Provide symbole for RAM memory area.

Browse Source 
The RAM memory area symbols are referred by the startup code. The 64k and 128k variant say "for assembler" so it may be not necessary to do that there. However given the "limited" state of documentation for the target I don't assign too much value to those statements.

Additionally it's unclear to me why two variants provide symbols for the ROM memory.
