Perfect information! Thank you very much.

Please apply the attached patch to the flashrom code, build and run
to see if my idea for enabling writes on this board works.

Unfortunately you must use flashrom -m ppap-2020vl while testing,
because of this I would also appreciate if you can supply lspci -vnn
output, so that the board can be autodetected instead, if there are
unique PCI subsystem IDs.

Best regards
