Hi,

great work.
There is also rules/host-dtc.make which maybe can be simplified.

Yes. I expect qemu select DTC once someone (hint, hint) updates qemu :)
Here's updated version, please give it a try.

Subject: [PATCH] dtc: new package

From: Ladislav Michl <ladis@linux-mips.org>

Please note this package is not as symmetrical as the typical
host-* and normal variants. Here the latest version is usually needed.

This work is prepping for qemu 8.2.0+, as it requires libfdt as a separate
library. It has stopped providing one internally.

Right. It may be time to remove the special version handling in host-dtc
but that's a different discussion.

Is it fine to do like this or should it be split into MAKE_ENV
