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