Changes in v4 from the cover letter
- Make dtbs and %.dtb rules depend on arch/$ARCH/boot/dts path rather than CONFIG_OF_EARLY_FLATTREE
- Fix install path missing kernel version for dtbs_install
- Fix "make CONFIG_OF_ALL_DTBS=y" for arches like ARM which selectively enable CONFIG_OF (and therefore dtc)

Cover letter [PATCH v4 0/9] Devicetree build consolidation
This series addresses a couple of issues I have with building dts files.
First, the ability to build all the dts files in the tree. This has been supported on most arches for some time with powerpc being the main exception. The reason powerpc wasn't supported was it needed a change in the location built dtb files are put.
Secondly, it's a pain to acquire all the cross-compilers needed to build dtbs for each arch. There's no reason to build with the cross compiler and the host compiler is perfectly fine as we only need the pre-processor.
I started addressing just those 2 problems, but kept finding small differences such as target dependencies and dtbs_install support across architectures. Instead of trying to align all these, I've consolidated the build targets moving them out of the arch makefiles.
I'd like to take the series via the DT tree.
PPC maintainers, really need you review/ack on this especially patch 1.

v4:
- Make dtbs and %.dtb rules depend on arch/$ARCH/boot/dts path rather than CONFIG_OF_EARLY_FLATTREE
- Fix install path missing kernel version for dtbs_install
- Fix "make CONFIG_OF_ALL_DTBS=y" for arches like ARM which selectively enable CONFIG_OF (and therefore dtc)
v3:
- Rework dtc dependency to avoid 2 entry paths to scripts/dtc/. Essentially, I copied 'scripts_basic'.
- Add missing scripts_basic dependency for dtc and missing PHONY tag.
- Drop the '|' order only from dependencies
- Drop %.dtb.S and %.dtb.o as top-level targets
- PPC: remove duplicate mpc5200 dtbs from image-y targets
v2:
- Fix $arch/boot/dts path check for out of tree builds
- Fix dtc dependency for building built-in dtbs
- Fix microblaze built-in dtb building
- Add dtbs target for microblaze
