+/** @file
+  An event group GUID with which BDS indicates that PCI root bridges have been
+  connected, and PciIo protocol instances have become available.
+
+  Note that this differs from the PCI Enumeration Complete Protocol as defined
+  in the PI 1.1 specification. That protocol is installed by the PCI bus driver
+  after enumeration and resource allocation have been completed, but before
+  PciIo protocol instances are created.
