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?
Cheers
