Is there any source that mentions the AMD PSP will be on the Ryzen CPU series (the FAQ says everything 16h +) . I wasn't able to find anything confirming that so far.

According to this page (footnote) from AMD it looks like the PSP won't be on the current Ryzen cpu line .

Footnote: AMD Secure Processor (formerly “Platform Security Processor” or “PSP”) is a dedicated processor that features ARM TrustZone® technology, along with a software-based Trusted Execution Environment (TEE) designed to enable third-party trusted applications. AMD Secure Processor is a hardware-based technology which enables secure boot up from BIOS level into the TEE. Trusted third-party applications are able to leverage industry-standard APIs to take advantage of the TEE’s secure execution environment. Not all applications utilize the TEE’s security features. AMD Secure Processor is currently only available on select AMD A-Series and AMD E-Series APUs.

Also the product information pages for the Ryzen hardware don't mention the PSP

While products with the PSP (that I checked) have it mentioned on their product page:

It is my understanding modern AMD chips at least have other freedom issues; see the recent announcements.
