[MTD] [OneNAND] 2X program support
The 2X Program is an extension of Program Operation. Since the device is equipped with two DataRAMs, and two-plane NAND Flash memory array, these two component enables simultaneous program of 4KiB. Plane1 has only even blocks such as block0, block2, block4 while Plane2 has only odd blocks such as block1, block3, block5. So MTD regards it as 4KiB page size and 256KiB block size Now the following chips support it. (KFXXX16Q2M) Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M, Mux: KFM2G16Q2M, KFN4G16Q2M, And more recent chips Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
