The boards above are the ones that cannot be built with DM=y. Others may
be failing at runtime. Therefore I suggest targeting the v2020.01
release.  If that date is ok, let's add a warning via /Makefile:

"This board does not use CONFIG_DM=y. All boards without CONFIG_DM=y
will be removed from U-Boot with the v2020.01 release."
