Hi Tim,
If the memory you are using is not listed as part of the supported flash devices you can follow the Application Note AN3390 that explains how to add a new flash device, the document can be found on this path:
C:\Program Files\Freescale\CodeWarrior for ColdFire V7.2\Help\PDF\AddFlashDevs.pdf
Let me know if it helps!
Best Regards,
