Subject: [PATCH v5 2/2] mtd: cfi_cmdset_0002: add support for Samsung K8D3x16UxC NOR chips
Date: Fri, 17 Dec 2010 10:59:47 +0100 [thread overview]
Message-ID: <20101217095947.8560.45288.stgit@shiryu> (raw)
In-Reply-To: <20101217095941.8560.75355.stgit@shiryu>
These chips report CFI v3.3 [1], so patch them on the fly to the more
correct v1.3.
Discussed and tested by the OpenWRT people [2].
