no-map; } m4 { ... memory-region = <&rsc_table>; } Current require node name have to be rsc-table, but no any binding doc to restrict it. Since memory node names are not constrained by the binding, incorrect names can silently pass DT validation, as seen in examples using "vdevbuffer" instead of "vdev0buffer" ([1] and [2]). Add optional memory-region-names property to define such ABI. To keep back compactiblity, use "optional".
