There are quite a few things missing from this one, including a bunch
of errata workarounds which allow the data cache to be turned on with
earlier 860T revs - so it is worth using the mvista kernel.

It is likely that you'll need to tweak fec.c for the hardware on your
board. By the sounds of it, writing to FETH_ENABLE before doing anything
would be a good idea for a start. What type of PHY does the board have?

I'm pretty sure there is support for FADS in there (and maybe ADS too),
but I think it comes under the name CONFIG_MBX rather than
CONFIG_FADS/CONFIG_ADS

CONFIG_MPC860T should be set here, not CONFIG_MPC860

It looks pretty good to me otherwise.
