Instead of doing this, I think it will be easier if you start from the
current mx53loco nad make the customization for your board. Freescale's
U-Boot (2009.08) and mainline diverged, as well as some internal API.

You do not need to care about that. Cache is activated per default with
mx5/mx6, if you do not explicitely deactivate it in your config file.
You do not need to bother about MMU setup in your board files.
