I have never seen it as a goal. Let's see: iss doesn't have devices at all,
virt based on it is DT-only, xtfpga with DT loses USB host support, but
it hasn't really been all that useful. xt2000 is the only xtensa platform that
does not support device trees now. I can convert the code, but I don't have
the hardware to test it. I also know that it hasn't been in use in Cadence.
Maybe Chris has it? If not then I guess we can drop it.
