Subject: [PATCH] mtd: cfi_cmdset_0002: PPB locking support for larger capacity devices
Date: Wed,  5 Apr 2017 13:57:43 +0200	[thread overview]
Message-ID: <20170405115743.27441-1-mathias.thore@infinera.com> (raw)

Currently cfi_cmdset_0002.c supports advanced sector protection scheme
for devices with 512 or fewer sectors. This patch increases the limit
to enable advanced sector protection on devices with larger capacity.
