Subject: tee: add ARM_SMCCC dependency
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e84188852a7239d7a144af12f7e5dac8fa88600b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tee: add ARM_SMCCC dependency

For the moment, the tee subsystem only makes sense in combination with
the op-tee driver that depends on ARM_SMCCC, so let's hide the subsystem
from users that can't select that.
