That's what I was afraid of.

I was able to get u-boot to start coming up.  The only way I made it happen
was by changing:
Move.l #(CFG_INT_FLASH_BASE + 0x21), %d0
To
Move.l (#CFG_INT_FLASH_BASE + 0x161), %d0

I downloaded CodeWarrior and looked at the code that was generated and that
is what they used.  I haven't looked into it at all.
