+    <Description>PCI bus driver. This module will probe all PCI devices and allocate MMIO and IO
+       space for these devices.
+       LightPcdLib.c tagged with "ToolCode="DUMMY"" is light weight verison for PCI library
+       function. This version provide simple implementation and do not support hot plug. Only one
+       between PcdLib.c and LightPcdLib.c can be choosed.
