For a long time now I believe we've had some platforms that wanted to be passed, and pass on again, a single DTB. There's also been boards that have wanted to (or have been) passing what we have on. We also have the case of platforms that more constrained and so stripping information out of the DTB for U-Boot, and continuing to load the kernel DTB from somewhere else, is what they need and want. -- Tom
