Subject: spi-nor: add support for XT25F128B & XT25Q64
|
|
|
|
This adds support for the XT25F128B as found on the RockPi4b SBC.
|
|
- Ricardo Pardini <ricardo@pardini.net> 23/jan/2023: add XT25Q64 SPI NOR chip
|
|
- found on HK's vendor tree: https://github.com/hardkernel/linux/blame/05e3dc1688758bd401e0f7cdd9809a3f9251f7c1/drivers/mtd/spi-nor/spi-nor.c#L1024-L1026

This continues the efforts done in [1] & [2] that went stale. I've
|
|
tested this patch on my RockPi4b which only has the xt25f128b (and not
|
|
the xt25f32b as also propsed in [2]). I have tried to obtain a copy of
|
|
the datasheets but was unable to find them. Not sure whre you would get
|
|
them.
|
|
|
|
While [1] was already for the new spi-nor layout it was missing the bits
|
|
in the core.{c,h} files.
