Subject: [PATCH v2 1/5] tee: add sec_world_id to struct tee_shm
Date: Thu, 27 May 2021 10:14:00 +0200	[thread overview]
Message-ID: <20210527081404.1433177-2-jens.wiklander@linaro.org> (raw)
In-Reply-To: <20210527081404.1433177-1-jens.wiklander@linaro.org>

Adds sec_world_id to struct tee_shm which describes a shared memory
object. sec_world_id can be used by a driver to store an id assigned by
secure world.
