[U-Boot-Users] [PATCH] 85xx: extended cpu identification
The current cpu identification code is used just to return the name
of the processor at boot. There are some other locations that the name
is useful (device tree setup).
Also, we add a feature field to convey useful attributes of the processor.
(for 85xx we have a single feature to tell if the processor has a crypto
engine or not).

Re: [U-Boot-Users] Latest U-Boot MD5 compile error??
All, Okay, I have tracked this farther into the compilation problem. I have no reason to believe that 'my system' is any different that any standard stock FC5 box, other than its been original since FC5 was released, pending updates. Looking through the code, though I haven't nailed it, it would seem that between: #include typedef __kernel_dev_t dev_t; #include typedef unsigned int__kernel_dev_t; There are discrepancies in how '__kernel_dev_t' is defined. Now, I haven't found yet where 'dev_t' is defined. Can somebody possibly think of a reason this is being thrown? Again, I have downloaded the latest U-boot git tree, like 5 times to ensure that I am not using 'corrupted' code. Also have ensure that this problem doesn't exist prior to commit SHA - 8cf30809a82902a471866d2f07725ce3b8a22291. -Russ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 28, 2008 2:56 PM To: [EMAIL PROTECTED] Cc: u-boot-users@lists.sourceforge.net Subject: Re: [U-Boot-Users] Latest U-Boot MD5 compile error??

I too am suffering from this very slow JFFS2 problem. It is especially bad for NAND flash. I modified the fs/jffs2/Makefile to use fs/jffs2/jffs2_nand_1pass.c instead of jffs2_1pass.c, but that would not build. I eventually fixed that by quite large changes, but it still ran very slowly despite reading larger chunks of NAND. Has anyone out there fixed this problem?

That seems not to be a minor problem. If CFG_MAX_NAND_DEVICE > 1,
board_nand_init() will be called twice with the base address from
CFG_NAND_BASE_LIST. The only problem I see is that the UPM interface is
setup twice.

I know, sniff.

I already had a closer look and realized a difference in writing the UPM
array. In fsl_upm.c there is:
static void fsl_upm_setup(struct fsl_upm *upm)
{
int i;
/* write upm array */
out_be32(upm->mxmr, FSL_UPM_MxMR_OP_WA);
for (i = 0; i < 64; i++) {
out_be32(upm->mdr, upm->array[i]);
out_8(upm->io_addr, 0x0);
}
/* normal operation */
out_be32(upm->mxmr, FSL_UPM_MxMR_OP_NO);
while (in_be32(upm->mxmr) != FSL_UPM_MxMR_OP_NO)
eieio();
}
But in my driver I fold the machine address into mbmr for each value:
out_be32 (&lbc->mbmr,
(in_be32 (&lbc->mbmr) & ~(MxMR_OP_NORM | MxMR_MAD)) |
MxMR_OP_WARR | (i & MxMR_MAD));
^
Seem also that defines a duplicated :-(.
Has it been tested with an MPC85xx? I will do some more test now.
Wolfgang.

[U-Boot-Users] can u-boot run standalone in qemu(qemu-system-arm) without kernel image(for mainstone II)
hi, all I'm a newbie to both u-boot and qemu. Maybe it's a silly question, but I can not find the solution through the Internet for almost 2 weeks, sorry :( Here is my question: I wanna run u-boot as a standalone app (or image?) in qemu, and I do't wanna any create linux image. Is that possible? I just wanna to study u-boot. And now, my idea is to create a flash image with u-boot, how about this way? Any reply would be appreciated. Thank you in advance :) stones. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Personally I think we should remove UPM programming code from the
fsl_upm_nand.c, and program the UPM via its own interface, see this post:

I see. I think there will be a problem with a
static void fsl_upm_start_pattern(struct fsl_upm *upm, u32 pat_offset)
{
out_be32(upm->mxmr, FSL_UPM_MxMR_OP_RP | pat_offset);
}
static void fsl_upm_end_pattern(struct fsl_upm *upm)
{
out_be32(upm->mxmr, FSL_UPM_MxMR_OP_NO);
while (in_be32(upm->mxmr) != FSL_UPM_MxMR_OP_NO)
eieio();
}
Since it zeroes these values. No problem though, this should
be replaced by the Linux' versions, that is
clrsetbits_be32(upm->mxmr, MxMR_MAD, MxMR_OP_RP | pat_offset);
for start_pattern, and clrbits32(upm->mxmr, MxMR_OP_RP); for
end_pattern.
So, this will leave your values intact, and will work for all boards as
well.
> Seem also that defines a duplicated :-(.
No problem. Please, remove the ones you don't like, and leave the ones
you do like. :-) Feel completely free to do everything you need to make
fsl_upm_nand.c work on your hardware, and then we'll see what we can do
to make our hardware work together.
As for UPM programming, as I've said, just remove UPM programming code
from the NAND driver, and leave it in the board file until (if) we'll
start using generic interface.
> Has it been tested with an MPC85xx? I will do some more test now.
Yup, MPC8555.

I've not yet looked at the code so you know more than I do, but we were speculating that the JFFS layer was not building an inode table in RAM, so that each time it finds a file it goes back to the begining of the fs and starts searching for the next without remembering what it has already seen. Does this make sense?

UNDEF_SYM is a shell variable in the main Makefile used to force the

Yes, easily (because there is no single user). The same is needed for mpc8xx.h and mpc8260.h (defines are almost the same, just few differences which needs some attention though). But the bad news for mpc8xx and mpc8260 is that there are a lot of users of these defines. So this cleanup I'll leave for the "better times". - - - - From: Anton Vorontsov <[EMAIL PROTECTED]> Subject: 83xx/85xx: further localbus cleanups Merge mpc85xx.h's LBC defines to fsl_lbc.h.

We could compile that file with -fno-strict-aliasing, which is probably warranted anyway for the kind of pointer manipulation that malloc needs to do. -Scott - This SF.net email is sponsored by: Microsoft Defy all challenges.

The 42 is an obscure reference to the Hitchhiker's Guide to the Galaxy - the answer to the question of life, the universe and everything. In other words, it is a totally arbitrary number. Your use of +31 is not a *ROUNDING*, it is *CEILING* and thus I claim it is arbitrary, especially with the +1 to the divisor if your baud rate is suppose to be 115200 baud. You don't understand your hardware (if it makes you feel better, neither do I, but it is important that *you* understand it). >> Are you sure your input frequency is 140MHz and not 144MHZ???

Take > M5253EVBE for example, the input clk is 11Mhz. Then, it multiply up and > divide down for CPU and bus frequency. This *REALLY* makes your formula wrong. According to the MCF5253 Reference Manual Eqn. 15-1, the baud rate is fsys / (32 * divisor) and fsys is 70MHz, *NOT* 140MHz. baud = SysClk / (32 * divisor) divisor = (70e6 / 32) / baud divisor = 2187500 / 115200 divisor = 18.99 => 19 To *round*, add 1/2 the desired baud rate divisor = ((70e6 / 32) * (baud / 2)) / baud divisor = (2187500 + 57600) / 115200 divisor = 19.5 => integer truncation => 19 This means gd->bus_clk is *70MHz* (1/2 the CPU frequency), *NOT* 140MHz as you assume (note that this matches the Reference Manual). I return to my contention: Note, however, that (gd->baudrate / 2) is going to be relatively small compared to gd->bus_clk and (gd->baudrate * 16), so I suspect that the above formula could be changed to the following formula with no significant impact in accuracy: counter = (u32) ( ((gd->bus_clk + (gd->baudrate * 16)) / (gd->baudrate * 32); Simplifying the *32 factor to match my formula above: counter = (u32) ( ((gd->bus_clk / 32) + (gd->baudrate / 2)) / gd->baudrate); counter = ((70e6 / 32) + (115200 / 2)) / 115200 counter = 19 (after inter truncation) Note that, without adding (baudrate / 2) - rounding, the above formula results in a divisor of 18 rather than the proper 19. THIS IS YOUR PROBLEM and also what your fix should be. If you rounded properly, the baud rate calculation would work without all the magic. Here is what your change actually does: /* Setting up BaudRate */ counter = (u32) (gd->bus_clk / (gd->baudrate)); This divide is doing an integer truncation and you are losing significant digits. 70e6 / 115200 = 607.64 => integer truncation = 607 counter = (counter + 31) >> 5; This is "ceiling", but you've already lost the digits due to the previous divide with integer truncation (no rounding). (607 + 31) / 32 = 19.9 => integer truncation = 19 You get lucky and get the right answer even though you don't deserve it. ;-) if ((gd->bus_clk > 1) && (gd->baudrate >= 115200)) counter++; This is totally bogus. gd->bus_clk == 70e6 so this is *always false.* >> Looking at the MFC5407 (arbitrarily, not knowing what processor you > have), the dividers are >> as expected and *do not* match your "- 31" >> calculations.

Re: [U-Boot-Users] [PATCH]env_nand.c Added bad block management for environment variables
Scott,
Here is a new version of my patch to env_nand.c. Thanks for the good comments.
Fixed a problem with the new code that allowed it to read a
environment area even
if it contained a bad block after the good environment data.

What about the non-redundant version of env_relocate_spec?
Also, this isn't checking the size, so it's not really an appropriate name.

If the environment can span multiple blocks, we should be able to skip
blocks internally rather than requiring contiguous good blocks.

Err, with an offset increment in the loop, of course.

A better comment would tell the reader *why* you made the change. Suggestion... The formula "counter = (u32) (gd->bus_clk / (gd->baudrate)) / 32" can generate the wrong divisor due to integer division truncation. Round the calculated divisor value by adding 1/2 the baudrate before dividing by the baudrate.

[U-Boot-Users] [GIT PULL] avr32 update
Hi Wolfgang,
Please pull the 'master' branch of
git://git.denx.de/u-boot-avr32.git master
to receive the below updates.
The SPI stuff and a few other patches I've posted are not included here
since they aren't really avr32-related. I'm hoping you'll still apply
them before the merge window closes.
David Brownell (2):
avr32: stk1002 and ngw100 convergence
avr32: Disable the AP7000 internal watchdog on startup
Haavard Skinnemoen (15):
avr32: Use correct condition around macb clock accessors
avr32: Get rid of the .flashprog section
avr32: Add support for the ATSTK1006 board
avr32: Clean up the HMATRIX code
avr32: Remove unused file cpu/at32ap/pm.c
avr32: Use new-style Makefile for the at32ap platform
avr32: Rename pm_init() as clk_init() and make SoC-specific
avr32: Put memset in its own section
avr32: Use the same entry point for reset and exception handling
avr32: Do stricter stack checking in the exception handler
avr32: Rework SDRAM initialization code
avr32: Fix two warnings in atmel_mci.c
avr32: Fix wrong error flags in atmel_mci driver

[U-Boot-Users] Command history no longer working
Hi, I have observed that after this commit, the command history is no longer working: --- commit 597f6c26a18b389903a64692bacbf9a1ca69355b Author: James Yang <[EMAIL PROTECTED]> Date: Mon May 5 10:22:53 2008 -0500 Fix readline_into_buffer() with CONFIG_CMDLINE_EDITING before relocating When CONFIG_CMDLINE_EDITING is enabled, readline_into_buffer() doesn't work before relocating to RAM because command history is written into a global array that is not writable before relocation. This patch defers to the no-editing and no-history code in readline_into_buffer() if it is called before relocation. --- Based on the comments, I dont understand why it ceases to work because, in my case, U-Boot runs entirely from RAM (it is copied from flash to RAM by a first stage bootloader). I have CONFIG_CMDLINE_EDITING defined. Hugo V.

Well after reading through the code in common/main.c, I figured that by setting GD_FLG_RELOC in my board init function: gd->flags |= GD_FLG_RELOC; command history would be working again, and it did. But is it the right thing to do? I noticed that not a lot of platforms/boards set GD_FLG_RELOC so command history will probably cease to work for these boards also? Hugo V.

All right then, my board is based ont he ARM926, so I have added the code to my misc_init_r() function. While looking into this problem, I think I have found a small glitch with the original patch for the commit 597f6c26a18b389903a64692bacbf9a1ca69355b.

First you should be sure if that's exactly what you want. If you just want to play with u-boot on x86, porting it to bochs (or another virtual pc) should be easier and have more benefits than your pc. http://bochs.sourceforge.net/ If you want free software to boot your PC, you should have a look at coreboot (linuxbios) as well. It can also boot other PC related (BIOS dependent) operating systems, like freedos, which you probably wont be able to boot with u-boot. There is a port for bochs, so you can already play with it. http://www.coreboot.org/ > The big problem is that full hardware documentation is hard to get. > Depending on your board and the chips used on it, you might be able to > get the documentation, but historically it is a show stopper problem. > This may be changing with hardware becoming more open for linux drivers, > or maybe you will get lucky... Getting a board which is already supported by Linuxbios should be the best starting point to port u-boot on it. Good Luck Markus - This SF.net email is sponsored by: Microsoft Defy all challenges.

Alas, I was unable to make bit-banged I2C to work even with this patch applied. As I mentioned above, it works in Linux, but I'd like to be able to set time to my RTC from u-boot. I have checked that pins are configured properly from status registers (pull-ups are enabled, multi-drive mode is enabled (open drain), etc.). I could read only zeroes from SDA line in u-boot, and using oscilloscope, I see data on line. I can't find differencies in setup with i2c-gpio from Linux. Any ideas?

The fall back image is a user friendly way to unbrick the device. It itself is never overwritten. (In my case a web server with firmware upgrade Java applet, for example). Currently, my flow is as follows (with implementation in redboot) boot loader: enable hardware watchdog if flag A is set clear flag A load normal image, boot else if the normal image was not loaded, boot fallback. else boot fallback the normal image sets flag A when it wants to reboot, then stops servicing the watchdog and resets if normal image either did not set flag A (it crashes) or it did not service the watchdog, the watchdog will reset the board. I wonder if this is a common use and if it makes sense to implement this for mainstream u-boot, or is this very specific?
