well, I don't care about that too cause we usually don't have a
dataflash in our devices.

I think for the eval kits it would be nice to have a board support
package which can be loaded from different media. Unfortunately I used
to work with bare UBoot, vanilla kernel a.s.o. Therefore I have not such
deep insight into the atmel provided bsp's. In short words: I tend to
say we should increase the space for kernel partition but I fear to
break some special bsp's.
As I can see the kernel do not provide a special mapping here. If you
are not aware of some other source (e.g. linux4sam), let us increase the
space for kernel a bit.

Best regards
