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