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