   2   This file defines a configuration Table Guid for Load module at fixed address.
   3
   4   This configuration table is to hold  the top address below which the Dxe runtime code and
   5   boot time code will be loaded and Tseg base. When this feature is enabled, Build tools will assigned
   6   module loading address relative to these two addresses.
