	  This option indicates that we are building a Zephyr image that

	  is intended to execute in Non-Secure state. Execution of this

	  image is triggered by Secure firmware that executes in Secure

	  state. The option is only applicable to ARMv8-M MCUs that

	  implement the Security Extension.



	  This option enables Zephyr to include code that executes in

	  Non-Secure state only, as well as to exclude code that is

	  designed to execute only in Secure state.



	  Code executing in Non-Secure state has no access to Secure

	  resources of the Cortex-M MCU, and, therefore, it shall avoid

	  accessing them.
