The NAND boot on our board finally works. It turned out to be a silly
bug in the DCD table. The DCD table turned off the GPMI clocks which
of course prevented the ROM from loading the rest of the image.

I just resent my version of this patch, but included the missing check
for a valid image and the confirmation question from your version.

Maybe you could give this a test on your board.
