FreeRTOS on Freescale MAC7121 ARM7 series?

Has anybody ported or part ported the FreeRTOS to the Freescale MAC7xxx ARM7 series of processors? We are using the IAR development environment. I need to quickly test performance on the MAC7121 processor to determine if going forward is a worthwhile investment for a current project that runs on PIC32 and MAC7121 hardware platforms. PIC32 was easy to try but looking to save reinventing the wheel for the MAC processor if anybody can assist?
