+  @param  PeiServices      An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
+  @param  CodeType         Indicates the type of status code being reported.
+  @param  Value            Describes the current status of a hardware or
+                           software entity. This includes information about the class and
+                           subclass that is used to classify the entity as well as an operation.
+                           For progress codes, the operation is the current activity.
+                           For error codes, it is the exception.For debug codes,it is not defined at this time.
+  @param  Instance         The enumeration of a hardware or software entity within
+                           the system. A system may contain multiple entities that match a class/subclass
+                           pairing. The instance differentiates between them. An instance of 0 indicates
+                           that instance information is unavailable, not meaningful, or not relevant.
+                           Valid instance numbers start with 1.
+  @param  CallerId         This optional parameter may be used to identify the caller.
+                           This parameter allows the status code driver to apply different rules to
+                           different callers.
