libmtd: allow write operations when MEMWRITE is not supported
MEMWRITE is a recently introduced write interface for MTD; however, it is only supported on NAND flash. mtd-utils should fall back to old write methods when either ENOTTY or EOPNOTSUPP are returned. This is a showstopper when, for instance, using ubiformat on NOR, which don't have a mtd->write_oob interface (and thus don't support MEMWRITE): ubiformat: formatting eraseblock 2 -- 1 % complete libmtd: error!: MEMWRITE ioctl failed for eraseblock 2 (mtd3) error 122 (Operation not supported) Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com>
