I'd prefer to stop the proliferation of identical Kconfigs which are
only used to select which DTB files to compile.

Instead, can you drop this new Kconfig as well as MACH_MESON8, and just
make all the meson8* DTBs build based on MACH_MESON8?

I think it better to have fewer Kconfigs. The only cost is building a
couple extra DTBs.

Thanks,

Kevin
