tpudrv12.h: FCDEV3B goes back to being itself A while back we had the idea of a FreeCalypso modem family whereby our current fcdev3b target would some day morph into fcmodem, with multiple FC modem family products, potentially either triband or quadband, being firmware-compatible with each other and with our original FCDEV3B. But in light of the discovery of Tango modules that earlier idea is now being withdrawn: instead the already existing Tango hw is being adopted into our FreeCalypso family. Tango cannot be firmware-compatible with triband OM/FCDEV3B targets because the original quadband RFFE on Tango modules is wired in TI's original Leonardo arrangement. Because this Leonardo/Tango way is now becoming the official FreeCalypso way of driving quadband RFFEs thanks to the adoption of Tango into our FC family, our earlier idea of extending FIC's triband RFFE control signals with TSPACT5 no longer makes much sense - we will probably never produce any new hardware with that once-proposed arrangement. Therefore, that triband-or-quadband FCFAM provision is being removed from the code base, and FCDEV3B goes back to being treated the same way as CONFIG_TARGET_GTAMODEM for RFFE control purposes.
