Adds AMD-TEE driver. * targets AMD APUs which has AMD Secure Processor with software-based Trusted Execution Environment (TEE) support * registers with TEE subsystem * defines tee_driver_ops function callbacks * kernel allocated memory is used as shared memory between normal world and secure world. * acts as REE (Rich Execution Environment) communication agent, which uses the services of AMD Secure Processor driver to submit commands for processing in TEE environment Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Tom Lendacky <thomas.lendacky@amd.com> Acked-by: Jens Wiklander <jens.wiklander@linaro.org> Co-developed-by: Devaraj Rangasamy <Devaraj.Rangasamy@amd.com> Signed-off-by: Devaraj Rangasamy <Devaraj.Rangasamy@amd.com> Signed-off-by: Rijo Thomas <Rijo-john.Thomas@amd.com> Reviewed-by: Gary R Hook <gary.hook@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
