Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
Date: Tue, 24 Jul 2018 16:09:14 +0200 [thread overview]
Message-ID: <20180724140914.15986-1-john@phrozen.org> (raw)
From: Christian Lamparter <chunkeey@gmail.com>
This patch adds the W25N01GV NAND to the table of
known devices. Without this patch the device gets detected:
nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
nand: Unknown NAND 256MiB 1,8V 8-bit
nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
Whereas the u-boot identifies it as:
spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
Due to the page size discrepancy, it's impossible to attach
ubi volumes on the device.
