The PSP (Platform Security Processor) provides support for key management commands in Secure Encrypted Virtualization (SEV) mode, along with software-based Trusted Execution Environment (TEE) to enable third-party Trusted Applications. Therefore, introduce psp-dev.c and psp-dev.h files, which can invoke SEV (or TEE) initialization based on platform feature support. TEE interface support will be introduced in a later patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
