That is something we don't support with the kernel, and would be insane to do so - it would mean that the very dumb decompressor would have to relocate not only the dtb image, but also the initrd image to some other part of memory. It moves the appended dtb image along with the rest of the zImage as one complete blob, but that doesn't work so well for an appended initrd. It will also be rather slow. So I'd like to continue my discouragement of this entire approach and say that kexec-tools should *not* add support for an appended DTB nor an appended initrd. The kernel build process gives you the kernel image and dtb file. The appended-dtb image support that we have in the kernel is for backwards compatibility with non-DT aware boot loaders that only know how to deal with one or two images at boot time. -- Russell King
