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