Hi Yannick, I think this needs to be two separate patches. The FPU change is logically one. The change to the MCF5441x config is another - and it really needs to be the last one in the series (so that all the actuall code support is in place first).

m5441x coldfire chips contains a MMU and no FPU. This patch allow building this chip with MMU activated.
