+ Provides the services required to access a block I/O device during PEI recovery
+ boot mode.
+
+ The Recovery Module PPI and the Device Recovery Module PPI are device neutral.
+ This PPI is device specific and addresses the most common form of recovery
+ media-block I/O devices such as legacy floppy, CD-ROM, or IDE devices.
+
+ The Recovery Block I/O PPI is used to access block devices. Because the Recovery
+ Block I/O PPIs that are provided by the PEI ATAPI driver and PEI legacy floppy
+ driver are the same, here we define a set of general PPIs for both drivers to use.
