 * Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
 * need to be able to initialize the PCIe wifi device. Normally, this is done
 * during the early stages as a pci quirk.
 * However, this isn't possible for devices which have the init code for the
 * Atheros chip stored on UBI Volume on NAND. Hence, this module can be used to
 * initialize the chip when the user-space is ready to extract the init code.
