p.s.

If you want me to I can merge this, or the next version into my sunxi-wip
branch so that people can play with it. Chances are I will do that anyways
one of these days to play with it myself.

Talking about playing with this, can you provide a quick step by step on
howto setup the ubifs stuff under Linux, assuming a kernel + dts with
working nand support are present ?
