2 This file declares Security Architectural PPI.\r
4a71b21a 3 \r
4 This PPI is installed by some platform PEIM that abstracts the security policy to the PEI\r
ac644614 5 Foundation, namely the case of a PEIM's authentication state being returned during the PEI section\r
4a71b21a 6 extraction process.\r
