Why don't you want to use the remote_upgrade megafunction? What you need is a minimal interface to the remote upgrade megafunction, needing just a single register of your application and the rem_update block existing in the FPGA hardware. 

rem_update_inst : rem_update PORT MAP (
  clock	 => CLK,
  reset	 => RESET,
  reconfig	 => reconfig_req
);
