Change subject: firmware/board: introduce new FCDEV3B (FreeCalypso) target ...................................................................... firmware/board: introduce new FCDEV3B (FreeCalypso) target FCDEV3B (stands for "FreeCalypso development board, triband") is a GSM mobile station development board by FreeCalypso project. The board features the same legendary TI Calypso GSM MS chipset that was used in commercial GSM/GPRS modems such as Openmoko's, and functions as a standalone (or "bare") GSM modem. For more information, please see the project's web side: https://www.freecalypso.org/fcdev3b.html.
