+	  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.
