[PATCH 2/2] mtd: spinand: winbond: add support for W25N01KW and W25N02LW
From: Md Sadre Alam
Date: Fri Aug 07 2026 - 02:44:08 EST
Add support for the Winbond W25N01KW and W25N02LW SPI-NAND
devices.
The W25N01KW shares the same geometry, OOB layout, and ECC
status handling as the existing W25N01KV, while the W25N02LW
matches the existing W25N02KV/W25N02KW devices and reuses
their OOB layout and ECC status callback.
