Is this CN78XX hardware? Also can you confirm the board does not have
any PCI Express (check U-Boot and vendor kernel logs)?
On EdgeRouter 4 (CN70XX) kernel misdetects PCIe ports, and there are
error logs and delays during this, but the board still boots up.
Probably nobody has any OCTEON III board with working PCIe running
mainline kernel, so we should just make the setup fail early.
