-Subject: [PATCH] mtd: spi-nor: fix 4-byte opcode support for w25q256
-Date: Wed, 15 Apr 2020 16:48:30 +0300
-Message-ID: <1586958510-24012-1-git-send-email-mantas@8devices.com>
-
-There are 2 different chips (w25q256fv and w25q256jv) that share
-the same JEDEC ID. Only w25q256jv fully supports 4-byte opcodes.
-Use SFDP header version to differentiate between them.
-
-for OpenWRT only: rebased to linux-v5.4
