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.

asking for a full unconditional release of everything including releasing the signed keys for loading firmware( that doesn't make any sense, if you have a system that needs a signed key but the key is public what's the

exactly: the point is, they should never have added secret-key firmware signing into the hardware in the first place. *that's* the point.
press coverage they wanted). So don't get your hopes too high on this.
yep. which is why i'm recommending they go "clean slate" and go with RISC-V with x86 part-acceleration. i looked at the numbers from a 2015 paper on the FP implementation in rocket: it's a whopping 40% more power-efficient for the same performance.
