Lakshmi, As I mentioned before for the arm64 IMA support[1], the common parts of kexec FDT setup need to be pulled out before adding IMA support. This series is what I'd like to see done before we add any more kexec features. Arm64 and powerpc do essentially the same DT setup and the differences don't conflict. It's RFC because it's compile tested only, could use some better commit messages, and I'm only throwing it out to show what I want here. A branch is here[2].
