Use the generic board detection method: - Board name: First compatible string from the device tree - Board model: Model property from the device tree Change occurrences of board name in userspace by the compatible string, and removed target specific board detection script Replace the definition of SUPPORTED_DEVICES in Device/Default to extract the dt compatible string from each device definition. Additionally, for devices supported by lede-17.01, append the value of BOARD_NAME to SUPPORTED_DEVICES in the device definition. Signed-off-by: Luis Araneda <luaraneda@gmail.com>
