// Revision History
// ----------------
// $Log: /Alaska/SOURCE/Core/EDK/DxeMain/AmiDxeInit.c $
//
// 24 5/05/11 3:47p Artems
// Added DevicePathToText and DevicePathFromText protocols
//
// 23 2/05/11 4:09p Artems
// EDK library functions CopyMem and ZeroMem moved to EdkLib.c
//
// 22 9/29/10 8:05a Felixp
// Enhancement: Initialization of the library TheImageHandle variable is
// added.
//
// 21 4/22/10 10:43p Felixp
// Install dummy instance of the security protocol when
// INSTALL_DUMMY_SECURITY_PROTOCOL SDL token is set to "on".
//
// 20 2/23/10 10:01p Felixp
// Updated to use CORE_COMBINED_VERSION token.
//
// 19 11/13/09 4:31p Felixp
// Buffer overflow protection is added (calls to Sprintf replaced with
// Sprintf_s).
//
// 18 7/30/09 4:04p Felixp
// Bug fix:
// Symptoms: memory corruption during DXE Core initialization.
// Details: the corruption was caused by the HOBs created in AmiDxeInit1.
// The HOB creation moved to an earlier point (before HOB data is used by
// CoreInitializeMemoryServices).
//
// 17 5/04/09 3:10p Felixp
// Creation of CPU HOB moved from AmiPeiInit.c to AmiDxeInit.c
//
// 16 3/05/09 4:39p Oleksiyy
// EIP 18486: 3 GUID EXTENSION HOBs created.
// Code clean up performed.
//
// 15 4/18/08 6:28p Felixp
// checkpoint(0x60) removed. Corresponsing status code (DXE_CORE_ENTRY is
// now reported at the and of DXE IPL using status code infrastructure
//
// 14 3/12/08 12:44p Felixp
// Progress/Error codes reporting added
//
// 13 2/21/08 5:05p Felixp
// FirmwareRevision field of the EFI system table is updated to use
// CORE_BUILD_NUMBER.
//
// 12 9/05/07 4:22p Felixp
// FirmwareVendor field of the EFI_SYSTEM_TABLE was initialized with a
// pointer to boot time memory. However, this is a runtime field.
// File updated to allocate runtime memory for the field.
//
// 11 10/12/06 9:43p Felixp
//
// 10 10/12/06 6:51p Felixp
// UEFI2.0 support: DevicePathUtilities protocol added
//
// 9 10/07/06 10:24a Felixp
// UIEFI2.0 support.
// Updated to EDK 20060904
//
// 8 8/24/06 10:11a Felixp
// x64 support: warning/error fixes
//
// 7 5/23/06 4:16a Felixp
//
// 6 5/22/06 11:57a Felixp
//
// 5 5/22/06 12:12a Felixp
// Vendor & Revision fields of ST initialized
//
// 4 5/20/06 9:37p Felixp
// checkpoint 0x60 added
// debug message for drivers startting/stopping
// clean up
//
// 3 5/19/06 10:46p Felixp
