+// Revision History
+// ----------------
+// $Log: /Alaska/BIN/Core/Modules/BoardInfo/AmiBoardInfo.c $
+//
+// 7 12/16/11 5:02p Yakovlevs
+// Added functions headers for CHM
+//
+// 6 9/30/11 5:40p Yakovlevs
+// [TAG] EIP66222
+// [Category] New Feature
+// [Description] Modify PCI bus driver to get board info from separate
+// FFS section
+// [Files] AmiBoaardInfo.c;
+// AmiBoaardInfo.mak;
+// AmiBoaardInfo.sdl;
+// PciBoard.c
+// AmiBoaardInfo.h
+//
+// 5 6/28/11 5:51p Yakovlevs
+// [TAG] EIP 60123
+// [Category] Bug Fix
+// [Severity] Important
+// [Symptom] Resource padding is not functional for PCIe hot-plug.
+// [RootCause] In HP Mode #ifndef statement was not working
+// [Solution] Cahnged to reference AMI_HOTPLUG_INIT_SUPPORT token
+// [Files] AmiBoardInfo.c PciBoard.c
+//
+// 4 3/01/10 5:06p Yakovlevs
+// New separate Label with generic Multi-Root support.
+// Uses new AMI SDL "C" sytle output for the former "ASM" style.
+//
+// 3 5/05/09 3:16p Felixp
+// Disable ACPI module dependent code if ACPI_MODULE_VER is less or equal
+// than 30
+//
+// 2 5/05/09 1:07p Felixp
+// Formatting update: File headers are updated.
+//
+// 1 4/28/09 1:20p Yakovlevs
+// Added new ModulePart - Ami Board Info.
+// This module groups together all VeB generated outpit files as well as
+// DSDT generation.
