From 967c9cca2cc50569efc65945325c173cecba83bd Mon Sep 17 00:00:00 2001 From: Jens Wiklander Date: Wed, 11 Mar 2015 14:39:39 +0100 Subject: tee: generic TEE subsystem MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 and Emmanuel MICHEL * "Generic TrustZone Driver" by Javier González Acked-by: Andreas Dannenberg Tested-by: Jerome Forissier (HiKey) Tested-by: Volodymyr Babchuk (RCAR H3) Tested-by: Scott Branden Reviewed-by: Javier González Signed-off-by: Jens Wiklander --- drivers/Kconfig | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/Kconfig') diff --git a/drivers/Kconfig b/drivers/Kconfig index 117ca14ccf85..ba2901e76769 100644 --- a/drivers/Kconfig +++ b/drivers/Kconfig @@ -204,4 +204,6 @@ source "drivers/fpga/Kconfig" source "drivers/fsi/Kconfig" +source "drivers/tee/Kconfig" + endmenu -- cgit v1.2.3
