Defines two environment variables for use in producing DTB file names, among other uses:
imx_type: defines the CPU variant through the get_imx_type() routine board_name: environment variable equivalent of CONFIG_SYS_BOARD_NAME Both can be over-ridden by a user. This is expected to be most useful when transitioning to a custom board.
