As for other architectures, arch/*/boot/dts/Makefile builds DTB by using the dtb-y syntax. In contrast, arch/powerpc/boot/dts/(fsl/)Makefile does nothing unless CONFIG_OF_ALL_DTBS is defined. Instead, arch/powerpc/boot/Makefile builds DTB on demand. You need to add DTB to 'targets' explicitly so .*.cmd files are included.

New tool doesn't support any PPC405/PPC440 new designs. These platforms are no longer supported and tested. PowerPC 405/440 port is orphan from 2013 by commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership") that's why it is time to remove the support fot these platforms.

This can lead to confusing errors, eg: $ make clean $ touch install $ make install make: 'install' is up to date. $ Fix it by adding them to the PHONY variable which is marked phony in the top-level Makefile, or in scripts/Makefile.build for the boot Makefile.

It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m) I think this makes more sense because a host program is always a host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.

According to Documentation/process/changes.rst, the current minimal supported version of binutils is 2.21 so you can assume the 'D' option is always supported. Not only GNU ar but also llvm-ar supports it. With the 'D' option hard-coded, there is no more user of ar-option or KBUILD_ARFLAGS.
