+	  Many Tegra devices 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 when

+	  a node compatible with "tl,trusted-foundations" to signal the presence
