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.
