.
2. One of Vivek Gautam's usb patches has altered the logic of usb host
upon launching 'usb start', if we report a error upon (port - 1
0), the current u-boot usb would failed to scan ports. (At least
it
failed at Faraday platforms.)
However it looks to me that it's o.k to report a error upon (port
- 1 0) at old usb ehci stack.
(i.e. 10 days ago, in master branch of u-boot)
And thus I add a quick check to PATCH v7.
__weak uint32_t *ehci_get_portsc_register(struct ehci_hcor *hcor, int
port) {
/*
* The u-boot would somehow set port=-1 at usb start-up,
* so this quick fix is necessary.
*/
if (port 0)
port = 0;
Maybe we should return fail, no ?
No, it would make the 'usb start' to terminate immediately,
and results in a port scan failure to at least Faraday EHCI.
Can you pinpoint where does the req-index
(resp. port) get set to -1 ?
Later I'll try to find out where we have 'req-index' set as a '0' in
'usb start'.
It's from usb_new_device() -- usb_get_descriptor(), and thus
it's definitely correct to set index = 0 right here.
The only problem is 'We shall not always report an portsc error for
all request!'
