And this is a bug.  Statically initialized pointers are supposed to be
fixed up during relocation.  I've got a big patch set which I'll be
posting this evening (and would have already posted if I wasn't having
SMTP problems) that solves this for 5xx, 5xxx, 82xx & 83xx.

I think the intent of relocation is that the u-boot image can always
put itself at the end of SDRAM, regardless of how much ram is on the
board.  Not important for ports that have soldered down chips, but
useful if the board has expandable memory.

Cheers.
