Subject: mtd: spinand: winbond: add support for serial NAND flash
|
||||||
|
|
||||||
|
Add support for W25N01JW, W25N02JWZEIF, W25N512GW,
|
||||||
|
W25N02KWZEIR and W25N01GWZEIG.
|
||||||
|
|
||||||
|
W25N02KWZEIR has 8b/512b on-die ECC capability and other
|
||||||
|
four has 4b/512b on-die ECC capability.
