I am not sure what you are asking. To enable the use of the external RAM you
must set up the correct control registers. If it is alreasy setup, and you want to
be able to place some variables in the external RAM, you have to change your
linker script. You can add a section, and in the linker script you set up the size
and address of the section. When defining a variable, you can use the section
attribute to have it allocated in the specific section. You can also force all variables
in a specific module to be placed in a specific section.

Hope this helps
