[avr-gcc-list] reserve some RAM for bootloader

i'd like to have a bootloader and a normal application in an ATMega128
and have the interrupt vectors in handled in the bootloader.

The bootloader should catch some of the interrupts and forward the
others to the application program.

For this i'd like to reserve some RAM for the bootloader that the application
should not use.

Is it possible to just set the start address of .data to a higher value than
normal for the application?  Would that be just sufficient?

Do i also need to add the offset of 0x00800000?

Best regards,
