#
# 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.
