I wanted to test the virtex440-ml507 qemu machine and found that the dtb
for it was not builded.

Just do:

make virtex440-ml507.dtb

I actually thought you had to do that, so I've never done anything different.

All powerpc DTB are only built when CONFIG_OF_ALL_DTBS is set which depend on
COMPILE_TEST.
But building DTB is not related to a "compile build test".

But it is. We normally only build the dtbs for enabled platforms just
like we only build platform/driver code for enabled platforms. It's
hidden behind COMPILE_TEST so it only gets enabled for
allmodconfig/allyesconfig builds.

So this patch made building of DTB independent of COMPILE_TEST (by
depending only on the PPC arch)
A better selection of which DTB to build could be done in the future
like that do the ARM arch.

No reason you can't start that now for the platform you care about.
You don't have to convert everyone.

Yeah that seems like the best option. I'm happy to take a patch just for
that target.
