I've tested your patch on mx31ads. Unfortunately it bricks the board.
There are no messages on console. The latest u-boot version that
works on this board is 2010.09. I've compiled u-boot using ELDK-4.2.

If you have any ideas, I'm ready to test your patches.

Felix.

Thanks for testing it.

Could you please try to use change to CONFIG_SYS_TEXT_BASE = 0xa0000000

in board/freescale/mx31ads/config.mk ?

Thanks,

Setting CONFIG_SYS_TEXT_BASE to 0xa0000000 in mx31ads.h
fixes the problem.

You can add

Tested-by: Felix Radensky felix at embedded-sol.com

Unrelated to your patch, u-boot prints

CPU:   Freescale i.MX31 rev 2.0 unknown at 531 MHz.Reset cause: WDOG

Do you think "unknown" can be replaced by something more meaningful ?

Also, environment settings are completely broken, environment address
clashes with u-boot address. I'll submit a patch to fix that after 
your patch
goes in.

Thanks for your efforts to keep this board support alive.

Felix.

Ok, I will send v4 of this patch tomorrow and will add your Tested-by line then.

Yes, I agree. This is common MX31 code and I will take a look at fixing it.

Sounds like a good plan.

I don't see the "unknown" string on my MX31PDK board.

Can you try the patch below and let me know if it gets rid of it?

diff --git a/arch/arm/cpu/arm1136/mx31/generic.c b/arch/arm/cpu/arm1136/mx31/gen

Please ignore my last message. I think you could try:

[U-Boot] [PATCH v3] mx31ads: Use the new relocation scheme

[Fabio Estevam]

This fixes the MX31ADS build by using the new relocation scheme.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
---
Changes since v2:
- Use PHYS_SDRAM_1 in get_ram_size
- Remove local config.mk

Changes since v1:

- Fixed lines over 80 characters.

Build tested only.

Do not have the hardware handy to test.
