-/** @file

-

-  A UI application to offer a UI interface in device manager to let user configure

-  platform override protocol to override the default algorithm for matching

-  drivers to controllers.

-

-  The main flow:

-  1. The UI application dynamicly locate all controller device path.

-  2. The UI application dynamicly locate all drivers which support binding protocol.

-  3. The UI application export and dynamicly update two menu to let user select the

-     mapping between drivers to controllers.

-  4. The UI application save all the mapping info in NV variables which will be consumed

-     by platform override protocol driver to publish the platform override protocol.

-#  A UI application to offer an UI interface in device manager to let user configure

-#  The main flow:

-#  1. The UI application dynamicly locate all controller device path.

-#  2. The UI application dynamicly locate all drivers which support binding protocol.

-#  3. The UI application export and dynamicly update two menu to let user select the

-#  4. The UI application save all the mapping info in NV variables for the following boot, 

-#     which will be consumed by platform override protocol driver to publish the platform override protocol.
