+ * @brief Creates all the tasks for TZ demo.

+ *

+ * The Trust Zone (TZ) demo creates an unprivileged task which calls a secure

+ * side function and passes a pointer to a callback function. The secure side

+ * function does two things:

+ * 1. It calls the provided callback function. The callback function increments

+ * a counter.

+ * 2. It increments a counter and returns the incremented value.

+ * After the secure function call finishes, it verifies that both the counters

+ * are incremented.
