> CPUs aren't just beefy microcontrollers and they require some extra onchip hardware, but no one has done that yet for some reason For example, Graphics, Bluetooth, Wi-Fi, modem, are all heavily encumbered with patents. Very complex subsystems. Even components that have expired patents or no patents, such as an MMU, are non-trivial to create and take time. I suspect it'll take time before FOSS implementations appear.
