Yes, exactly.
Okay so we need some driver that opens/closes this ROM. This has been
done from the dcss block device but that doesn't make sense for most
embedded systems. The MTD allows for this with point(),unpoint().
That should work just fine. It does introduce the MTD as a dependancy
which is unnecessary in many systems, but it will work now.
