Hello,
The problem with the "all" implementation is that it hogs the ARM/DSP
heavily and that's the reason why we specifically avoided this in our
firmware design.
Hence, implementing this condition spoils the whole purpose of the PRU!!

I'd really like to see that you add a "all" implementation to the
firmware. Or even better use the standard id/mask approach.
cheers, Marc
