+Subject: mtd: rawnand: meson: fix bitmask for length in command word
+
+From: Arseniy Krasnov <avkrasnov@sberdevices.ru>
+
+commit 93942b70461574ca7fc3d91494ca89b16a4c64c7 upstream.
+
+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")
