+# PCI Library that layers on top of the SMM PCI Root Bridge I/O Protocol.
+#
+# This library produces the APIs from the PCI Library and implements these APIs
+#  by calling into SMM PCI Root Bridge I/O Protocol. SMM PCI Root Bridge I/O Protocol is
+#  typically produced by a chipset specific SMM driver.
+#  This library binds to the first SMM PCI Root Bridge I/O Protocol in the platform. As a result,
+#  it should only be used on platforms that contain a single PCI root bridge.
