+  Provides services to log the SMI handler registration.\r
+\r
+  This API provides services for the SMM Child Dispatch Protocols provider,\r
+  to register SMI handler information to SmmCore.\r
+\r
+  NOTE:\r
+  There is no need to update the consumers of SMST->SmiHandlerRegister() or\r
+  the consumers of SMM Child Dispatch Protocols.\r
+  The SmmCore (who produces SMST) should have ability to register such\r
+  information directly.\r
+  The SmmChildDispatcher (who produces SMM Child Dispatch Protocols) should\r
+  be responsible to call the services to register information to SMM Core.\r
