/** @file
Status Code Architectural Protocol implementation as defined in Tiano
Architecture Specification.
This driver has limited functionality at runtime and will not log to Data Hub
at runtime.
Notes:
This driver assumes the following ReportStatusCode strategy:
PEI -> uses PeiReportStatusCode
DXE IPL -> uses PeiReportStatusCode
early DXE -> uses PeiReportStatusCode via HOB
DXE -> This driver
RT -> This driver
