Factor the classes which do the work into a new "runner" package. This package has a core module where ZephyrBinaryRunner and common helpers will live, and one file per subclass / runner front-end. The top-level script, zephyr_flash_debug.py, still exists, but just delegates its work to the core. Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org>

"""Zephyr flash/debug script
|
|
|
|
This script is a transparent replacement for existing Zephyr flash and debug
|
|
scripts, i.e. scripts to flash binaries, run them, and debug them on real or
|
|
emulated hardware. If it can invoke the relevant tools natively, it will do so;
|
|
otherwise, it delegates to the shell script."""

|
# python zephyr_flash_debug.py openocd --openocd-bin=/openocd/path ...
|
|
#
|
|
# For now, maintain compatibility.
