Subject: [PATCH v2] mtd: rawnand: meson: fix bitmask for length in command word
Date: Wed, 29 Mar 2023 10:47:26 +0300 [thread overview]
Message-ID: <3794ffbf-dfea-e96f-1f97-fe235b005e19@sberdevices.ru> (raw)
Valid mask is 0x3FFF, without this patch the following problems were
found:
1) [ 0.938914] Could not find a valid ONFI parameter page, trying
bit-wise majority to recover it
[ 0.947384] ONFI parameter recovery failed, aborting
2) Read with disabled ECC mode was broken.
Fixes: 8fae856c5350 ("mtd: rawnand: meson: add support for Amlogic NAND flash controller")
Cc: <Stable@vger.kernel.org>
