Hi,
I have an intel Xeon-D board with vendor BIOS and I trying to get it to work
with the Coreboot.
I am successful in booting OS through grub payload from
coreboot-4.9-1259-gc4f3972-dirty.
The problem is some of the PCI devices are missing while scanning PCI in
coreboot but detecting all PCI devices properly in vendor bios.
Below is vendor BIOS PCI Listing

Below is the device missing in coreboot PCI listing which differs from the
vendor firmware:

00:03.2
00:03.3

pci_probe_dev function in pci_device.c seems to probe with respect to device
number and I couldn't find where the bus device function number is set
