[avrdude-dev] Patch for fuse and lock-bits with avr910

[Jan-Hinnerk Reichert]

Hi all,

I have written a patch that allows to read and write fuse bits with an avr910 
programmer (at least if it supports the "New Universal Command").

Should work with avr910 version 2.2 and newer (don't have access to older 
firmware.

Patch is against latest CVS version of "avr910.c"

This is how it works:
1) It implements "avr910_cmd()": sending arbitrary SPI-commands
2) avr910_read_byte() and avr910_write_byte() call avr_read_byte_default(), 
resp. avr_write_byte_default(), if memtype is neither flash nor eeprom.

This is the first time I have ever used diff, so please tell me if I did 
something wrong ;-)))

BTW: IMHO "stk500_cmd()" returns wrong values in res[0]..res[2]
