   2   Status Code Architectural Protocol implementation as defined in Tiano
   3   Architecture Specification.
   4
   5   This driver has limited functionality at runtime and will not log to Data Hub
   6   at runtime.
   7
   8   Notes:
   9   This driver assumes the following ReportStatusCode strategy:
  10   PEI       -> uses PeiReportStatusCode
  11   DXE IPL   -> uses PeiReportStatusCode
  12   early DXE -> uses PeiReportStatusCode via HOB
  13   DXE       -> This driver
  14   RT        -> This driver
