2 Status Code Architectural Protocol implementation as defined in Tiano
3 Architecture Specification.

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
