So far I am glad to see all these changes.

About the ->select_chip() removal, I wonder if it would not be better
to also change the local variables "chipnr" or "chip_number" (or
even "i") that suggest that this ID selects a chip, while it
actually selects a die in a chip (and it is possible to have multiple
die on a chip, so multiple CS for one single NAND chip).

Do you think it is worth the change ? If yes, would it fit in this patch
or is it better to do this change elsewhere?

Thanks,
Miquèl
