+ bool "Trusted Foundations secure monitor support"
+ depends on ARM
+ help
+ Some devices (including most early Tegra-based consumer devices on
+ the market) are booted with the Trusted Foundations secure monitor
+ active, requiring some core operations to be performed by the secure
+ monitor instead of the kernel.
+
+ This option allows the kernel to invoke the secure monitor whenever
+ required on devices using Trusted Foundations. See the functions and
+ comments in linux/firmware/trusted_foundations.h or the device tree
+ bindings for "tlm,trusted-foundations" for details on how to use it.
