I remember a similar case where flashrom was unable to write, and that
board also had a second chipset match. We might have the same issue
here: To PCI devices with the same ID, one acts as southbridge and the
other one is unused. We might enable the wrong one here and might have
to refine detection a bit. OTOH, a flash chip is detected, so we know
that write was enabled on the address space mapped to the flash chip
(but that write enable might have not been done by flashrom).

Side note: We should print the PCI ID for the second chipset match as well.

Could you run the following command as root and post the results?
That should help us determine which one of the CK804 southbridges we
However, it is possible that we enabled the right southbridge due to
pure luck and there is a separate write protection (jumper or solder
bridge or something controllable in software). If that is the case,
somebody has to find out how to enable writes by reverse engineering or
by looking at the docs if the docs are good.
