I guess it's used, but you need an acpi name for all devices along the
path. "LIBR" is the name for the LPC device, there should also be one
for the PCI bus/domain. I would try `src/northbridge/amd/pi/00660F01/
northbridge.c`.

Could you point me to an example to know what I have to look for, p.e, to a good supported board or something related. I'm still introducing me in the coreboot world :)

Regards,

Jorge
