This:

/dts-v1/;

is missing: I cannot compile the .dts

This is wrong: it can compile better with that:

                       macb0: ethernet at fffc4000 {

if you board is based on an at91sam9260, it is the proper address of the
EMAC.

Please use

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- aks-cdu.dtb
or
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- dtbs

So that you can check that your device tree file is correct.

Anyway, I have added the corrections and pushed this patch in the AT91
at91-3.6-dt branch.

Thanks, best regards,
