I questioned myself about it many times. AFAIK, the rockpi4 without WiFi is ryf-certifiable. DisplayPort may need blobs, but USB-C is used only for power.It has blob free FLOSS drivers for the GPU and VPU. Its arm trusted firmware is fully open source.
So, yes it is possible to have a modern and affordable ryf-certified system.
- pabs3 5y agoI expect the USB-C chip has proprietary software running on it, since USB-C chargers have more computing power than the Apollo 11 Guidance Computer: https://forrestheller.com/Apollo-11-Computer-vs-USB-C-chargers.html https://forrestheller.com/Apollo-11-Computer-vs-USB-C-charge...
- marcodiego 5y agoFully ROM, secondary processor. Ryf-certifiable.
- pabs3 5y agoSoftware in ROM is worse, since you can't pull vendor updates to fix any security bugs and you can't reverse engineer it, produce free firmware and replace the proprietary firmware.
- marcodiego 5y agoAnd then we fall on the whole subject we're discussing here. In this particular case, a "power controller chip" I can even consider a fix or a change that improves efficiency... Nevertheless, I doubt most devices allow the update of a firmware for such a thing, in the end, it wouldn't make much of a difference. If the firmware is open source, sign me in! No opposition! Neither from me nor from the FSF. FSF would not oppose libre firmware. If it is not open source... well, then this is discussed in the other comments.
