Review request for Default. Description ------- Changeset 9679:7e980b7d406c --------------------------- mem: Make the buses multi layered This patch makes the buses multi layered, and effectively creates a crossbar structure with distributed contention ports at the destination ports. Before this patch, a bus could have a single request, response and snoop response in flight at any time, and with these changes there can be as many requests as connected slaves (bus master ports), and as many responses as connected masters (bus slave ports). Together with address interleaving, this patch enables us to create high-throughput memory interconnects, e.g. 50+ GByte/s.
