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, Miqu=C3=A8l
