is it really necessary to do it this way? cause i don't like the idea
of using a user space program for directing the driver to load the
firmware. instead the firmware can be loaded and cached during the
device attach routine.

the firmware_image_load_file can be the appropriate candidate for such
functionality provided  that it just returns the raw data from the
/etc/xxx firmware file without allocating the dma resources.
