It sounds like the BARs mentioned in the processor's manual are relevant when the processor behaves as an endpoint on the bus ("Gadget mode").
When the processor functions as a Root Complex, it enumerates other endpoints according to their BARs. It's own PCIe configuration space is irrelevant in this respect, since noone's asking for that information.
So I don't think there is anything to set up regarding the processor's BARs. Just make sure that the processor is set up to be a Root Complex.
