>From looking at the code, I wonder *how* you did implement the external logic 
on your board. I would have thought you connected some of the NAND control 
pins to 405EP GPIO's. But this doesn't seem to be the case. You are accessing 
the CMD/ALE singals at different addresses. So what exactly is you external 
NAND controller logic?

If not, I suggest you take a look at:

board/esd/common/esd405ep_nand.c

This is an 405EP NAND implementation with external logic and signals attached 
to GPIO's.
