- 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.
