This service of the EFI_PEI_TEMPORARY_RAM_SUPPORT_PPI that migrates temporary RAM into permanent memory.

Parameters

PeiServices	Pointer to the PEI Services Table.
TemporaryMemoryBase	Source Address in temporary memory from which the SEC or PEIM will copy the Temporary RAM contents.
PermanentMemoryBase	Destination Address in permanent memory into which the SEC or PEIM will copy the Temporary RAM contents.
CopySize	Amount of memory to migrate from temporary to permanent memory.

Return values

EFI_SUCCESS	The data was successfully returned.
EFI_INVALID_PARAMETER	PermanentMemoryBase + CopySize > TemporaryMemoryBase when TemporaryMemoryBase > PermanentMemoryBase.
