Generating OE Machines based on Zephyr board definitions
========================================================
We currently have a recipe called generate-zephry-machines which will go through
and attempt to create an OE machine conf file for every board in Zephyr.
This is run via:
MACHINE=qemu-x86 bitbake generate-zephyr-machines
The output is then put in the normal deploy dir. This recipe is really only
useful for maintainers. There is currently no way to use the Zephyr board
definition in a single step build. So if you wish to regenerate those machines,
you will need to run the above, copy the conf files from the deploy dir to the
machine conf directory and then run your build. This shouldn't need to happen
often.
