Makefile

#
# This is the main Makefile, which uses MicroPython build system,
# but Zephyr arch-specific toolchain and target-specific flags.
# This Makefile builds MicroPython as a library, and then calls
# recursively Makefile.zephyr to build complete application binary
# using Zephyr build system.
