+
+Abstract:
+
+ PCI Root Bridge I/O protocol as defined in the EFI 1.1 specification.
+
+ PCI Root Bridge I/O protocol is used by PCI Bus Driver to perform PCI Memory, PCI I/O,
+ and PCI Configuration cycles on a PCI Root Bridge. It also provides services to perform
+ defferent types of bus mastering DMA
