Initial EB master slave on hardware: the aftermath

I did a little dry run implementation sending back and forth messages
in inside one FPGA for the last WR Dev workshop, reading and writing
and reading data to and from a PWM controller hooked up to some LEDs.
Now the current task remains to update everything to EB spec v 0.2,
clean up, do monte carlo testing and adapt to the network interface
of WR core. Integration work from both sides has just begun, so stay tuned
