Commit:c2dd23840ce5875deca09673fcb8abb8dc3a8e7a
Message:Moved fw/ and tools/ into atrf/ as well.

- fw/: moved to atrf/fw/
- tools/: moved to atrf/tools/
- atrf/fw/atspi/Makefile, atrf/fw/boot/Makefile: updated relative path to
f32xbase
- atrf/tools/Makefile: updated relative path to Makefile.recurse
- atrf/tools/atspi-id/Makefile, atrf/tools/atspi-reset/Makefile,
atrf/tools/atspi-rssi/Makefile, atrf/tools/lib/Makefile: updated relative
path to f32xbase
- atrf/fw/include/at86rf230.h: corrected path in title
- atrf/tools/include/atspi.h: added title and copyright header
