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