-# Module Name:
-#
-# SecEntry.S
-#
-# Abstract:
-#
-# This is the code that goes from real-mode to protected mode.
-# It consumes the reset vector, calls TempRamInit API from FSP binary.

-#----------------------------------------------------------------------------
-#
-# Procedure: _ModuleEntryPoint
-#
-# Input: None
-#
-# Output: None
-#
-# Destroys: Assume all registers
-#
-# Description:
-#
-# Transition to non-paged flat-model protected mode from a
-# hard-coded GDT that provides exactly two descriptors.
-# This is a bare bones transition to protected mode only
-# used for a while in PEI and possibly DXE.
-#
-# After enabling protected mode, a far jump is executed to
-# transfer to PEI using the newly loaded GDT.
-#
-# Return: None
-#
-# MMX Usage:
-# MM0 = BIST State
-# MM5 = Save time-stamp counter value high32bit
-# MM6 = Save time-stamp counter value low32bit.
