; [TAG] EIP57440
; [Category] New Feature
; [Description] Add PI 1.1 SMM support for reading/writing floating
; point/smm save state.
;
; [Files] CpuCspLib.h, CpuCspLib.c, SmmPiSmst.c, SmmPrivateShared.h,
; SmmHdr.equ, SmmInit.c
;
; 25 8/11/09 11:46a Markw
; Removed Legacy registration. This is removed from latest PI and not
; used by projects.
;
; 24 7/08/09 8:09p Markw
; Update headers.
;
; 23 12/23/08 2:15p Markw
; EIP #17900 Set up TSS. Borland C in DOS hangs otherwise.
;
; 22 11/21/08 4:57p Markw
; Add SmmInit to SMM_ENTRY_STRUCT for SMM init for first normal/S3 boot.
; 32-bit CPU count.
;
; 21 9/07/08 12:42a Markw
; Separate SMM Private structure into inside SMM and outside SMM
; structure.
;
; 20 4/04/08 6:21p Markw
; Add Smrr MSR to SMM_BASE_PRIVATE_STRUCT.
;
; 19 3/03/08 6:35p Markw
; Added 32-bit register for smm thunk.
;
; 18 11/14/07 2:03p Markw
; Added SMRR support and updated SMM Cache for non-SMRR.
;
; 17 10/29/07 10:58a Markw
; Smm Thunk:
; * Code and data different segments.
; * Code position independent.
; * Switch for CSM for code and EBDA for data.
;
; 16 10/24/07 12:00p Markw
; SMM Thunk code position independent. Data in a separate segment than
; code in Smm Thunk.
;
; 15 9/10/07 1:39p Markw
; Add Interrupt Handling in SMM.
;
; 14 6/08/07 6:51p Markw
; Save/Restore XMM.
;
; 13 1/11/07 12:28p Markw
; Adjusted location of fields in structure for removal of legacy.
;
; 12 1/09/07 6:40p Markw
; Update BSP Entry Structure to remove dependencies on SMM_BSP_BASE.
;
; 11 12/29/06 4:45p Markw
; Add Smm Cache Support and update CPU syncronization.
;
; 10 12/21/06 5:19p Markw
; Remove old unused SmmStackSize from Private structure.
;
; 9 11/13/06 11:23a Markw

; 6 8/24/06 3:27p Felixp
; Preliminary x64 support (work in progress)
;
; 5 1/13/06 11:27a Markw
; Added SMM Thunk support.
;
; 4 1/10/06 2:56p Markw
; Add support for multi-threadding and sync all CPUs during entry/exit of
; SMM.
;
; 3 7/19/05 7:59p Markw
; Fixed smm base private header.
;
; 2 7/11/05 1:06p Markw
; Removed isCallback from structure.
