[U-Boot] U-Boot for AMCC Sequoia Board (PPC440EPX) fails to boot for version 2009.11-rc1 onwards
Has anyone tried the latest U-Boot on the above board lately? I am building the U-Boot image with "sequoia_config" option and have found it stops booting after version 2009_08. I get no text output for the versions that I have tried: 2009.11-rc1, 2009.11, 2010.03. latest (2011.06). There were a lot of "4xx" changes in 2009.11-rc1 so perhaps one of those has changed how my board comes up. I am just starting to compare code files for differences in order to track it down.
I am compiling with this ELDK "gcc version 4.0.0 (DENX ELDK 4.1.4.0.0)".
I anyone has an idea why my U-Boot hangs please let me know. Thanks for any info.

I do test on Sequoia from time-to-time. No problems here:

This is with ELDK 4.2 (GCC 4.2.2).

Some extra info. U-Boot dies in get_async_pci_freq() (new feature) called from board_early_init_f() when trying to read a byte from 0xC0000005 (CONFIG_SYS_BCSR_BASE + 5).
Perhaps your board is too old and doesn't support reading these CPLD registers. On mine I get:
=> md.b c0000000 20 c0000000: 0f 00 c0 07 00 00 00 80 00 20 00 00 00 00 00 00 ......... ...... c0000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
What do you get on your "old", working U-Boot?
