What would we do with this if we found it in a hwpack?
I don't know; I need more handson experience with DT to tell. It might be that we don't need this this cycle because the DT will be embedded in the zImage. Otherwise, we'd have to mkimage it along uImage and uInitrd, probably in a uFdt or something like that, and then change the boot script to pass it to the kernel.
I'd prefer if we could keep the kernel and fdt images separate as much as possible. In theory, the fdt should be updated far less often than the kernel. If we really need to bundle the kernel and fdt together then there is generic support for that in the kernel build system already.
More importantly, you might want to update the fdt files on a different cycle than the kernel. If you have a new slightly different configuration in a new machine you want to support, it may be easier to add a new file somewhere than doing a respin of all the kernel packages when they contain the dtc source. I would not see much of a problem with always shipping all trees with the kernel package, even if they never change.
