+// 20    5/22/09 7:02p Felixp
+// Clean up of the IsCtrlHomePressed function
+// 
+// 18    5/22/09 6:08p Felixp
+// Core 4.6.3.6 support
+// 1. EIP 19921
+//    New hooks IsNvramDataCompatible and DxeIsNvramDataCompatible used by
+// NVRAM driver are added.
+//    NVRAM driver uses the hooks to checks compatibility of the current
+// NVRAM data 
+//    (mainly Setup-related variables) with the firmware code.
+// 2. IsRecovery function updated to return TRUE is the system is already
+// in Recovery mode.
+//    (this may happen if ROM corruption is detected in ReportFv.c)
+// 
+// 17    3/05/09 1:52p Felixp
+// Bug fix in IsMfgMode
+// Coments updated
+// 
+// 16    3/05/09 1:30p Felixp
+// Improvement EIP 18496:
+//   eLinks are exposed for the following porting functions defined in
+// OemPort:
+//     IsRecovery, NoConfigChanges, IsMfgMode, IsResetConfigMode,
+// IsDefaultConfigMode
+// 
+// 15    1/30/09 1:33p Felixp
+// Updated to comply with Core 4.6.3.5.
+// Improvement. EIP 18483. 
+// Interface of the hooks that detect NVRAM operational mode is extended.
+// NVRAM driver uses platform hooks(IsMfgMode, IsResetConfigMode,
+// IsDefaultConfigMode) 
+// defined in this file to detect, which set of configuration values are
+// to be used. 
+// In some cases the mode is detected based on value of the NVRAM
+// variable.
+// Interface of the hook functions is extended. New parameter is added. 
+// Pointer to EFI_PEI_READ_ONLY_VARIABLE2_PPI PPI is passed to the hook
+// functions. 
+// The pointer can be used to read and enumerate existing NVRAM variables.
+// 
+// 14    9/06/07 1:24a Felixp
+//  - New porting hooks used by Core 4.6.2 NVRAM code added
+//  - Clean up
+// 
+// 13    1/11/07 1:07p Anandakrishnanl
+//  Keyboard decode enabling for Recovery support in 64 bit 
+// 
+// 12    10/16/06 11:52a Fredericko
+// Fix logic error with checking for keypress status
+// 
+// 11    6/13/06 5:00p Sivagarn
+// - Updated file header
+// - Updated format
+// 
+// 10    5/09/06 4:57a Sangeethav
+// - Cntrl+Home support included.
+// 
+// 7     11/07/05 6:56p Felixp
+// Jumber Recovery support added
+// 
+// 6     11/07/05 6:14p Markw
+// Added recovery checking.
+// 
+// 5     7/18/05 6:24p Davidd
+// Removed the CPU, System Slot, and On-Board Device porting hooks for
+// SMBIOS. (They were moved to new porting file SmbiosBoard.c).
+// 
+// 3     7/13/05 5:33p Davidd
+// Added sample code to create dynamic CPU data for SMBIOS.
+// 
+// 2     7/05/05 11:52a Davidd
+// Added porting functions for SMBIOS.
