Many drivers load the device's firmware image during the initialization flow either from the flash or from the disk. Currently this option is not controlled by the user and the driver decides from where to load the firmware image. 'fw_load_policy' gives the ability to control this option which allows the user to choose between different loading policies supported by the driver. This parameter can be useful while testing and/or debugging the device. For example, testing a firmware bug fix.
