Modified: trunk/flash.h trunk/flashrom.c Log: Factor out CLI code by moving generic stuff out of main(). Add a generic programmer list output function to be used by alternative frontends. The interface between main() and doit is a hack and should get a clean design, but for now it serves the purpose of shortening main() by 120 lines. The rest of main() needs to be refactored a bit more before moving main() away.
