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.
