◆ PeiCore()

VOID EFIAPI PeiCore	(	IN CONST EFI_SEC_PEI_HAND_OFF *	SecCoreDataPtr,
		IN CONST EFI_PEI_PPI_DESCRIPTOR *	PpiList,
		IN VOID *	Data
	)

This routine is invoked by main entry of PeiMain module during transition from SEC to PEI. After switching stack in the PEI core, it will restart with the old core data.

Parameters

SecCoreDataPtr	Points to a data structure containing information about the PEI core's operating environment, such as the size and location of temporary RAM, the stack location and the BFV location.
PpiList	Points to a list of one or more PPI descriptors to be installed initially by the PEI core. An empty PPI list consists of a single descriptor with the end-tag EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST. As part of its initialization phase, the PEI Foundation will add these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any modules can leverage the associated service calls and/or code in these early PPIs
Data	Pointer to old core data that is used to initialize the core's data areas. If NULL, it is first PeiCore entering.
