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. > > So how do I get the same effect?

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.
