2017-12-15tee: flexible shared memory pool creationJens Wiklander1-55/+2
Makes creation of shm pools more flexible by adding new more primitive functions to allocate a shm pool. This makes it easier to add driver specific shm pool management. Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org> Signed-off-by: Volodymyr Babchuk <vlad.babchuk@gmail.com>
2017-03-09tee: generic TEE subsystemJens Wiklander1-0/+129
Initial patch for generic TEE subsystem. This subsystem provides: * Registration/un-registration of TEE drivers. * Shared memory between normal world and secure world. * Ioctl interface for interaction with user space. * Sysfs implementation_id of TEE driver A TEE (Trusted Execution Environment) driver is a driver that interfaces with a trusted OS running in some secure environment, for example, TrustZone on ARM cpus, or a separate secure co-processor etc. The TEE subsystem can serve a TEE driver for a Global Platform compliant TEE, but it's not limited to only Global Platform TEEs. This patch builds on other similar implementations trying to solve the same problem: * "optee_linuxdriver" by among others Jean-michel DELORME<jean-michel.delorme@st.com> and Emmanuel MICHEL <emmanuel.michel@st.com> * "Generic TrustZone Driver" by Javier González <javier@javigon.com> Acked-by: Andreas Dannenberg <dannenberg@ti.com> Tested-by: Jerome Forissier <jerome.forissier@linaro.org> (HiKey) Tested-by: Volodymyr Babchuk <vlad.babchuk@gmail.com> (RCAR H3) Tested-by: Scott Branden <scott.branden@broadcom.com> Reviewed-by: Javier González <javier@javigon.com> Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org>
