[U-Boot] U-Boot for AMCC Sequoia Board (PPC440EPX) fails to boot for version 2009.11-rc1 onwards

[Hayes,Doug]

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).

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.
