-m128k
This option instructs the linker to generate code for parts with between 8K and 128 kilobytes of code memory. For devices that have 8K of code memory or less, you should use the -m8k switch so that RJMP instructions are always used, and for devices with more than 128K of memory you should use the -m8m switch so that the wider program counter of these devices is correctly supported.
