Evening! Alright so I built against the latest master, enabled all the root ports (0-12), disabled the NVME (root port 8)? for good measure (although I also tried with it remaining enabled).
I still don't see the device under either "pci" in the EFI shell or under "lspci" once Ubuntu is booted. I don't have any other PCI cards that I could test here, unfortunately. How shall I go about debugging this further? Can I get logs out of coreboot somehow?
