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

142 This interface conveys state information out of the Security (SEC) phase into PEI.
144 This service is published by the SEC phase. The SEC phase handoff has an optional
145 EFI_PEI_PPI_DESCRIPTOR list as its final argument when control is passed from SEC into the
146 PEI Foundation. As such, if the platform supports the built-in self test (BIST) on IA-32 Intel
147 architecture or the PAL-A handoff state for Itanium architecture, this information is encapsulated
148 into the data structure abstracted by this service. This information is collected for the boot-strap
149 processor (BSP) on IA-32. For Itanium architecture, it is available on all processors that execute
152 @param PeiServices The pointer to the PEI Services Table.
153 @param StructureSize The pointer to the variable describing size of the input buffer.
154 @param PlatformInformationRecord The pointer to the EFI_SEC_PLATFORM_INFORMATION_RECORD.
156 @retval EFI_SUCCESS The data was successfully returned.
157 @retval EFI_BUFFER_TOO_SMALL The buffer was too small. The current buffer size needed to
158 hold the record is returned in StructureSize.
