I will move several boards to DT, including several pxa3x boards, but not _all_
the boards.

For reference, I said in [1] this :

And as you said Ezequiel, the problem will arise regardless of being DT or not,
it's a lack of conformance of the zylonite board's nand amongst others.

So the timings will have to survive somewhere, whichever place is seen fit.

Cheers.
