It sounds like it isn't 'NAND' at all, as far as you're concerned. It's
a disk drive of some form. Usually these things present themselves as
IDE, so you'd use the IDE driver. If it has its own 'special' interface
then you probably want a dedicated block driver for it; nothing to do
with the MTD subsystem at all.
