It would be fair to mention that TrustZone, the equivalent technology, is built into the cores/ISA. They also do distribute software related to the TrustZone, albeit not a full TEE solution.
TrustZone is not an equivalent technology to ME/PSP. TrustZone is a technology for providing hardware isolation and ME/PSP are co-processors that manage the entire CPU socket (the Ryzens and the i9s)
