I suppose we can do this later, but since this patch has the C files split into separate board and carrier code, I'd also expect the .dts files to be split up in the same way.

I initially tried exactly that, but since the .dts files are compiled a bit different in u-boot than in the linux kernel it's not as easy as doing a simple include. I'm planning to split them up later on, but I first have to familiarize myself with the build process for dts in u-boot.
For now I would wish to get this included as is, to get Colibri T20 some public visibility as a working Tegra platform, so others could take this board into account when making changes to the Tegra 20 common platform.
Thanks, Lucas

Oh right. Perhaps we should start to rely on the latest dtc, which is able to co-exist with the regular C pre-processor, and can support a bunch of include paths or something...

Sure.
