	  Features added into FSP 2.2 specification that impact coreboot are:
	  1. Added multi-phase silicon initialization to increase the modularity of the
	      FspSiliconInit() API
	  2. FSP_INFO_HEADER changes to add FspMultiPhaseSiInitEntryOffset
	  3. Added EnableMultiPhaseSiliconInit, bootloaders designed for FSP2.0/2.1 can disable
	      the FspMultiPhaseSiInit() API and continue to use FspSiliconInit() without change.

	  Enable support for fsp to use same stack as coreboot.

	  This hash needs to be updated every time recovery mode training
	  is recomputed, or if the hash does not match recovery MRC cache.
	  Selecting this option requires that TPM already be setup by this
	  point in time.  Thus it is only compatible when the option
	  VBOOT_STARTS_IN_BOOTBLOCK is selected, which causes verstage and
	  TPM setup to occur prior to memory initialization.
