  while the current DTSpec says nothing about the chosen node
possibly having a unit-address, if i search the current linux
kernel code base, there are a few examples of just that:

$ git grep chosen@
arch/mips/generic/yamon-dt.c:           chosen_off = fdt_path_offset(fdt, "/chosen@0");
arch/mips/generic/yamon-dt.c:           chosen_off = fdt_path_offset(fdt, "/chosen@0");

Nothing MIPS based should need this I think.

  i just submitted a patch to the MIPS list, and they're applying it
to mips-next for 4.19, so i just need to browbeat the PPC folks into
dropping it, and all references to "/chosen@0" can be tossed entirely.

  i love deleting stuff.
