Signed-off-by: Andreas Rammhold --- 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.
