As far as I know, AMD does not have any "evil brother" of Intel ME. It only has AMD PSP (Platform Secure Processor) that is built-in to CPU. So, I don't think that cutting a PCH from AMD CPU has any practical value: even if the platform will boot after such a radical change to computer's hardware, you'll lose a lot of essential stuff like USB ports

Hello Coreboot folks,

I have couple of interesting questions here.

Recently, I have started learning about AMD (RYZen did not live me unemotional), so after reading several articles (especially one with AMD architecture):
http://www.anandtech.com/show/11182/how-to-get-ryzen-working-on-windows-7-x64

I found/got from this article very interesting thought: AMD's APU, as shown on this picture, could be left alone, even not connecting Chipset/PCH!?

I know that for INTEL this is impossible to do. With early INTEL ME involvement to HW bring up (wrt PMIC and EC), I am wondering if this is very similar architecture with AMD?

Inline image 1

[1] Did anybody try some proprietary embedded design, with AMD's APU all alone (is it at all possible)?
[2] if [1] true, does anybody have some HW schema showing in details how this is done/designed?
[3] if [1] is true. does Coreboot support such AMD designs (sans chipsets/PCHs)?

Thank you,
Zoran
