The skov-arm9cpu looks like it already runs first stage without at91bootstrap?

I have only worked on SAMA5D3 and SAMA5D2. Of course, I'd like to see board code in AT91 replaced with DT-enabled/multi-image-compatible code, but I don't think it will happen. I don't think the maintenance burden is high, so I'd just leave it as is. If it bitrots and people complain, we can nudge them into the right direction. > I am happy to type the patches - and verify that the boards I have works. Great. Looking forward to more boards in at91_multi_defconfig.
