Ah, I see - the IMMR address is duplicated because the nodes you mention are not children of "soc", so they cannot reference that parent address space. I guess re-arranging the hierarchy is not viable, but maybe we can include this orthogonal parent-child relation. For example, could a "reg-parent" phandle solve this duplication?
