From 1c7fe6b438433e16d5b1211380c305351ac38299 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 9 Jun 2016 20:10:11 +0200 Subject: [PATCH] mtd: nand: add ESMT manufacturer MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I got device with ESMT (Elite Semiconductor Memory Technology Inc) F59L1G81MA flash that was detected as: [ 0.852034] nand: device found, Manufacturer ID: 0xc8, Chip ID: 0xd1 [ 0.858402] nand: Unknown NAND 128MiB 3,3V 8-bit [ 0.863031] nand: 128MiB, SLC, page size: 2048, OOB size: 64 According to the F59L1G81MA datasheet (and Read Id documentation) C8h is a "Maker Code" which should mean ESMT. Add it to fix above "Unknown".
