Oops. Maybe I need to back up a tiny bit here.

I have a NOR flash, not a NAND flash.

I have been trying to compile UBIFS into u-boot for the last little
while and keep stumbling over NAND unresolveds at link time. So, I
have to ask the question: "Is it reasonable to expect UBIFS to work in
NOR  flash on a MPC8323ERDB with u-boot-2011.03 and if so, what might
be the pitfalls?"
