Ah, ok, I see. But isn't a host bridge needed to bind all the PCI-to-PCI bridges under a single bus, in order to get the global resource assignment I was referring to? Regarding the PCI IDs, I have started to work with Marvell to see what is possible. I, unfortunately, haven't received the answer for now.
