No doubt it's been bitrotting (or I may have missed some).

I assume I built everything after moving, but maybe not...

That's all just "details". First, we need agreement on a) moving
things to subdirs and b) doing it 1-by-1 or all at once. So far we've
been stuck on a) for being 'too much churn'.

One nice thing with subdirs is 'make CHECK_DTBS=y
arch/arm/boot/dts/foo/' can build everything for a platform family
without having to mess with the kconfig. Maybe most folks don't care,
but I do. My CI job running schema checks looks like this to deal with
grouping the arm dts files (this list is probably out of date too, but
less so):

        if [ "$ARCH" = "arm" ]; then
            VENDOR_LIST="alphascale alpine artpec aspeed axm bcm cx9
