-Subject: [PATCH 1/2] mtd: spi-nor: add block protection flags to macronix
-
-Macronix flash chips support block protection by using BP bits in the
-read status register. Add the corresponding flag to indicate block
-protection support.
-
-Otherwise, locked blocks are not unlocked when requested.

+Subject: [PATCH] mtd: spi-nor: use 4 bit locking for MX25L12805D
+
+Macronix MX25L12805D supports locking with 4 block
+protection bits in its status register. Add the corresponding
+flag in order to clear these bits when unloking the flash.
+
+Otherwise, the flash might not be writable depending on the state
+left by the bootloader.
+
+Tested-on: Ubiquiti UniFi AC Lite (ath79)
+
+Fixes commit 62593cf40b23 ("mtd: spi-nor: refactor block protection functions")
