All of them. I.e. the devicetree is supposed to be compatible with all of
those, while the bootloader determines the actual board revision and sets the
choosen compatible - at least that was the way with the previous series of
devices based around the rk3288 (veyron) and I think it will be the same way
still.
I.e. as you can see below, Kevin starts being compatible at -rev6, as
(engineering) revisions before that probably had some differences on the
board.
