AMD advertises that it supports a Trusted Execution Environment (TEE), which runs on the AMD Secure Processor (ASP), formerly known as the AMD Platform Security Processor (PSP). AMD also publishes a driver for the ASP/PSP, and this driver supports loading Trusted Applications (TAs).
I understand that AMD-based BIOSes include Trusted Applications to implement things like DRTM, fTPM, S0i3, and SEV.
My question is, does AMD support loading third-party Trusted Applications? If so, does anyone know of any third-party applications that load their own TA? I'm thinking third-party TAs would be useful for banking/payment applications or content streaming apps that use hardware-based DRM (for example Widevine L1). I just can't seem to find any AMD-published information about developing Trusted Applications. A related question is, does AMD publish any Trusted Applications of their own besides SEV?
