zynq-7000.dtsi include skeleton.dtsi which contains memory node with base address and size zero. If you add memory@0 node to the platform DTS in final DTB there are two memory nodes and U-Boot works with the first one (with zeros) which end up in failing in dram_init because size is zero. Platform memory node should rewrite default memory node setup from skeleton.dtsi that's why platfroms needs to also use memory as node name instead of memory@0.
