I recall reading that the ARM organization for DTS files was a bit
unfortunate and should have been something like:

arch/arm/boot/dts/<vendor>/

Is this something we should do for the MIPS and update the other
architectures to follow that scheme?

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.
