*Trusted Execution: Secure firmware image*

Type: ``bool``

Help
====

.. code-block:: none

    Select this option to enable building a Secure firmware
    image for a platform that supports Trusted Execution. A
    Secure firmware image will execute in Secure state. It may
    allow the CPU to execute in Non-Secure (Normal) state.
    Therefore, a Secure firmware image shall be able to
    configure security attributions of CPU resources (memory
    areas, peripherals, interrupts, etc.) as well as to handle
    faults, related to security violations. It may optionally
    allow certain functions to be called from the Non-Secure
    (Normal) domain.

Direct dependencies
===================

*(Includes any dependencies from ifs and menus.)*

Defaults

No defaults. Implicitly defaults to ``n``.
