--ARG…. Thanks, Outlook. :P
Andy,
Check the devicetree.cb file in your …/src/mainboard/amd/persimmon folder. Mine shows:
device pci 15.0 off end # PCIe PortA
device pci 15.1 off end # PCIe PortB
device pci 15.2 off end # PCIe PortC
device pci 15.3 off end # PCIe PortD
I’m not 100% certain, but I suspect that changing these from “off” to “on” will enable the devices. Try the change and see if the console output starts reflecting the devices you’re looking for.

Subject: [coreboot] PCIe devices not enabled on amd/persimmon
Howdy,
I've got an AMD/persimmon board, with the agesa family 14 northbridge on the CPU, and the SB800 southbridge. Both have 4 PCIe ports on them, but coreboot isn't enabling or enumerating any of the PCIe devices on the SB800. Does anyone have any ideas for me? The two devices on that southbridge are an NEC USB3 and a Mini-PCIe slot.
Pasting the console output below for those interested:
