Currently, I see:

root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/partname
spi-nor-generic
root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/jedec_id
204018204018
root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/manufacturer
cat: /sys/bus/spi/devices/spi1.0/spi-nor/manufacturer: No such file or directory
root@rk3399-station-p1:~# 

After this patch:

root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/partname
XM25QH128C
root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/jedec_id
204018
root@rk3399-station-p1:~# cat /sys/bus/spi/devices/spi1.0/spi-nor/manufacturer
xmc

The advantage of this patch is to provide the partname and manufacturer entries for userspace.

If this is not wanted, feel free to discard this change.
