+ S3 SMM Save State Protocol as defined in PI1.2 Specification VOLUME 5 Standard.
+
+ The EFI_S3_SMM_SAVE_STATE_PROTOCOL publishes the PI SMMboot script abstractions
+ On an S3 resume boot path the data stored via this protocol is replayed in the order it was stored.
+ The order of replay is the order either of the S3 Save State Protocol or S3 SMM Save State Protocol
+ Write() functions were called during the boot process. Insert(), Label(), and
+ Compare() operations are ordered relative other S3 SMM Save State Protocol write() operations
+ and the order relative to S3 State Save Write() operations is not defined. Due to these ordering
+ restrictions it is recommended that the S3 State Save Protocol be used during the DXE phase when
+ every possible.
+ The EFI_S3_SMM_SAVE_STATE_PROTOCOL can be called at runtime and
+ EFI_OUT_OF_RESOURCES may be returned from a runtime call. It is the responsibility of the
+ platform to ensure enough memory resource exists to save the system state. It is recommended that
+ runtime calls be minimized by the caller.
