Subject: [PATCH v8 2/4] mtd: spi-nor: fix nor->addr_width for is25wp256
Date: Tue, 13 Aug 2019 18:08:13 +0530 [thread overview]
Message-ID: <1565699895-4770-3-git-send-email-sagar.kadam@sifive.com> (raw)
In-Reply-To: <1565699895-4770-1-git-send-email-sagar.kadam@sifive.com>
Use the post bfpt fixup hook for the is25wp256 device as done for
is25lp256 device to overwrite the address width advertised by BFPT.
For instance the standard devices eg: IS25WP256D-JMLE where J stands
for "standard" does not support SFDP.
