	  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

	  tlm,trusted-foundations device tree binding documentation for details

	  on how to use it.



	  Say n if you don't know what this is about.
