+ Some devices (including most 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
+ arch/arm/include/asm/trusted_foundations.h or the
+ tl,trusted-foundations device tree binding documentation for details
+ on how to use it.
+
+ Say n if you don't know what this is about.
