[avr-gcc-list] External memory mapping problem

Hi All!

I have the following memory configuration for an ATMega103:

intenal RAM: $0060- $0FFF (4K)
free space for memory mapped devices: $1000- $7FFF
32K external RAM: $8000- $FFFF (32K)

- Does anybody knows how the linker script file should be modified (the 'data' 
section I suppose) in order to tell the linker about the 36K of available SRAM?

- Is the linker capable to manage this type of configuration? I mean that can I 
tell the linker to use for variables, etc. the SRAM from $0060-$0FFF and 
$8000-$FFFF  ?

I have seen somewhere on the net something like this in a source with a memory 
mapped ethernet card, unfortunatly I can't find the code anymore.

Any help would be appreciated
