mtd: nand: add support for Samsung K9LCG08U0B
Assume that: tmp = ((extid >> 2) & 0x04) | (extid & 0x03)); From the K9LCG08U0B's datasheet, we know that: the oob size is 640 when tmp is 6; the oob size is 1024 when tmp is 7; Signed-off-by: Huang Shijie <b32955@freescale.com> [Brian: fixed compile issue] Signed-off-by: Brian Norris <computersforpeace@gmail.com>
