This interface conveys state information out of the Security (SEC) phase into PEI.
This service is published by the SEC phase. The SEC phase handoff has an optional
EFI_PEI_PPI_DESCRIPTOR list as its final argument when control is passed from SEC into the
PEI Foundation. As such, if the platform supports the built-in self test (BIST) on IA-32 Intel
architecture or the PAL-A handoff state for Itanium architecture, this information is encapsulated
into the data structure abstracted by this service. This information is collected for the boot-strap
processor (BSP) on IA-32, and for Itanium architecture, it is available on all processors that execute
the PEI Foundation.
