# Instance of Platform Driver Override Library to manage driver overriding relationship.

# This library instance provides functions to manage the database of overriding relationship

# between controllers and drivers. Each entry of the database contains the mapping that Controller
|

# Device Path to a set of Driver Device Paths. The database is stored in non-volatile variables.
