2012-04-19  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	bug #29019: pagel/bs2 warning when uploading using stk500 to xmega
	* stk500.c (stk500_initialize): Insert dummy values for PAGEL and
	BS2 if they are not present in the config file, in order to be able
	to proceed with the stk500_set_extended_parms() anyway.

2012-04-19  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* stk500v2_private.h (struct pdata): add boot_start
	* stk500v2.c: For the "flash" pseudo-memory of Xmega devices,
	distinguish addresses between "application" and "boot" area.

2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* fileio.c (elf2b): When checking the bounds of the current
	program header segment, subtract `low' from ph[n].p_paddr in order
	to correct the magic section offsets for the AVR's non-flash
	memory regions.

2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* fileio.c (elf_get_scn): Rather than trying to just match whether
	any given section maps straight to a program header segment, use a
	more sophisticated decision that matches any section as long as it
	fits into the segment.  This is needed for situations where the
	program header segment spans a larger area than the section data
	provided.  (This can e.g. happen in an ELF file that contains no
	data at address 0, like a bootloader only.)

2012-04-13  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	bug #28744: Can't load bootloader to xmega128a1 (part 2, fix for
	firmware >= V7.x)
	* jtagmkII.c: Add firmware-version dependent handling of Xmega parameters.
	V7.x firmware expects the NVM offsets being specified through the Xmega
	parameters command, but left out as part of the memory address itself.
	* jtagmkII_private.h: Add CMND_SET_XMEGA_PARAMS, and struct xmega_device_desc.
	* config_gram.y: Add mcu_base keyword.
	* avrpart.h: (Dito.)
	* lexer.l: (Dito.)
	* avrdude.conf.in (.xmega): add mcu_base, and data memory segment.

2012-03-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	bug #28744: Can't load bootloader to xmega128a1 (part 1, fix for
	firmware < V7.x)
	* jtagmkII.c: When going to write to the boot section of flash,
	use MTYPE_BOOT_FLASH rather than MTYPE_FLASH
	* jtagmkII_private.h: add MTYPE_BOOT_FLASH constant

2012-03-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* jtagmkII_private.h: Sort commands, response codes and events
	into numerical order.

2012-03-29  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	bug #30451: Accessing some Xmega memory sections gives not
	supported error
	* stk500v2.c: Handle all Xmega memory sections (except
	"prodsig" which is not documented in AVR079)
	* fileio.c: Treat the "boot", "application", and "apptable"
	regions (which are actually subregions of "flash") all as
	being flash, i.e. suppress trailing 0xFF bytes when reading
	them
	* avr.c: (Dito.)

2012-03-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* jtagmkII.c (jtagmkII_close): The GO command before signing off
	turned out to be not required for normal megaAVR devices, and to
	cause the exact opposite (i.e. the target stopping) on Xmega
	devices being programmed to JTAG.  However, programming Xmega
	devcies through PDI *does* need the GO command.

2012-03-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* configure.ac: Print a configuration summary at the end of the
	configure run

2012-02-11  Rene Liebscher <R.Liebscher@gmx.de>

	* Makefile.am (avrdude_LDADD): Add @LIBELF@

	* lexer.l: Replace the old, now-defunct #define YY_NO_UNPUT by

2012-01-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	Add a connection_type attribute to each programmer, rather than
	trying to hard-code the default port name in main.c.

	setting.
	* doc/avrdude.texi: updated documentation
	* main.c: added call to pgm->initpgm after locate_programmer

2012-01-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	* configure.ac: Check for presence of lusb_usb.h as an alternative

	* ser_avrdoper.c: (Dito.)

	* usbtiny.c: (Dito.)

2012-01-19  Rene Liebscher <R.Liebscher@gmx.de>

	* avr.c: Unsigned variable was used for return code of paged_write/load
	functions. So a negative return code led never to a fallback to byte
	functions.

2012-01-17  Rene Liebscher <R.Liebscher@gmx.de>

	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.

2012-01-17  Rene Liebscher <R.Liebscher@gmx.de>

	* usbasp.c: USB vid/pid/vendor/product from config file are used, for
	id "usbasp" nibobee and old usbasp are tried as they were currently
	implemented within usbasp
	* avrdude.conf.in: added usb params to "usbasp", added new entry "nibobee"
	with params which were hardcoded in usbasp.c, and added an entry
	"usbasb-clone" which only checks vid/pid.

2012-01-10  Rene Liebscher <R.Liebscher@gmx.de>

	bug #35261 avrftdi uses wrong interface in avrftdi_paged_(write|load)

	Arduino Uno properly
	* arduino.c (arduino_open): Bump the timeout between pulling
	the DTR and RTS lines low and high.

2012-01-08  Rene Liebscher <R.Liebscher@gmx.de>

	* avr910.c:625 (error) Possible null pointer dereference: cmd - otherwise it is redundant to check if cmd is null at line 624

	pwm2b = pwm2 + different signature)
	
	* ChangeLog-2011: New file, rotate ChangeLog for new year.
