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. endmenu
