From de76e70a8d4ea4518ec46dff2f92e2970af1d512 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 27 Aug 2018 09:43:01 -0500 Subject: arm64: use for_each_of_cpu_node iterator Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This has the side effect of defaulting to iterating using "cpu" node names in preference to the deprecated (for FDT) device_type == "cpu".

Keeping each arch aligned is a pain. The dependencies and supported targets are all slightly different. Also, a cross-compiler for each arch is needed, but really the host compiler preprocessor is perfectly fine for building dtbs. Move the build rules to a common location and remove the arch specific ones. This is done in a single step to avoid warnings about overriding rules. The build dependencies had been a mixture of 'scripts' and/or 'prepare'. These pull in several dependencies some of which need a target compiler (specifically devicetable-offsets.h) and aren't needed to build dtbs. All that is really needed is dtc, so adjust the dependencies to only be dtc. This change enables support 'dtbs_install' on some arches which were missing the target.
