Copy-paste stuff ... boards using rockchip,boardname instead of
vendor,boardname for their compatible.

I do remember us noticing this a number of times on some boards
and requesting fixes, but looks like some slipped through.

So I guess Tim is suggesting changing the compatible, but with boards
being merged a while ago, this would break backwards compatibility.
So I guess both the Orange and Banana Pies will need to live with that.
