+// 19 7/24/13 6:15a Calvinchen
+// Bug Fixed: System hangs at CP60 if LastFfsFile Guild is installed with
+// DebugMode "ON".
+//
+// 18 5/22/13 7:30a Calvinchen
+// System hangs if OPTIMIZE_BOOT_FV_COPY = 1 with AMI Debug Rx enabled
+// Description : Added Saveing Module Type "EFI_FV_FILETYPE_DRIVER" in

+// [Category] Bug Fix
+// [Severity] Normal
+// [Symptom] PI 0.9 and 1.0 in Core 4.6.5.4
+// [RootCause] Build failed if PI 1.0.
+// [Files] PeiRamBoot.c
+//
+// 12 8/08/12 4:25a Calvinchen
+// 1. Changed for ReportFv2.c by Artem's suggestion.
+// 2. Fixed System hangs if Memory Mapping Changed with warm boot.

+// [TAG] EIP56322
+// [Category] Bug Fix
+// [Severity] Normal
+// [Symptom] System hangs after changing TPM settings in SETUP.
+// [RootCause] System Memory Mappings are changed with warm boot.
+// [Solution] BIOS always go cold boot path if system memory mappings
+// are changed

+// Bug Fixed : System hangs after reflashed BIOS with warm reset if
+// PEI_RAM_BOOT_S3_SUPPORT = 1 with fast warm boot support.
+//
+// 4 12/29/10 5:35a Calvinchen
+// Bug Fixed : DMI structure not update in system memory if
+// PEI_RAM_BOOT_S3_SUPPORT = 1 with fast warm boot support.
+//
+// 3 12/26/10 9:59p Calvinchen
+// Bug Fixed:
+// 1. Recovery not work if PEI_RAM_BOOT_S3_SUPPORT = 2.
+// 2. S4 resume failed if PEI_RAM_BOOT_S3_SUPPORT = 1 with fast warm boot
+// support.
+//
+// 2 12/14/10 2:25a Calvinchen
+// Improvement :
+// 1. Added an eLink "PeiRamBootList" for fast warm boot support
+// (PEI_RAM_BOOT_S3_SUPPORT = 1). If system boots in warm boot state, BIOS
+// directly boot to previous copied ROM image in RAM to save time of
+// copying ROM.
+// 2. Added "PEI_RAM_BOOT_S3_SUPPORT" = "2" for saving runtime memory, it
+// only keep necessary PEIM FFS in runtime memory for S3 resume
+// improvement.
+//
+// 1 10/27/10 2:48a Calvinchen
+// Initial Check-in.

+// Improvement :
+// 1. Added an eLink "PeiRamBootList" for fast warm boot support
+// (PEI_RAM_BOOT_S3_SUPPORT = 1). If system boots in warm boot state, BIOS
+// directly boot to previous copied ROM image in RAM to save time of

+// will not copy rom to ram in sequence boot, and, it could
+// cause system crashed. For avoiding this situation, BIOS
+// delete the PEI RAM Boot related variables if system executed
+// AFU.
