-Subject: [PATCH] ath79: fix block protection clearing
-
-The block protection bits of macronix do not match the implementation.
-The chip has 3 BP bits. Bit 5 is actually the third BP but here the
-5th bit is SR_TB. Therefore the patch adds SR_TB to the mask. In the
-4.19er kernel the whole register was simply set to 0.
-
-The wrong implementation did not remove the block protection. This led
-to jffs2 errors in the form of:
-"jffs2: Newly-erased block contained word 0x19852003 at offset 0x..."
-This caused inconsistent memory and other errors.
