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.
Best regards,
