I
did inspect the output dtb (made by merging two overlays) using
fdtdump and it looked okay.

Ok.. but if you're using these bizarre messed up "dtbs" that this test
code seems to be, I don't really trust that tells you much.

I only looked if the changes from the second overlay were present in
the merge and they were. And so I assumed that it must have worked.

What about checking the base dtb for /plugin/; in fdtoverlay and fail
the whole thing in case it is present ? I think it is possible for
people to get confused otherwise, like I did.
