The goal of this patch series is to introduce TEE (Trusted Execution
Environment) interface support to AMD Secure Processor driver. The
TEE is a secure area of a processor which ensures that sensitive data
is stored, processed and protected in an isolated and trusted
environment. The Platform Security Processor (PSP) is a dedicated
processor which provides TEE to enable HW platform security. It offers
protection against software attacks generated in Rich Operating System
(Rich OS) such as Linux running on x86.

Based on the platform feature support, the PSP is capable of supporting
either SEV (Secure Encrypted Virtualization) and/or TEE. The first three
patches in this series is about moving SEV specific functions and data
structures from PSP device driver file to a dedicated SEV interface
driver file. The last two patches add TEE interface support to AMD
Secure Processor driver. This TEE interface will be used by AMD-TEE
driver to submit command buffers for processing in PSP Trusted Execution
Environment.

Rijo Thomas (5):
  crypto: ccp - rename psp-dev files to sev-dev
  crypto: ccp - create a generic psp-dev file
  crypto: ccp - move SEV vdata to a dedicated data structure
  crypto: ccp - add TEE support for Raven Ridge
  crypto: ccp - provide in-kernel API to submit TEE commands
