For of/devicetree using machines, set the board_type used for nvram file selection to the first string listed in the top-level's node compatible string, aka the machine-compatible as used by of_machine_is_compatible(). The board_type setting is used to load the board-specific nvram file with a board-specific name so that we can ship files for each supported board in linux-firmware.
