2 | This file declares Security Architectural PPI.\r | |
3 | \r | |
4 | This PPI is installed by some platform PEIM that abstracts the security policy to the PEI\r | |
5 | Foundation, namely the case of a PEIM's authentication state being returned during the PEI section\r | |
6 | extraction process.\r | |
