Can you point me to the xt25f128b datasheet?
We'll have to re-spin your patch to the latest spi-nor/next.
Microcai sent a similar patch at
https://patchwork.ozlabs.org/project/linux-mtd/patch/CAMgqO2y9MYDj6antOaWLBRKU8vGEwqCB-Y1TkXTSWsmsed+W6A@mail.gmail.com/
Would you sync with Microcai and send another version?
Cheers,
ta
