 /** @file
-  GUID for use conveying the boot-state to PEI.
+  GUID and Name is used to configure PcdBootState to DynamicHii PCD, which can
+  make EDKII core work with EDK implementation.
 
+  EDK implementation may depend on this guid variable to check boot state. But 
+  EDKII core uses the dynamic PcdBootState to save boot state. To be compatible to EDK implementation, 
+  BootStateGuid and BootStateName will be used to configure PcdBootState to DynamicHii PCD to
+  save boot state as variable.
