It is currently out of tree, but here you can see the relevant code:

mtd_offset=mtd_get_device_offset(mtd);
put_mtd_device(mtd);
if (do_jmp){
    ret=qt5023_hwicap_reset(head,mtd_offset);
    if (ret){
        dev_err(&head->pci_dev->dev,"error: Failed to jump to new bitfile\n");
        vfree(buffer);
        release_firmware(firmware);
        return -EIO;
    }
    qt5023_spi_restart(head);
}

Thanks
