Absolutely agreed, vor v3.

Good catch, I'll take your syntax also. As you probably have guessed, my testing
is with a 16 bits wide NAND.

Okay, great. I'm working on it. I'll post the v3 to not forget, and then let's
wait until I have pxa3xx support sorted out. I'll repost anyway the driver once
pxa3xx support is ironed out. In the meantime other reviewers could spot
something I overlooked.

Cheers.
