Add a separate documentation directory for TEE subsystem since it is a standalone subsystem which already offers devices consumed by multiple different subsystem drivers. Split overall TEE subsystem documentation modularly where: - The userspace API has been moved to Documentation/userspace-api/tee.rst. - The driver API has been moved to Documentation/driver-api/tee.rst. - The first module covers the overview of TEE subsystem. - The further modules are dedicated to different TEE implementations like: - OP-TEE - AMD-TEE - and so on for future TEE implementation support.

TEE (Trusted Execution Environment)
|
|
===================================
|
|
|
|
This document describes the TEE subsystem in Linux.
|
|
|
|
Overview
|
|
========
|
|
|
|
A TEE is a trusted OS running in some secure environment, for example,
|
|
TrustZone on ARM CPUs, or a separate secure co-processor etc. A TEE driver
|
|
handles the details needed to communicate with the TEE.
|
|
|
|
This subsystem deals with:
|
|
|
|
- Registration of TEE drivers
|
|
|
|
- Managing shared memory between Linux and the TEE
|
|
|
|
- Providing a generic API to the TEE
