Design: FirmwareBartender

Buildflow

The FirmwareBartender

Evaluates which firmwares have to be compiled
Orders the firmware for priority
If required: Calls git clone/checkout
If required: Calls git clean
Builds one firmware after the other * Informs TestBartender about the firmwares which have become ready

Multiprocessing

The firmware shall be built while tests are running.

Therefore, the FirmwareBartender delegates the build to a subprocesses.
