+/** @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
