This patch enables configs for Trusted Execution Environment(TEE) and Open Portable Trusted Execution Environment(OP-TEE). With Linux running in Trustzone non-secure world, OP-TEE OS runs in secure world, linux could use secure services provided by OP-TEE. With TEE/OP-TEE options selected, use the bindings in Documentation/devicetree/bindings/arm/firmware/linaro,optee-tz.txt to let the driver probe work. On i.MX6/7, now the bootflow is U-Boot->OP-TEE->Linux, OP-TEE will automatically create that node. Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
