Alternatively, I could add motherboard node property, something like:

/ {
        motherboard {
		arm,v2m-memory-map = "legacy";

and

/ {
        motherboard {
		arm,v2m-memory-map = "rs1";

That way the "legacies" and "rses" will disappear from the main
compatible value:

	compatible = "arm,vexpress-<model>", "arm-vexpress";

and everyone will be happy :-) There will be a bit more hassle with
getting this property in v2m.c, but not too much. Does it make any
sense?

Cheers!
