A comment I recently made in email about the Arm-core RNGs:
The Arms are a real pain, lots of them have built-in RNGs but to access them
you need to be running in supervisor mode with all sorts of special control
bits and whatnot set, unlike the VIA and Intel user-mode-direct-read
mechanism. There isn't even any way of telling it's present, you have to
read the data sheet for each and every Arm core you might be running on and
hardcode the knowledge into your app. I played with it a few years ago and
gave up, without a special driver for every OS running on Arm it's basically
unusable.
