charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-riscv" Errors-To: linux-riscv-bounces+linux-riscv=archiver.kernel.org@lists.infradead.org From: Marouene Boubakri On RISC-V, OP-TEE runs as a supervisor domain isolated from the Rich Execution Environment by the M-mode firmware. There is no SMC or HVC instruction to reach it: the kernel invokes OP-TEE through the TEE service group of the RISC-V Platform Management Interface (RPMI) v2.0, carried on an SBI Message Proxy (MPXY) channel. Each call is a TEE_CALL service request whose service data carries the register arguments of the OP-TEE SMC ABI, so the ABI itself is unchanged from Arm. Add a binding for such an OP-TEE instance. The compatible string keeps the "linaro" vendor prefix of "linaro,optee-tz" which identifies the OP-TEE reference implementation. The node references the MPXY mailbox channel implementing the TEE service group, and carries the endpoint identifiers assigned by the RPMI TEE framework to the REE and to OP-TEE since the framework does not define any way for an endpoint to learn them other than the optional TEE_PROBE_SYSTEM service, whose CBOR encoded response cannot be parsed in the kernel.
