Normally the linker script deals only with memory that is
easy to load into.  If EEPROM requires special programming
to write (which I think it should), then you will have to go through
some special procedure.  You might be able to arrange this but
whatever loads your program will have to recognize the address
range of EEPROM (vs RAM) and do the right thing).
