Driver will throw an error message when a non-secure type controller is detected. Purpose of this interface is to avoid interacting with any firmware which is not secured/signed by Broadcom. Any tampering on Firmware component will be detected by hardware and it will be communicated to the driver to avoid any further interaction with that component.
