that's what cfi_probe does with the chips on these boards.  i have not
made MTD work with these chips.  it's not a priority for me, since
we're using different chips in our design.

don;t know why that happened, that should work.  RevA has 48K of SRAM, right?

what happens when you finally do reboot?

on second thought, how could that work?  if you boot with JP31 closed, your
memory map is swapped.  that would explain why the SRAM probe failed.

are you compiling with CONFIG_EP72XX_ROM_BOOT enabled?  if so, turn it off, you
don;t want that...
