sama5d2 support from DRAM will be modified to use device tree instead of hardcoded addresses. In order to prepare that, add the memory node to sama5d2.dtsi file since the boards supported by U-Boot with sama5d2 all contains 512Mb of DDR.

memory {reg = <0x20000000 0x20000000>;};Hi,
Memory is external to the SoC. You have to move this node to the board specific DTS.
Ok, I'll move this to sama5d2_xplained only since this series has been made and tested on sama5d2_xplained/sama5d27_som1_ek.

Even if all current boards have 512 MB of DRAM , this does not belong here.
And by the way this is not true, since this SoC can work in a SiP with only 256 or 128 MB of DRAM for example and this is true for certain boards ( wlsom1_ek comes to my mind now).
