I have already done so (in the latest series I sent yesterday).

Okay, but fdtoverlay tool can't apply overlay_base.dtb to
testcases.dtb as none of its node have the __overlay__ property and so
I have entirely skipped overlay_base.dtb and overlay.dtb now.
Yes this reduces the test coverage a bit as you said, but I don't see
a way to make it work right now. And I am not even sure if it is a
fdtoverlay bug, it expects the __overlay__ thing to be there for each
node, otherwise it can't figure out where this node should be applied.
