I plan to apply this patch but I would like your approval first.

As a summary, the mt29f_spinand driver is a Micron SPI NAND chip
driver interfacing with the raw NAND API (which is 'wrong').

Boris has recently contributed a SPI NAND framework supporting SPI
NAND chips from several vendors, including Micron, that is supposed to
take over this driver.

Do you see anything that should prevent us to remove it now?
