Porting FreeRTOS on MC9s12xdp512

We are porting the RTOS code on MC9S12XDP512 controller.However we could not find the IO_Map.h file for this controller.Can we get the file?? If not,can someone tell us how to make one?We have IO_Map.h for MC9S12XEP series. The RTOS code uses some memory protection unit in HCS12XE code which we have downloaded.However this unit is not available in MC9S12XDP512.Will that cause some problem? If yes, what care should be taken to prevent it.
