#
# This is main Makefile, which uses MicroPython build system, but
# Zephyr arch-specific toolchain (setup by Zephyr's Makefile.toolchain.*).
# Unfortunately, it's currently not possible to get target (as in: specific
# board to run on) specific compile-time options from Zephyr, so these must
# be set (duplicated) in this Makefile. Currently, these configured for
# ARM Cortex-M3. This Makefile builds MicroPython as a library, and then
# calls recursively Makefile.zephyr to build complete application using
# Zephyr build system.
