17/* The abstraction used here is that there are PCI controllers,
18 * each with one (Sabre) or two (PSYCHO/SCHIZO) PCI bus modules
19 * underneath. Each PCI bus module uses an IOMMU (shared by both
20 * PBMs of a controller, or per-PBM), and if a streaming buffer
21 * is present, each PCI bus module has it's own. (ie. the IOMMU
22 * might be shared between PBMs, the STC is never shared)
23 * Furthermore, each PCI bus module controls it's own autonomous
24 * PCI bus.
