[PATCH 0/3] fixups for OOB ECC problems

Hello,

Now that we have added the possibility that mtd->read_oob returns
-EUCLEAN or -EBADMSG for corrected bitflips and for uncorrectable errors,
respectively, there are more pieces of code that need to take this into
account. These patches should address some of these by ignoring bitflips
when bit accuracy is not needed or by ignoring corrected errors when
scrubbing would be unnecessary.

There are still other cases to address, for example, some flash-based BBT
code.

This applies on top of l2-mtd-2.6.git. Patch 3 is an amendment to commit
abf386c475beab813dc9b3366e592e00255e987a, ("mtd: nand: handle ECC errors
in OOB"), so it can be squashed in if you want. Let me know if you want
me to do this and do a resend.

Brian
