I actually tried several approaches to this problem and I think, I have a good idea about how to create a fully asynchronous mtd driver, which can handle different device models. Unfortunately, I had other commitments so I couldn't advance my mtd stuff.

Recently I was going to go back to it, but then I was asked to implement some additional functionality in rapidio subsystem, which I'll have to take care of first.
