Compatibility & sourcing notes
Both are SPI NAND with the same command framework, page size, and WSON-8 footprint, but not a transparent drop-in: Winbond and GigaDevice differ in on-die ECC strength, ECC-status bit encoding, spare-area parity layout, and bad-block/OTP handling, so the MTD/flash driver and ECC-status parsing must be adapted. Verify ECC config, spare-area map, bad-block scheme, voltage, and timing per datasheet.
Registers and interface are similar and firmware largely ports, but the package/pinout differs — re-layout and validate in your design.
