+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")
