// $Log: /Alaska/SOURCE/Modules/Intel Fast Flash Standby/iRST_SharkBay/RapidStartWrapper/RapidStartWrapperSmm.c $
//
// 3 5/13/14 4:56a Joshchou
// [TAG] EIP167032
// [Category] Improvement
// [Description] Review the variable's attribute, we shouldn't use
// runtime attribute with setup variable.
// [Files] RapidStartWrapperSmm.c
// RapidStartWrapperSmm.h
// RapidStartWrapperSmm.cif
//
// 2 4/15/13 2:36a Bensonlai
// [TAG] None
// [Category] Bug Fix
// [Severity] Important
// [Symptom] If users change any item from driver then restore to boot
// setting, our SMI can't distinguish between user's and driver's event.
// [RootCause] It's an Intel driver issue.
// [Solution] 1. Removing the sync up with Rapid Start driver and BIOS
// variable as default.
// 2. Remove our BIOS workaround.
// [Files] RapidStartWrapperSmm.sdl, RapidStartWrapperSmm.h,
// RapidStartWrapperSmm.sdl, RapidStartWrapperAcpiTables.sdl,
// RapidStartWrapper.sdl
//
// 1 12/27/12 2:23a Bensonlai
// [TAG] EIP110680
// [Category] New Feature
// [Description] When iRST application is run under OS, and change
// timer.
// BIOS should update the changed to Setup option as well.
