| 16 | Some devices (including most Tegra-based consumer devices on the |
| 17 | market) are booted with the Trusted Foundations secure monitor |
| 18 | active, requiring some core operations to be performed by the secure |
| 19 | monitor instead of the kernel. |
| 20 | |
| 21 | This option allows the kernel to invoke the secure monitor whenever |
| 22 | required on devices using Trusted Foundations. See |
| 23 | arch/arm/include/asm/trusted_foundations.h or the |
| 24 | tlm,trusted-foundations device tree binding documentation for details |
| 25 | on how to use it. |
