<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! Florentin

After glancing thru this PSP (Platitude Spewing Presentation), it looks more like they are grafting the security model of ARM-based SoCs onto x86 where a masked ROM loads the next stage.
A couple kind of nice things they mention:
- "Isolated on-chip ROM and SRAM" - So this may be somewhat more constrained
than the multi-megabyte blobs for MEs?
- "Secure Boot does not require the system ROM image to be signed"
Not so nice: "Access to system memory / resources". Ugh.
well, we all know how well that's worked fro the ME.
so, another insecure x86 platform. Great.
