[coreboot] Coreboot NB RS780 Routing

Check the devicetree.cb. set the correct configuration of
gppsb_configuration and gpp_configuration.

Set the needed port as

device pci x.0 on end # xxxxx



Please uncomment the PciePowerOffGppPorts() in rs780_pcie.c to see what
we can see.


I assume the PCIE GPP you mentioned is GPPSB, which covers the dev
4,5,6,7. The Gpp

covers dev 9,a.

Hi all,


In my AMD RS780 project, two Marvel Lan chips connect to PCIE GPP port
One wireless lan chip connects to PCIE GPP port 2.


In AMI BIOS, I see Bus 0 Dev4&5&6.
But in coreboot, I see BUS 0 DEV 9&a. 


Is that normal?
