As usual for such problems, check how different firmware configure
memory controller, etc. Get dump of relevant chip registers under
U-Boot and RedBoot and compare them.

Other possible problem area can be firmware -> kernel interface. I'm
not familiar with that particular chip and RedBoot, but it's not
uncommon for different firmware to have different conventions for the
environment in which kernel starts execution.

I'd recommend posting to the specific mail-lists, lkml doesn't seem
a good place for embedded and firmware related questions :)
