Hmm, I'm not terribly opposed to this patch, but you, Pekon, and I
(in my local driver) are all doing something very similar, and I believe
Pekon has gotten the logic wrong one or more times. I believe I actually
have a version of this type of patch locally that could probably be put
into the nand_base layer, with a flag so that drivers could request the
check themselves (something like chip->options |=
NAND_NEED_FF_ECC_CHECK; or pick your own name!).

What do you think? All interested parties please chime in. I can try to
push a patch out soon for you all to test soon, or else I can see about
taking your patches as-is for now, then try to unify them myself
afterward.
