Chris Morgan ff27afedff board: rockchip: Add panel auto-detection for Anbernic RGxx3 ... Add support to automatically detect the panel for the Anbernic RGxx3. This is done by creating a "pseudo driver" that provides only the bare minimum to start the DSI controller and DSI DPHY. Once started, we then can query the panel for its panel ID and compare it to a table of known values. The panel compatible string (which corresponds to the upstream Linux driver) is then defined as an environment variable "panel". The panel compatible string is also changed automatically via an ft_board_setup() call if what is detected differs from what is in the loaded tree. This way, end users can use the same bootloader without having to worry about which panel they have (as there is no obvious way of knowing).
