I wonder how much sense it makes to call this mtd driver "the
ixp4xx NAND flash driver" if there's hardly anything ixp4xx-specific
in it.

For that matter, I wonder how much sense it makes to submit a
separate NAND driver for every ARM SoC.  For NOR flashes we have
physmap, we should have something similar for NAND.
