Patching_AVR_GCC

If you want to add support for new devices, in most cases you have to patch several files.

They are listed here.

gcc

/usr/src/avr-toolchain-src/gcc-3.4.4/gcc/config/avr/avr.c (line 162 ff)
                                                   /avr.h (CPP_SPEC, LINK_SPEC, CRT_BINUTILS_SPECS)
                                                   /t-avr (MULTILIB_MATCHES)

binutils

/usr/src/avr-toolchain-src/binutils-2.16.1/gas/config/tc-avr.c

avr-libc

/usr/src/avr-toolchain-src/avr-libc-1.2.5/configure.in
                                         /include/avr/io.h
                                         /include/avr/eeprom.h
                                         /include/avr/xxx.h

The file xxx.h is the header file, that is specific for the new device, e.g. iom1280.h Normally the file eeprom.h shouldn't need no patching any more.
