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