When enabled, this option instructs the Zephyr build process to

|
additionally generate a TF-M image for the Secure Execution
|
|
environment, along with the Zephyr image. The Zephyr image
|
|
itself is to be executed in the Non-Secure Processing Environment.
|
|
The required dependency on TRUSTED_EXECUTION_NONSECURE
|

ensures that the Zephyr image is built as a Non-Secure image. Both

TF-M and Zephyr images, as well as the veneer object file that links

them, are generated during the normal Zephyr build process.

Notes:

Building with the "_ns" BOARD variant (e.g. "mps2_an521_ns")
|

ensures that CONFIG_TRUSTED_EXECUTION_NONSECURE is enabled.
|
|
|

By default we allow Zephyr preemptible threads be preempted

while performing a secure function call.
