- Subject: [PATCH 1/2] mtd: spi-nor: locking support for MX25L6405D
- Macronix MX25L6405D supports locking with four block-protection bits.
- Currently, the driver only sets three bits. If the bootloader does not
- sustain the flash chip in an unlocked state, the flash might be
- non-writeable. Add the corresponding flag to enable locking support with
- four bits in the status register.
- Tested on Nanostation M2 XM.
- Similar to commit 7ea40b54e83b ("mtd: spi-nor: enable locking support for
- MX25L12805D")
