Sebastian Bøe d6de4c7a99 cmake: Fall back to ZEPHYR_BASE when the board is not in BOARD_ROOT ... It is very inconvenient to maintain an application that both runs on a Zephyr board and an out-of-tree board. It forces one to write build scripts like this in the app: if(BOARD STREQUAL my_out_of_tree_board) set(BOARD_ROOT some/out/of/tree/board/path) endif() To avoid this we change the semantics of BOARD_ROOT. Instead of it being a path to the board root it is now a prioritized list of board root directories. Zephyr will append ZEPHYR_BASE to BOARD_ROOT. This ensures that Zephyr boards can be used when the out-of-tree board directory can not supply the requested board.
