OpenBSD Project doesn't have some problems with Texas Instrument? Why it's the best supported? Anyway, BBB require the load of a Masked ROM on pre-boot. This ROM have a closed source software. The PowerVR and the dedicated MPEG decoder is evil too. The OpenBSD port to ARM have aperture driver permission set or others ways to disable gpu/mpeg-dec, like Cedar A/V and Vivante?
