I think POWER is open source now? i.e. https://www.nextplatform.com/2019/08/20/big-blue-open-sources-power-chip-instruction-set/
But nothing on the mobile front. I am glad we have some promise on the horizon. Looking forward to getting a RISCV, etc computer one day.
Thanks for sharing! I can’t wait to see how this unfolds. I agree with @uiizi@lemmy.ml that now would be a good time for coreboot and neutered ME. Also hoping for a more open source alternatives for the long term (RISCV, POWER, etc).
