The Radxa ZERO 3W/3E is an ultra-small, high-performance single board computer based on the Rockchip RK3566, with a compact form factor and rich interfaces.
Implement rk_board_late_init() to set correct fdtfile env var and board_fit_config_name_match() to load correct FIT config based on what board is detected at runtime so a single board target can be used for both board models.
