[PATCH 0/6] dts, kbuild: Implement support for dtb vendor subdirs

[Robert Richter]

From: Robert Richter <rrichter at cavium.com>

For arm64 we want to put dts files into vendor's subdirectories from
the beginning. This patch set implements this. As this is a generic
kbuild implementation, vendor subdirs will be also available for
arch/arm and other architectures. The subdirectory tree is also
reflected in the install path.

A new makefile variable dts-dirs is introduced to point to dts
subdirs. This variable is used by kbuild for building and installation
of dtb files.

A dts Makefile looks now as follows:

----
dtb-$(CONFIG_...) += some_file_1.dtb
dtb-$(CONFIG_...) += some_file_2.dtb

dts-dirs          += dir_vendor_a
dts-dirs          += dir_vendor_b

# come always afterwards:
always         := $(dtb-y)
subdir-y       := $(dts-dirs)
clean-files    := *.dtb
----

This patches also introduces the dtbs_install make target for
arm64. Install rules are moved to Makefile.dtbinst using the same
style and calling convention like for modinst and fwinst.

Robert Richter (6):
  dts, arm64: Add dtbs_install make target
  dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst
  dts, arm/arm64: Remove dtbs build rules in sub-makes
  dts, kbuild: Implement support for dtb vendor subdirs
  dts, arm64: Move dts files to vendor subdirs
  dts, arm: Remove $(MACHINE) variable from dtbs make recipes
