Unless it's a fairly old chip, or one of Micron's offerings with on-chip
ECC, our current ecc code isn't going to handle it.  I just spent weeks
learning that the hard way.  The ecc code we have checked in is a
hamming code implementation that can correct single-bit errors, and
modern nand chips are requiring algorithms that can correct multi-bit
errors.  Our current code also isn't ready to handle the situation where
the SoC's nand flash controller hardware does ecc with some cooperation
from software.
