Module Name:
PciRootBridgeIo.h
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
