For any given design with the cw1200, you're likely to need an SDD file 
specific to that design.  That's because the SDD file includes GPIO 
mappings to control the RF front end, plus things like bluetooth 
coexistence parameters, reference clocking information, and some 
calibration data and output power limitations.  Oh, and a macaddr too, 
but that's generally overridden by the device driver anyway (eg via 
platform data)

Most wifi chipsets requiring this sort of information have an embedded 
or attached eeprom, but the cw1200 doesn't (presumably for cost 
reasons), as it was intended to be used in cellphones that already 
maintained per-device platform data.

So in short, there's no way to include a generic SDD file that will work 
on all cw1200-based modules, and there's no way to detect which 
particular cw1200-based device has been plugged in without the 
information in the SDD file.  It's a right kerfuffle.
