Changes in the current code since fc-host-tools-r7:

* New c1xx-calextr utility can extract the factory RF calibration values for
  Mot C1xx phones from a dump of their flash; see doc/Compal-calibration.

* Support for RF tables in FreeCalypso ASCII format (see doc/RF_tables) is
  more complete: there is an ASCII format for the full 512 byte Tx ramps table,
  any ASCII RF table can be converted to native binary with fc-cal2bin, most
  ASCII RF tables can be uploaded directly into FFS with fc-fsio's new
  upload-rf-table command.

* fc-cal2text change: Tx ramps tables are now emitted in the new ASCII format
  with one file for the whole table, not split into 16 single ramp template
  files any more.

* fc-fsio pirelli-magnetite-init command now copies the previously missed
  /gsm/rf/afcdac record.

* fc-tmsh can now upload audio FIR coefficient sets from FIR coefficient table
  files with the new auw-fir command.

* The audio mode configurations that have been added in fc-host-tools-r7 have
  been moved to a separate fc-audio-config repository and are no longer a part
  of the core FC host tools package.

Changes from fc-host-tools-r6 to fc-host-tools-r7:

* The way in which loadtools, rvinterf and miscellaneous tools operate on
  serial ports for the purpose of talking to Calypso GSM devices has been
  majorly reworked: the serial port handling code has been factored out into
  libserial, and the new libserial uses Linux-specific direct ioctl calls
  instead of generic termios.  The effect is that you can now use the GSM-
  specific high serial baud rates (up to 812500 bps) with FTDI adapters
  (like the FT2232D adapter commonly used with FCDEV3B) with the standard
  unpatched ftdi_sio kernel driver.  See doc/High-speed-serial for more info.

* Added new utilities tiaud-compile and tiaud-mkvol for generating *.cfg and
  *.vol binary files for the audio mode switching facility of TI's RiViera
  Audio Service, to be uploaded under /aud into FreeCalypso GSM devices.

* A set of audio mode tables is built and installed in
  /opt/freecalypso/aud-fcdev3b for uploading into /aud on FCDEV3B boards.

Changes from fc-host-tools-r5 to fc-host-tools-r6:

* loadtools and rvinterf now set TIOCEXCL on the tty to prevent the common
  error scenario of multiple processes trying to read from the same serial
  port.

* fc-loadtool: added a batch operation mode whereby the tool executes a given
  command script, cleans up (usually powers off) the target and exits.

* fc-loadtool exec command: scripts without slashes in the given name are now
  sought in the current directory.

* fc-fsio format command: if the FFS is already formatted, the tool now prints
  the error returned by the FFS code in the target fw, but does not stop the
  execution of scripts; this change makes production scripts rerun-able.

* exitcodes.h file installed in /opt/freecalypso/include/rvinterf: added
  ERROR_RFFAIL definition for use by fc-rfcal-tools.

Changes from fc-host-tools-r4 to fc-host-tools-r5:

* New install location: everything is now under /opt/freecalypso instead of
  /usr/local/bin and /usr/local/share/freecalypso.

* loadtools: added support for dsample (TI D-Sample) and fcfam (FreeCalypso
  hardware family starting with FCDEV3B) targets.

* loadagent: UART autodetection now works not only with Calypso boot ROM
  version 0300 found in the common Calypso devices, but also with the older
  version 0200 found in the older Calypso silicon on early D-Sample boards.

* loadtools support for C139/140 target: use -h compal -c 1004 command line
  options instead of the previous -h compal -c 1003 to support the newer
  versions of C139/140 boot code which expect "1004" instead of the more
  familiar "1003" in the serially downloaded code image.  The new -c 1004
  option ("1004" signature bytes) should work with all currently known
  Mot/Compal boot code versions, thus -c 1003 is retained only for backward
  compatibility with existing usage.

* fc-fsio: one can now type ls -l and not just the ll shorthand,
  pirelli-get-imei and pirelli-magnetite-init commands added (former
  fc-getpirimei and fc-pirhackinit separate utilities absorbed into fc-fsio),
  help facility added.

* fc-tmsh changes:

  + fc-tmsh now takes the -p option and supports one-shot command invokation
    like fc-fsio and fc-shell;

  + added support for L1/RF test mode commands and other TM3 protocol commands
    (omr, omw, oabbr, oabbw, tm3ver);

  + added ETM_AUDIO commands aul, aus, aur and auw.

* fc-olddump renamed to fc-memdump, can now use either TM3 or ETM memory read
  commands.

* tiffs: added -O option to parse FFS images from the ancient 20020917 firmware
  on the D-Sample.

* New in vitro analysis utilities: fc-cal2text and tiaud-decomp.

* Added tools for working with ringtone melodies: fc-e1decode and fc-e1gen for
  loudspeaker melodies (see doc/Melody_E1) and fc-buzplay (plus target-side
  buzplayer.srec) for devices that use a piezoelectric buzzer.

* rvinterf: added support for the keepalive mechanism, see the description in
  doc/RVTMUX.

* rvinterf & fc-shell: added support for the experimental TCH rerouting feature
  of FreeCalypso Citrine firmware.

* fc-fr2tch, fc-gsm2vm, fc-tch2fr, fc-vm2hex: new utilities for converting
  GSM 06.10 FR codec bits between different formats.

* c139explore & pirexplore: added host shell script wrappers invoking
  fc-compalram and fc-iram with the respective target binaries.

* Internal cleanup and refactoring in various places.

Changes from fc-host-tools-r3 to fc-host-tools-r4:

* Shellcode-based Compal phone break-in utility tfc139 reworked in a new way
  that should work with all Mot C1xx firmwares beyond the original TFC139
  target: see doc/Compal-unlock and doc/TFC139-breakin for the details.

* Documentation and cosmetic code changes to reflect the new understanding of
  TI's TM (Test Mode) predating ETM (Enhanced Test Mode): see doc/RVTMUX for
  a detailed explanation.

* Added support for the old non-enhanced Test Mode memory read command in the
  form of fc-tmsh omr command, fc-fsio omemdump command and fc-olddump utility.

* rvtdump and rvinterf recognize the old all-ASCII GPF trace format emitted by
  the D-Sample firmware from 20020917 and print these traces as ASCII instead
  of hex.

* fc-dspapidump fixed to be independent of host byte order.
