Add a new ioctl command into driver's ioctl handler, then add a user
space program to parse the raw ucode, and send the parsed results to
driver through the newly added ioctl command.  Driver can then load
the results (e.g. text and data segments) into device.  Take a look at
iwi(4) and iwicontrol(8) for example.
