Its not like a 68K hardwired MMU, more like a PPC software managed MMU.

Two things to look at:

1) ColdFire v4e core manual, chapter 10:
   http://www.freescale.com/files/dsp/doc/ref_manual/V4ECFUM.pdf

2) Non-PCS COldFire 547x/548x LInux BSP source, and look in
   linux-2.4.26/arch-m68k/coldfire/mm/cfmmu.c for the function
   cf_tlb_miss.
