+ PlatOverMngr.c
+
+Abstract:
+
+ A UI driver to offer a UI interface in device manager to let user configue
+ platform override protocol to override the default algorithm for matching
+ drivers to controllers.
+
+ The main flow:
+ 1. The UI driver dynamicly locate all controller device path.
+ 2. The UI driver dynamicly locate all drivers which support binding protocol.
+ 3. The UI driver export and dynamicly update two menu to let user select the
+ mapping between drivers to controllers.
+ 4. The UI driver save all the mapping info in NV variables which will be consumed
+ by platform override protocol driver to publish the platform override protocol.
