Interesting... both the 8313 manual and the manual for a random large
page NAND chip say that the bad block indicator is one byte.

BTW, I was just looking at NAND boot on this chip, and it seems that it
expects ECCM=1 for large page devices, so we should make that the
default (preferably at the same time as we fix this problem, so that we
don't break compatibility with a working version).
