This is a relatively significant edit that brings the Arduino copy of optiboot up-to-date with the optiboot source repository as of Jun-2011 (the last changes made in the optiboot repository were in Oct-2010) This adds support for several plaforms, fixes the "30k bug", and refactors the source to have separate stk500.h, boot.h, and pin_defs.h These are the arduino opticode issues fixed: http://code.google.com/p/arduino/issues/detail?id=380 optiboot has problems upload sketches bigger than 30 KB http://code.google.com/p/arduino/issues/detail?id=556 update optiboot to the point of the latest optiboot project sources. These are issues that had been solved in the optiboot source aready: http://code.google.com/p/arduino/issues/detail?id=364 optiboot leaves timer1 configured when starting app, breaks PWM on pin 9 and 10. (fixed with a workaround in arduino core.) aka http://code.google.com/p/optiboot/source/detail?r=c778fbe72df6ac13ef730c25283358c3c970f73e Support for ATmega8 and mega88. Fix fuse settings for mega168 _ISP targets Additional new platforms (mega, sanguino) http://code.google.com/p/optiboot/issues/detail?id=26 Set R1 to 0 (already in arduino code) http://code.google.com/p/optiboot/issues/detail?id=36&can=1 Fails to build correctly for mega88 After this commit, the only differences between the Arduino optiboot.c and the optiboot repository optiboot.c are cosmetic. (cherry picked from commit e2812ef91cc1489527827dcd14c843f3b3244f36)

Fix to optiboot infinite loop problem. Explicitly setting R1 to 0 so that the watchdog timer is properly initializing, preventing it from timing out and resetting the processor. http://code.google.com/p/optiboot/issues/detail?id=26 http://code.google.com/p/arduino/issues/detail?id=446

Add a version number to the optiboot source and binary. http://code.google.com/p/arduino/issues/detail?id=554 end of flash memory where they can be read (at least in theory) by device programmers, hex-file examination, or application programs. This is done by putting the version number in a separate section (".version"), and using linker/objcopy magic to locate that section as appropriate for the target chip. (See http://lists.gnu.org/archive/html/avr-gcc-list/2011-02/msg00016.html for some discussion on the details.) Start the version at 4.1 (the last "packaged" version of optiboot was called version 3, so the "top of source" would be 4.0, and adding the version number makes 4.1) Refactor LDSECTION in the Makefile to LDSECTIONS so that multiple section start addresses can be defined. Change the _isp makefile definitions to make the bootloader section readable (but not writable) by the application section. (This would need to be done elsewhere as well to handle all bootloader programming techniques. Notably Arduino's boards.txt Note that this change does not change the "code" portion of optiboot at all. The only diffs in the .hex files are the added version word at the end of flash memory.
