Thanks. I am always using cf8/cfc, but I'm calling different functions.
I've never understood all the different functions:
I know that pci_write_config32 tries to find the correct pci_ops to use,
pci_conf1_write_config32 tries to do it directly, but I don't know why one
would work and not the other. V3 only has one pci bus ops struct defined.
