# 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.

#
zephyr: Move "minimal" configuration building to a separate wrapper script. Minimal config can be now build with: ./make-minimal BOARD=... This is required because of Makefile.exports magic, which in its turn depends on PROJ_CONF to be set correctly at the beginning of Makefile parsing at all times. Instead of adding more and more workarounds for that, it's better to just move minimal support to a separate wrapper. Also, remove Zephyr 1.5 era cruft from Makefile, and add support for Zephyr's "run" target which supercedes older "qemu" target in upstream.

zephyr: Use recently added "make outputexports" Zephyr target. The outputexpors target, which exports Zephyr environment variables, was recently added to Zephyr.

zephyr/modzephyr: Add a module for Zephyr-specific things. Mostly intended to ease experimentation, no particular plans for APIs so far (far less their stability), is_preempt_thread() provided is mostly an example.

modzephyr.c \
zephyr: Initial implementation of machine.Pin. The integration with Zephyr is fairly clean but as MicroPython Hardware API requires pin ID to be a single value, but Zephyr operates GPIO in terms of ports and pins, not just pins, a "hierarchical" ID is required, using tuple of (port, pin). Port is a string, effectively a device name of a GPIO port, per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer number of pin with the port (supposed to be in range 0-31). Example of pin initialization: pin = Pin(("GPIO_1", 21), Pin.OUT) (an LED on FRDM-K64F's Port B, Pin 21). There is support for in/out pins and pull up/pull down but currently there is no interrupt support.

prj.conf: prj_base.conf
zephyr: Make sure that generated prj.conf is updated only on content changes. This is a typical problem with make: we want to trigger rebuilds only if file actually changed, not if its timestamp changed. In this case, it's aggravated by the fact that prj.conf depends on the value of BOARD variable, so we need to do some tricks anyway. We still don't try to detect if just BOARD changed, just try to generate new prj.conf.tmp every time (quick), but do actual replacement of prj.conf only if its content changed.
