[U-Boot] [PATCHv3] pca953x: support 16-pin devices
This adds support for for the PCA9535/PCA9539 family of gpio devices which
have 16 output pins.
To let the driver know which devices are 16-pin it is necessary to define
CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to
create an array of {chip, ngpio} tuples that are used to determine the
width of a particular chip. For backwards compatibility it is assumed that
any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.

Changes since v2:
- I've addressed Peters style comments.

If the is removed, and if later val is set to non-zero before reaching this instruction, it will cause a bug. IOW, the makes the statement more resilient. If val really is zero then the result will always be zero :( Simply removing the would give a different result. It would be better to remove the whole bloody line ;-) I haven't followed this thread but I suspect the original code was wrong. Good point as to the removal if the removal must be done :) I still think that the original is functionally more correct *if we are not sure that val will always be zero. The earlier code was using read-modify-write strategy for mfpr programming. It is changed to create-write.

Re: [U-Boot] can't build u-boot-2010.12-rc2 for at91rm9200ek
Dear zzs213,
Am 09.12.2010 09:39, schrieb zzs213:
I just clone the git repos. and build at91rm9200ek with eldk4.1,the error
message is same.
Ok, so ELDK 4.1 is not working. How about ELDK 4.2, CodeSourcery
2009q{1,3}, 2010q1, 2010.09?
I change start.S let it check whether the main osc of at91rm9200 is work, So
I know need relocate the code or not. Use this method I boot u-boot in NOR
flash successful
So you added some at91 related stuff to arm920t/cpu/start.S to
conditionally branch to lowlevel_init()? You check if the
CKGR_MOR.MOSCEN is set or not and decide whether you branch to
lowlevel_init() or not.
I guess this is wrong.
First, if your u-boot is started from SDRAM you need correct initialised
clocks (main oscillator or not, you know you can leave the main
oscillator disabled and bypass it!), CS0 timing and SDRAM. In that case
you need to compile your u-boot with CONFIG_SKIP_LOWLEVEL_INIT and
therefore we do never branch to lowlevel_init() cause it just do not exist.
If you boot from NOR flash (BMS set to low during reset) the internal
ROM code is never executed and you need to switch on and configure the
clocks, setup CS0 timing and SDRAM configuration. This is done in
lowlevel_init() and therefore we do not set CONFIG_SKIP_LOWLEVEL_INIT in
that case. That case is currently broken in head of u-boot-arm/master
(not in u-boot/master currently, but will for v2010.12)!
You may use the board in some way suggested by atmel in some of their
documents. In that case you do have a preloader in NOR flash followed by
an u-boot blob. But that is also the first case! Your u-boot will be
copied to SDRAM by preloader!
- set CONFIG_SKIP_LOWLEVEL_INIT, set another CONFIG_TEXT_BASE cause.
You may use the at91rm9200ek_ram_config and set the target address of
your preloader copy to 0x2010. In that case NOR flash booting is
supported! But it is _not_ the case I meant with 'NOR flash booting does
not work a.t.m.'.
In any case you need to relocate if your CONFIG_TEXT_BASE is not set to
the location of u-boot at the end of board_init_f()! You can not know
the location in any case cause this can be influenced by some
environment variables. Therefore it is completely wrong to decide on the
setting of CKGR_MOR.MOSCEN if we need relocation or not.

Re: [U-Boot] [PATCH v2] davinci: Rewrite timer.c to use tbl/tbu emulation variables in gd
On 09/12/10 09:32, Nick Thompson wrote: This change allows the davinci timer functions to be used before relocation since it avoids using static variables prior to BSS being made available. The code is based on that used in the at91 timers, modified to use a davinci specific hardware timer.

Re: [U-Boot] [PATCH 3/4] arm920t: fix linker skript for -pie linking
Dear Albert ARIBAUD, In message 4d008638.4060...@aribaud.net you wrote: This patch is not needed, if no undefined weak symbol is available. This patch adds .plt/.rel.plt section which has R_ARM_JUMP_SLOT which is not handled in code. Therefore we do not really know what this patch does to the code, it was mostly a patch to handle the linker segfault described several times. Thanks for pointing this out. My bad: I did not relate the two series when going through patchwork. Wolfgang, I was about to send out a revert but after pulling u-boot.git and u-boot-arm.git I don't see Andreas' patch in there. If you haven't committed it yet, maybe you can fix this yourself? Hm... strange... I am absolutely sure that I did apply these patches last night, and then I even pushed them out... ... but now I see no trace of this either. Don't know what happened (I should learn this lesson - this is what I get when _not_ having a beer ;-) Ummm... now I have a problem, because I have marked all these patches as applied, both in patchwork and in my mail reader.

Re: [U-Boot] hwmon init
Hello Heiko, Is there a reason why the dtt sensors are initialized and accessed on u-boot startup? Historical reasons? The U-Boot Design Principles[1] clearly say: Initialize devices only when they are needed within U-Boot, i.e. don't initialize the Ethernet interface(s) unless U-Boot performs a download over Ethernet; don't initialize any IDE or USB devices unless U-Boot actually tries to load files from these, etc. (and don't forget to shut down these devices after using them - otherwise nasty things may happen when you try to boot your OS). Should that be changed? Yes indeed, the current situation is not consistent with the design principles and thus should be changed. Patches welcome! Best wishes Detlev -- LISP is the most powerful programming language, and if you want an inter- preter, LISP is the best. None of the other languages come anywhere near LISP in their power. The most exciting things about LISP are read, eval, and print. If you look at other languages, they have no equivalent for any of those. -- Richard Stallman -- DENX Software Engineering GmbH, MD: Wolfgang Denk Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-40 Fax: (+49)-8142-66989-80 Email: d...@denx.de ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
[U-Boot] [STATUS] next rebased / ARM help needed / release delayed
Hello, here is some news. Not exactly good news it seems: 1) I had to rebase the next branch to remove a commit which incorrectly changed behaviour of some commands. 2) By some stupid accident I lost track of some / most / all ARM related patches that are supposed to go into the current release and/or next; unfortunately I also maked these as applied' in patchwork. If you have any outstanding ARM patches that should go in, please drop me a note (ideally including the respective link into patchwork). Thanks, and sorry again. 3) We will have a delay in the release. I will try to get a -rc3 out by the weekend; new target for 2010.12 is December 20 (but don't hold your breath).

[U-Boot] [PATCH v4 2/7] [REV-1] gpio: Add Multi-Function-Pin configuration driver for Marvell SoCs
Most of the Marvell SoCs has Multi Function Pin (MFP) configuration registers
For ex. ARMADA100.
These registers are programmed to expose the specific functionality
associated with respective SoC Pins
This driver provides configuration APIs,
using them, configuration need to be done in board specific code
for ex- following code configures MFPs 107 and 108 for UART_TX/RX functionality
int board_early_init_f(void)
{
u32 mfp_cfg[] = {
/* Console on UART1 */
MFP107_UART1_RXD,
MFP108_UART1_TXD,
MFP_EOC /*End of configureation*/
};
/* configure MFP's */
mfp_config(mfp_cfg);
return 0;
}
Signed-off-by: Prafulla Wadaskar prafu...@marvell.com
---
Changelog v4:
1. Driver renamed as mvmfp
2. Re-architected mvmfp driver as per review feedback
Changelog v4 (REV-1):
1. MFPR_BASE renamed as MV_MFPR_BASE and defination moved to board config file
2. val= removed from config-write logic

[U-Boot] Full Arm emulator to run under x86
Hi I am new to uboot and I would like to learn it under an emulator instead of a remote target. For instance, I'd like to experiment it with the Android operating system. So far, I have tried qemu (utility qemu-system-arm) to boot the kernel or an arm+uboot bootable sd flash image on x86 architecture and the result was unsuccessful. My purpose is not to run for example Android on an x86 architecture, because i know that there's Android for i386. However, more of a full Arm system emulator that should be able to boot U-boot bootloader and then the Linux kernel, and also a bootable block device or image. thank you, -toan ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] [PATCH][NEXT] hwmon: do not init sensors on startup
The U-Boot Design Principles[1] clearly say:
Initialize devices only when they are needed within U-Boot, i.e. don't
initialize the Ethernet interface(s) unless U-Boot performs a download
over Ethernet; don't initialize any IDE or USB devices unless U-Boot
actually tries to load files from these, etc. (and don't forget to
shut down these devices after using them - otherwise nasty things may
happen when you try to boot your OS).
So, do not initialize and read the sensors on startup.

[U-Boot] [PATCH v2] tsec: Revert to setting TBICR_ANEG_ENABLE by default for SGMII
The following commit: commit 46e91674fb4b6d06c6a4984c0b5ac7d9a16923f4 Author: Peter Tyser pty...@xes-inc.com Date: Tue Nov 3 17:52:07 2009 -0600 tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode Removed setting Auto-Neg by default, however this is believed to be proper default configuration for initialization of the TBI interface. Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the XPedite5370 XPedite5500 boards that use a Broadcomm PHY which require Auto-Neg to be disabled to function properly. This addresses a breakage on the P2020 DS MPC8572 DS boards when used with an SGMII riser card. We also remove setting CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the default setting is sufficient for them. Additionally, we clean up the code a bit to remove an unnecessary second define.

[U-Boot] Memset 0 in heap initialization?
In common/dlmalloc.c in the heap initialization mem_malloc_init() [1] it looks like the whole heap is initialized with zero: memset((void *)mem_malloc_start, 0, size); What's the reason for doing this? I know that the .bss segment has to be zeroed at system start up, but why doing this for the heap, too? It was my understanding that one could make no assumption about the initial content of memory returned by malloc() (?). Sorry if I miss the obvious ;) Thanks Dirk [1] http://git.denx.de/?p=u-boot.git;a=blob;f=common/dlmalloc.c;h=e9bab09b8eac7c0ec4900a3685f15a807b448c31;hb=refs/heads/master#l1529 ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

To let the driver know which devices are 16-pin it is necessary to define
CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to
create an array of {chip, ngpio} tuples that are used to determine the
width of a particular chip. For backwards compatibility it is assumed that
any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.

Re: [U-Boot] [PATCH] usb_ether: register usb ethernet gadget at each eth init
Hi, 2010/12/1 Lei Wen lei...@marvell.com: Since the ether may not be the only one usb gadget would be used in the uboot, it is neccessary to do the register each time the eth begin to work to make usb gadget driver less confussed when we want to use two different usb gadget at the same time. Usb gadget driver could simple ignore the register operation, if it find the driver has been registered already.

[U-Boot] [PATCH] Fix to make U-Boot work with more USB sticks
I am sending this to the list looking for comments. Testing has been
confined to just a few USB sticks - no USB hard drives, USB card
readers, etc. But there are reports on the mailing list of problems
with U-Boot's detection of USB mass storage devices.
We have had a lot of problems with different USB sticks, specifically
the faster bulk storage devices. Two of these sticks have
a problem where they do not respond to a USB descriptor submission
within the allowed U-Boot timeout. This seems to only happen when a
REQUEST SENSE is submitted immediately after a TEST UNIT READY fails.
There is also some oddness with reset, where some devices need more
than one reset. This appears to be due to faulty reset code in U-Boot.
USB sticks where this this problem has been noticed are:
ID 13fe:3800 Kingston Technology Company Inc.
ID 0930:6545 Toshiba Corp. Kingston DataTraveler 2.0 Stick (4GB)
/ PNY Attache 4GB Stick
This problem has been reproduced on the Tegra 20 Seaboard, but it is
TBD whether it happens on other ARM platforms with HS USB also.
This patch:
1. Increases the USB descriptor submission timeout to 3 seconds since the
original 1 second timeout seems arbitrary
2. Replaces the delay-based reset logic with logic which waits until it
sees the reset is successful, rather than blindly continuing
3. Resets and retries a USB mass storage device after it fails once, in
case even 3 seconds is not enough
BUG=chromiumos-6780
TEST=tried with four different USB sticks, including two which previously
failed
