[coreboot] Re : Re: AMD PSP

<TROLL> So we can kiss goodbye coreboot on AMD platforms in the future?.. How sad! :-/ </TROLL>
Does this thing "Platform Security Processor" exist in any AMD CPUs buyable today (Q3 2014) or it will  begin to be implemented later?
Thank you for this information!

well, we all know how well that's worked fro the ME.

so, another insecure x86 platform. Great.
