Actually, I think things like this mostly have been missing
because manufacturers didn't understand they were important. Even
the Raspberry Pi now has an SoC with a hardware RNG.
In addition to getting CPU makers to always include such things,
however, a second vital problem is how to gain trust that such RNGs
are good -- both that a particular unit isn't subject to a hardware
defect and that the design wasn't sabotaged. That's harder to do.
