Unit testing is also possible

Kind regards

Are you interested in adding this to the official symbol and footprint collection?

1. Check if the TPM is available:
   # cat /sys/class/misc/hw_random/rng_available
   The output should look like this:

Your supplied examples contain NO comments!
Please add copious comments explaining exactly what you are doing and why.
