-  Internal worker function that reports a status code through the Status Code Protocol

+  Internal worker function that reports a status code through the PEI Status Code Service or

+  OEM Hook Status Code Library.

 

-  This function checks to see if a Status Code Protocol is present in the handle

-  database.  If a Status Code Protocol is not present, then EFI_UNSUPPORTED is

-  returned.  If a Status Code Protocol is present, then it is cached in gStatusCode,

-  and the ReportStatusCode() service of the Status Code Protocol is called passing in

-  Type, Value, Instance, CallerId, and Data.  The result of this call is returned.

+  This function first tries to report status code via PEI Status Code Service. If the service

+  is not available, it then tries calling OEM Hook Status Code Library.

 

   @param  Type              Status code type.

   @param  Value             Status code value.
