  This file declares Sec Platform Information PPI.\r
\r
  This service is the primary handoff state into the PEI Foundation. \r
  The Security (SEC) component creates the early, transitory memory \r
  environment and also encapsulates knowledge of at least the \r
  location of the Boot Firmware Volume (BFV).\r
