VOID EFIAPI SecPlatformDisableTemporaryMemory

(

VOID

)

This interface disables temporary memory in SEC Phase.

EFI_STATUS EFIAPI SecPlatformInformation	(	IN CONST EFI_PEI_SERVICES **	PeiServices,
		IN OUT UINT64 *	StructureSize,
		OUT EFI_SEC_PLATFORM_INFORMATION_RECORD *	PlatformInformationRecord
	)

This interface conveys state information out of the Security (SEC) phase into PEI.

Parameters

PeiServices	Pointer to the PEI Services Table.
StructureSize	Pointer to the variable describing size of the input buffer.
PlatformInformationRecord	Pointer to the EFI_SEC_PLATFORM_INFORMATION_RECORD.

Return values

EFI_SUCCESS	The data was successfully returned.
EFI_BUFFER_TOO_SMALL	The buffer was too small.

EFI_PEI_PPI_DESCRIPTOR* EFIAPI SecPlatformMain

(

IN OUT EFI_SEC_PEI_HAND_OFF *

SecCoreData

)

A developer supplied function to perform platform specific operations.

It's a developer supplied function to perform any operations appropriate to a given platform. It's invoked just before passing control to PEI core by SEC core. Platform developer may modify the SecCoreData passed to PEI Core. It returns a platform specific PPI list that platform wishes to pass to PEI core. The Generic SEC core module will merge this list to join the final list passed to PEI core.

Parameters

SecCoreData

The same parameter as passing to PEI core. It could be overridden by this function.

Returns

The platform specific PPI list to be passed to PEI core or NULL if there is no need of such platform specific PPI list.
