Both arm64 and powerpc do essentially the same FDT /chosen setup for kexec. The differences are either omissions that arm64 should have or additional properties that will be ignored. The setup code can be combined and shared by both powerpc and arm64. The differences relative to the arm64 version: - If /chosen doesn't exist, it will be created (should never happen). - Any old dtb and initrd reserved memory will be released. - The new initrd and elfcorehdr are marked reserved. - "linux,booted-from-kexec" is set. The differences relative to the powerpc version: - "kaslr-seed" and "rng-seed" may be set. - "linux,elfcorehdr" is set. - Any existing "linux,usable-memory-range" is removed. Combine the code for setting up the /chosen node in the FDT and updating the memory reservation for kexec, for powerpc and arm64, in of_kexec_alloc_and_setup_fdt() and move it to "drivers/of/kexec.c".
