MTD operation modes
: OOB data are placed at the given offset (default) : OOB data are automatically placed at the free areas which are defined by the internal ecclayout : data are transferred as-is, with no error correction; this mode implies MTD_OPS_PLACE_OOB
These modes can be passed to ioctl(MEMWRITE) and are also used internally. See notes on "MTD file modes" for discussion on MTD_OPS_RAW vs. MTD_FILE_MODE_RAW.
