/** @file\r
  This module produce main entry for BDS phase - BdsEntry.\r
  When this module was dispatched by DxeCore, gEfiBdsArchProtocolGuid will be installed\r
  which contains interface of BdsEntry.\r
  After DxeCore finish DXE phase, gEfiBdsArchProtocolGuid->BdsEntry will be invoked\r
  to enter BDS phase.\r
