Werner Almesberger a9321cea7c libatrf: new function atrf_identify to identify the chip
- tools/lib/atrf.h, tools/lib/atrf.c (atrf_identify): added chip
  identification function to library
- tools/atrf-id/atrf-id.c (show_info): print information returned by
  atrf_identify
- tools/atrf-id/atrf-id.c (show_info): decode JEDEC manufacturer ID
