Some part of this patch was added to the generic patches as it was
needed also for some other target. Do not add it here any more.

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.
