mtd: nand: Add core infrastructure to support SPI NANDs
Add a SPI NAND framework based on the generic NAND framework and the spi-mem infrastructure. In its current state, this framework supports the following features: - single/dual/quad IO modes - on-die ECC Signed-off-by: Peter Pan <peterpandong@micron.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
