Subject: [PATCH] mtd: spi-nor: add dual and quad read support for w25q128
Date: Sun, 10 Nov 2019 13:32:21 +0800
Message-ID: <20191110053222.22945-1-gch981213@gmail.com> (raw)

The only w25q128 variant I could find with 0xef4018 as ID is
w25q128fv, which supports both dual and quad read mode.
Add these two flags in chip info.
