This is the flash chip used in the PinePhone Pro[0], found by physical inspection of the board.[1] I cannot find a datasheet, but this chip supports SFDP. This patch depends on SNOR_ID3().[2] Tested done: checked that the Pinephone Pro boots when a ROM is written to /dev/mtdblock0. $ xxd -p /sys/bus/spi/devices/spi0.0/spi-nor/sfdp 53464450060101ff00060110300000ff9d05010380000002ffffffffffff ffffffffffffffffffffffffffffffffffffe520f9ffffffff0744eb086b 083b80bbfeffffffffff00ffffff44eb0c200f5210d800ff234ac90082d8 11c7cccd68467a757a75f7a2d55c4a422cfff030c080ffffffffffffffff ffffffffffffffff501950169cf9c0648fecffff $ md5sum /sys/bus/spi/devices/spi0.0/spi-nor/sfdp de4d6be54e479d60859b0ca8a0ee9216 /sys/bus/spi/devices/spi0.0/spi-nor/sfdp $ cat /sys/bus/spi/devices/spi0.0/spi-nor/jedec_id 257018 $ cat /sys/bus/spi/devices/spi0.0/spi-nor/partname sk25lp128 $ cat /sys/bus/spi/devices/spi0.0/spi-nor/manufacturer siliconkaiser 0. https://wiki.pine64.org/wiki/PinePhone_Pro#Specifications 1.
