4 Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
5
6 This patch adds the W25N01GV NAND to the table of
7 known devices. Without this patch the device gets detected:
8
9 nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
10 nand: Unknown NAND 256MiB 1,8V 8-bit
11 nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
12
13 Whereas the u-boot identifies it as:
14 spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
15 SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
16
17 Due to the page size discrepancy, it's impossible to attach
18 ubi volumes on the device.
