That would be rather odd. These nodes are in the top level SoC dtsi
file. When they are not used, they have status = "disabled" and are in
the dtb blob with this state.

The only reason i can think of them not being present at all is if
somebody adds an optimizer to dtc which removed disabled nodes. What
does the device tree spec say about that? Are we relying on undefined
dtc behavior?

There is no requirement to use the include files. If someone decides
to ship a default dtb file in their boot loader, it wouldn't be
a bug to leave the nodes out entirely.
