1) Can you pointed us the Linux changes along with discussion thread
about spi-mem, and spi-nand.

2) If my understanding was correct, spi-mem is replacement for spi-nor
controller drivers from driver/mtd/spi-nor in Linux.

3) If so is fsl_qspi spi-nor driver moves to drivers/spi area? yes
then how does flash changes handled by spi-mem.

4) we have zynq qspi controller which has extensive features like dual
flash(stacked and parallel) does spi-mem support these flash specific
changes?

5) Better to send spi-mem and spi-nand changes separately, for better reviewing.

6) We have DM MTD layer in ML, better to send the changes on-top [1]
