   2 // This driver produces UEFI PLATFORM_DRIVER_OVERRIDE_PROTOCOL if this protocol doesn't exist.
   3 //
   4 // It doesn't install again if this protocol exists.
   5 // It only implements one interface GetDriver of PLATFORM_DRIVER_OVERRIDE_PROTOCOL protocol
   6 // and doesn't support other two interfaces GetDriverPath, DriverLoaded.
   7 //
   8 // This driver also offers an UI interface in device manager to let user configure
   9 // platform override protocol to override the default algorithm for matching
  10 // drivers to controllers.
  11 //
  12 // The main flow:
  13 // 1. It dynamicly locate all controller device path.
  14 // 2. It dynamicly locate all drivers which support binding protocol.
  15 // 3. It export and dynamicly update two menu to let user select the
  16 // mapping between drivers to controllers.
  17 // 4. It save all the mapping info in NV variables for the following boot,
  18 // which will be consumed by GetDriver API of the produced the platform override protocol.
  19 //
  20 // Caution: This module is a sample implementation for the test purpose.
