-Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
-
-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.
