Assuming that you want the section/symbols to reside at the defined
address (my_address) after the first linking step you can do the
following in the linker script

for symbol:
                foo = ABSOLUTE(my_address);

for section:
              SECTIONS{
                             my_sec my_address:   AT(my_address) { }
               }

If you want to have the section/symbols to reside at the defined
address in final image too then follow the above steps in each linker
script you use in every linking step.
