Hi,
Following on the special handling of nodes called memory@0, I went to
have a look at the various platforms that do not actually declare a
device_type = "memory" for their "memory" nodes.
Firstly, we currently have 162(ish, I did a sloppy grep) such .dts{i}
files in the kernel tree.
Secondly, the only reason these platforms could ever have worked is
because they include .dtsi files that define a memory node with a
type explicitly set. Since this node already exists, its contents get
overridden, but the type tag remains. Of course, this only happens
with nodes called explicitly "memory" - but it happens regardless of
what other things they contain.
In the ARM tree, most of these seem to stem from the inclusion of
skeleton.dtsi.
I don't really know what could/should be done about this, but it
does not feel optimal.
