Re: [Tee-dev] [PATCH v5 03/10] xen/arm: optee: add OP-TEE mediator skeleton

Add very basic OP-TEE mediator. It can probe for OP-TEE presence, tell it about domain creation/destruction and then return an error to all calls to the guest.

This code issues two non-preemptible calls to OP-TEE: to create and to destroy client context. They can't block in OP-TEE, as they are considered "fast calls" in terms of ARM SMCCC.
