mtd: spinand: gigadevice: Add continuous read support
GD5F1GM9 supports a high-speed Continuous Read (CR) mode which allows the entire memory array to be read out by a single read command without re-issuing the 13h “Page Read to Cache” command for every page. Datasheet summary Feature register B0[3] (NR bit) 1 = Normal Read (default) 0 = Continuous Read (CR) ECC status register 7Ch Normal read: bits [3:0] → ECC status of last page Continuous read: bits [7:4] → accumulated max bit-flips over the whole sequential read operation.
