This patch could be dropped. Previously, I could not select OP-TEE in imx_v6_v7_defconfig, seems things changed. I'll move this to imx_v6_v7_defconfig. OP-TEE stands for Open Portable Trusted Execution Environment. With Linux running in trustzone nonsecure world, OP-TEE runs in secure world, with TEE/OP-TEE driver enabled, linux could use secure services provided by OP-TEE. With TEE/OP-TEE options selected, we could use the following node to let the driver probed. " firmware { optee { compatible = "linaro,optee-tz"; method = "smc"; }; }; " Thanks, Peng. > >Best regards, >Krzysztof --
