From: Arseniy Krasnov <avkrasnov@xxxxxxxxxxxxxx>
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")
