/** @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
