Agreed. I don't know how feasible in that yet, but would like to know
Florian's thoughts/requirements to give it a thought. I don't think you
are missing anything. One thing I thought is to add SMCCC version as well
if we are adding PSCI version as lots of new additions have happened
and it is good to have info IMO. SMCCC_ARCH_FEATURES query APIs might be
useful. This is just initial thoughts.
