Well, it just includes the arm64 version as-is, so we don't have
duplication. I'm open to suggestions to how handle this better.
Symbolic link?
Reference to ../../../arm64/boot/dts/broadcom/bcm2837-rpi-3-b.dts
directly in the Makefile?
I've seen arch/arm/boot/dts/Makefile uses globs on *.dts, so I suspect
the later wouldn't be that straight forward.
cheers,
Gerd
