+ * underneath. Each PCI bus module uses an IOMMU (shared by both
+ * PBMs of a controller, or per-PBM), and if a streaming buffer
+ * is present, each PCI bus module has it's own. (ie. the IOMMU
+ * might be shared between PBMs, the STC is never shared)
+ * Furthermore, each PCI bus module controls it's own autonomous
+ * PCI bus.
