Hello again, bridgman.
Thank you very much for your added tips and explanations.
You are right, about it being incorrect for me to put Intel's ME and AMD's PSP in the same bag... I was lead to a mistake, because of having first read about Intel's ME... Because Intel's ME is located in the motherboard itself (in the "Controller Hubs"), when I first read about AMD's (I guess, sort of) equivalent, being the first sentence that describes the "Platform Security Processor (PSP)" in libreboot's website one that says "This is basically AMD’s own version of the Intel Management Engine", when I first read that the PSP is "built onto the main CPU die", I wrongly assumed that the "CPU die" was also a part of the motherboard itself (I thought that it was the part of the CPU socket circuitry that made direct contact with the CPU.) But, I've just checked, and a "CPU die" is a part of the CPU itself... (I'm sorry, I'm not a native English speaker, nor any sort of computer specialist, and should have checked the meaning of "die".) So, as you say, it really is quite a different implementation of the same sort of "principle". (The reason why I "lump PSP and ME together", is because I see them both as very serious security risks, for being "hidden" places where someone can implement Trojan horses and such, that can operate unseen from the operating system.)
