From mboxrd@z Thu Jan 1 00:00:00 1970 From: sergei.shtylyov@cogentembedded.com (Sergei Shtylyov) Date: Wed, 16 Jan 2019 20:51:56 +0300 Subject: [PATCH 1/2] mtd: spi-nor: add Spansion S25FS512S ID In-Reply-To: <610761cf-5a19-c182-07d8-8d118ca20035@cogentembedded.com> References: <610761cf-5a19-c182-07d8-8d118ca20035@cogentembedded.com> Message-ID: <650c47f3-8657-0fc9-81bd-63974bbe06a5@cogentembedded.com> To: linux-mtd@lists.infradead.org List-Id: linux-mtd.lists.infradead.org Spansion S25FS512S flash is currently misdetected as S25FL512S since the latter uses 5-byte JEDEC ID, while the 6th ID byte (family ID) is different on those chips. Add the 6-byte S25FS512S ID before S25FL512S ID in order not to break the existing S25FS512S users.
