[coreboot] Good v3 port candidate for Socket F

All the AMD Socket F designs are basically going to be the same.  You
have a CPU that contains the Northbridge chipset that has a HT link to
the 2nd CPU.  From the 2nd CPU you then have a HT link that takes you to
your southbridge chipset and all the PCI, PCI-X or PCI-E slots.

The only difference between Broadcom or NVIDIA would be how many memory
slots may or may not be tied directly to each CPU.  Outside of that the
design basically the same in regards to routing.

I am not sure what you mean. You want a HT-PCIe bridge that isn't a
tunnel to the southbridge?
Have you looked at serverworks/broadcom boards?
