Excellent!

Basically we have been talking about fetching calibration data via the
request_firmware() interface. In user space there would be a udev script
which would dynamically retrieve the calibration data specific to the
platform it is running on. In N800/N810 case that would mean to run
stlc45xx-cal and provide the calibration data to the driver. 

This way we can have platform specific implementations and use already
existing user space interface. The idea was discussed in this mailing
list few months ago. The implementation details are currently unknown to
me. I was planning to talk about this at the Wireless Summit, but of
course I forgot :/

stlc45xx-cal will most probably need some changes, maybe dumping the
calibration data to stdout so that udev script can forward it to the
driver? I can do the necessary changes to stlc45xx-cal, but it's better
to have a some sort of working prototype before I'll start changing
stlc45xx-cal.
