[Arm-netbook] AMD considering releasing the PSP

[Bill Kontos]

One can argue of going the signed firmware route for security is a good or
a bad practice and I agree with you that the unbrickable design of the A20
is a better one, but that is irrelevant in the case of Ryzen chips: They
have already been taped out so we have to work with what we are given.
Going completely free with risc v would be cool but that is years away.
