scripts: runner: use arguments, not environment vars The various runners (flash/debug scripts) use environment variables to take arguments. This is legacy behavior which is not desirable. Use command line arguments instead. Note: this leaves more general environment variables with publicly documented behavior in place for now, for compatibility, e.g.: ZEPHYR_FLASH_OVER_DFU, OPENSDA_FW, ESP_IDF_PATH, PYOCD_DAPARG For example, when using dfu-util to flash arduino_101, instead of setting DFUUTIL_PID, DFUUTIL_ALT, and DFUUTIL_IMG environment variables, have the script invocation look like this: python3 .../zephyr_flash_debug.py dfu-util flash \ [common arguments omitted] \ --pid=8087:0aba --alt=x86_app \ --img=.../build/zephyr/zephyr.bin Make similar changes for other runners (openocd, etc.) and targets (debug, debugserver). To implement this in the scripts: - have the individual scripts/support/runner/some-runner.py files register their own command line arguments - teach them to construct instances from arguments, not the environment - have zephyr_flash_debug.py request runners to register command line argument parsers, and handle arguments In the build system: - add a new board_runner_args() extension function that board.cmake files can use to add to the zephyr_flash_debug.py command line - adjust cmake/flash/CMakeLists.txt to invoke with arguments - add new helper include files for each runner (like boards/common/dfu-util.board.cmake, etc.), which add default options as needed and then add on overrides from board_runner_args() calls - update board.cmake files to use the new includes and extension This implied some tweaking when using openocd to make the CMake string escaping and unescaping work properly.
