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

Just do:
make virtex440-ml507.dtb

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.

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

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

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