Subject: [PATCH] mtd: nand: add ESMT manufacturer
Date: Thu, 9 Jun 2016 20:10:11 +0200 [thread overview]
Message-ID: <1465495811-3551-1-git-send-email-zajec5@gmail.com> (raw)
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".
