If we choose not to intermingle .dts files from all the vendors in a
single directory, why do anything at all? Currently the .dts files for
a vendor are nicely segregated with the rest of the vendors code under a
single directory.
Personally I think things are fine as they are. Any common code
remaining in the Makefiles could be moved to the scripts directory for a
smaller change.
