FFS code sync with Magnetite + gcc version fix This change brings the new flash autodetection for FC and Pirelli targets from Magnetite, and should also fix the gcc version for C1xx and gtamodem targets, which were previously broken because they used TI's original flash autodetect code (which operates at address 0) while the boot ROM is mapped there.
