Subject: [PATCH v5 1/5] tee: add sec_world_id to struct tee_shm
Date: Tue, 31 Aug 2021 09:24:08 +0200 [thread overview]
Message-ID: <20210831072412.887565-2-jens.wiklander@linaro.org> (raw)
In-Reply-To: <20210831072412.887565-1-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.
