Masahiro Yamada f55813b4d8 kbuild: dtbinst: remove unnecessary __dtbs_install_prep target
Since commit 5399eb9b39 ("dtbsinstall: don't move target directory
out of the way"), the target __dtbs_install_prep is invoked just for
creating the install directory, but all the necessary directories
are automatically created by:
   cmd_dtb_install = mkdir -p $(2); cp $< $(2)

Russell King 5399eb9b39 dtbsinstall: don't move target directory out of the way
No other kernel installation target moves the target directory out of
the way, even deleting an old version of it.  These are destructive
operations, ones which the kernel build system should not be making.

This behaviour prevents being able to do:

	make install INSTALL_PATH=/some/path/boot
	make dtbs_install INSTALL_DTBS_PATH=/some/path/boot

As it causes the boot directory containing the kernel installed in
step 1 to be moved to /some/path/boot.old.  Things get even more fun
if you do:

	make install dtbs_install INSTALL_PATH=/some/path/boot INSTALL_DTBS_PATH=/some/path/boot

The kernel gets installed into /some/path/boot, then the directory gets
renamed to /some/path/boot.old, and a new directory created to hold the
dtbs.  Even more fun if you supply -j2 when we end up with races in
make.

Remove this behaviour.

If this behaviour is required at installation time, this should be
done by the installation external to the kernel makefiles, just like
it would be done for 'make modules_install'.

Masahiro Yamada 5f655c7a4c kbuild: include $(src)/Makefile rather than $(obj)/Makefile
This commit actually has no impact because $(src) and $(obj) point
to the same path, but $(src)/Makefile looks better when we include
source files.

Masahiro Yamada 7aacad53ae kbuild: use relative path to include Makefile
The "MAKEFLAGS += --include-dir=$(srctree)" line in the top Makefile
allows us to do this.

Robert Richter 323a028d39 dts, kbuild: Implement support for dtb vendor subdirs
This patch adds support of vendor sub directories for dtb files.
Subdirectories can be specified in $(dts-dirs). Kbuild traverses over
all directories while building and installing dtb files. The directory
tree is also reflected in the install path.

Robert Richter 9fb5e53722 dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst
Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be
defined. Another advantage is that install goals are not encoded in
targets anymore (%.dtb_dtbinst_).
