/** @file\r
  This file declares the Device Recovery Module PPI.\r
\r
  The interface of this PPI does the following:\r
    - Reports the number of recovery DXE capsules that exist on the associated device(s)\r
    - Finds the requested firmware binary capsule\r
    - Loads that capsule into memory\r
\r
  A device can be either a group of devices, such as a block device, or an individual device.\r
  The module determines the internal search order, with capsule number 1 as the highest load\r
  priority and number N as the lowest priority.\r
