Rene Liebscher d72a56ef01 patch #7688: Implement parent programmers feature
* avrdude.conf.in: updated documentation comment and some programmers 
    have now parents
  * config_gram.y: initpgm will now called at first use of programmer 
    in main. parser sets only the function pointer in the pgm structure.
    Pin and pin lists definitions can now be empty to remove the parents
    setting.
  * doc/avrdude.texi: updated documentation
  * main.c: added call to pgm->initpgm after locate_programmer
  * pgm.[hc]: added field initpgm in structure, added function pgm_dup

Rene Liebscher 0a84dcee24 bug #34302: Feature request : device configuration with parent classes
* config_gram.y: if memory section is overwritten old entry is removed
        
(not in original patch)
* config_gram.y: if programmer or part is defined twice, a warning is
  output and the first instance is removed
        
General cleanup and free functions, so valgrind does not report any lost
blocks at program end.
* avrpart.[hc]: added avr_free_(opcode|mem|part) functions
* pgm.[hc]: added pgm_free function
* update.[hc]: added free_update functions
* config.[hc]: added cleanup_config function, use yylex_destroy to reset
  the lexer after usage. (So it can be reused.)
* main.c: add cleanup_main function which is called by atexit() (This 
  frees all lists so that at program exit only really lost memory is 
  reported by valgrind.)
* usbasp.c: added libusb_free_device_list() and libusb_exit() calls to
  avoid lost memory
* buspirate.c: moved memory allocation from initpgm to setup and added 
  free in teardown
* configure.ac: add definition of HAVE_YYLEX_DESTROY if $LEX is flex.
* Makefile.am: added . in front of SUBDIRS to build avrdude before trying
  to use it for creating the part list for the docs.

Joerg Wunsch d742827da1 Mega-commit to bring in memory tagging.
Each memory image byte is now tagged as it's being read from a file.
Only bytes read from a file will be written or verified (modulo page

Joerg Wunsch 37fbb66f07 Clean-up the Xmega erase functions.
* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
the various XMEGA_ERASE_* definitions (from updated
appnote AVR067)
* jtagmkII.c (jtagmkII_chip_erase): Correctly implement
Xmega chip erase based on CMND_XMEGA_ERASE.
* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
to be just a chip erase.
* jtagmkII.c (jtagmkII_program_disable): Don't try reading
"hfuse" for Xmega parts; they don't have it.
* main.c (main): Re-enable auto-erase.  It's been done
before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
anyway.  Xmega boot and application flash areas should be
handled separately in the future, so auto_erase can only
affect the area just being programmed.

allow to continue with -F if it failed yet do not attempt to
perform anything on the device itself.  That way, -tF could be

device connected, just in order to allow changing parameters on

Joerg Wunsch 5d0bfcaf4c First implementation of ATxmega support. By now, only the
PDI mode of the STK600 is supported.  Single-byte EEPROM
(and flash) updates do not work yet.
* avr.c: "boot" memory is a candidate memory region for paged
operations, besides "flash" and "eeprom".
* avrdude.conf.in: add ATxmega128A1 and ATxmega128A1revD
* avrpart.h: add the AVRPART_HAS_PDI flag (used to distinguish
ATxmega parts from classic AVRs), the nvm_base part field, and
the offset field for a memory region.
* config_gram.y: add "has_pdi", "nvm_base", and "offset"
* lexer.l: (Ditto.)
* main.c: disable auto_erase for ATxmega parts
* stk500v2.c: implement the XPROG functionality, and divert to
this for ATxmega parts
* avrdude.1: Document the changes.

called upon exit.  This allows the programmer implementation to
dynamically allocate private programmer data.

*Problem in verbose output of previous commit. I hoped to
   have all the verbose changes in a single commit, but that
   won't happen...
  *Main thing is fixed safemode to turn itself off when you can't
   read the fuses anyway. I don't know what I was thinking when
   I made it fail out of programmers that don't support fuse reading.

Joerg Wunsch 2682d0a227 More backend/library abstraction and generalization: turn the
list_parts() and list_programmers() functions into general list
iteration functions that call a caller-supplied callback for each
element.  Implement list_parts() and list_programmers() as private
functions in main.c based on that approach.


git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@724 81a1dc3b-b13d-400b-aceb-764788c761c2

Joerg Wunsch 5bf9e2d9f2 Major code cleanup.
- Make all internal functions "static".
- Make sure each module's header and implementation file match.
- Remove all library-like functionality from main.c, so only
  the actual frontend remains in main.c.
- Add C++ brackets to all header files.

That effectively leaves the various module C files as something like
an "avrdude library", with main.c being the currently only frontend
program for that library.  In theory, it should be possible to write
different frontends using the same library backend functions though.

Joerg Wunsch 7dba7155a2 Make avrdude Solaris-compatible.
* Makefile.am: distclean avrdude.conf.
* avrdude.conf.in: make the parallel-port programmers optional.
* bitbang.c: move the bitbang features out into PROGRAMMER.
* configure.ac: introduce --enable-parport, add Solaris.
* lexer.l: replace str by strng to work around problems in some
versions of flex.
* main.c: move getexitspecs into the respective programmer's
domain; replace rindex by the C-standard strrchr.
* par.c: make parallel port optional.
* par.h: everything but par_initpgm() is private now.
* pgm.h: add setping/getping/highpulsepin/getexitspecs.
* serbb_posix.c: generalize bitbang interface; replace
cfmakeraw() by explicit code.
* serbb_win32.c: generalize bitbang interface.

Joerg Wunsch e8e2067639 * main.c(do_op): use mem->desc in place of upd->memtype to
give the full name of the respective memory area, instead of
the (possibly abbreviated) name the user typed in the -U option.

Joerg Wunsch 37fb76687a Add the forgotten -B option (JTAG bit clock) to the getopt() option
string.  Actually evaluate that number as microseconds then, as the
documentation used to state already.

While being there, re-sort the -s option into alphabetical order.

Brian S. Dean c941cf8ab4 This is Colin O'Flynn's mega patch for updating safemode support:
* add support for parts with just 'fuse' memory

    * if any fuse memories are altered, reflect those changes in the
      post-programming safemode check so that safemode no longer
      complains about fuses which were intentionally altered; this
      eliminates the need to completely disable safemode using -u in
      order to program fuses.

    * provide -s option which will not ask to restore fuses, it will
      just do it

Brian S. Dean 43439bcc7a Don't call exit() directly here - set the exit value and jump to the
main_exit: label to ensure the programmer is released correctly.
