There is nothing arch specific about building dtb files other than their
location under /arch/*/boot/dts/. 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.Acked-by: Will Deacon

Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.For some reason, LDFLAGS was not renamed.
Using a well-known variable like LDFLAGS may result in accidental
override of the variable.Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.I did not touch Makefiles under tools/ since the tools build system
is a different world.Signed-off-by: Masahiro Yamada

c6x depends on the macro '_BIG_ENDIAN' being defined or not
to correctly select or define endian-specific macros, structures
or pieces of code.This macro is predefined by the compiler but sparse knows nothing
about it and thus may pre-process files differently from what
gcc would.Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian
kernel, like GCC would have done.To: Mark Salter

As kbuild document & commit 6588169d51 says: KBUILD_CFLAGS_MODULE is
used to add arch-specific options for $(CC). From commandline,
CFLAGS_MODULE shall be used.
Doesn't have any functional change, but just follow kbuild rules.Signed-off-by: Cao jin

For gcc5 c6x raw compiler, at present, it may not define __linux__, so
c6x kernel still needs to define __linux__ just like another archs have
done. The related error:CC [M] fs/coda/psdev.o

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes c6x to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.This requires moving parts of arch/c6x/boot/Makefile into newly created
arch/c6x/boot/dts/Makefile, and updating arch/c6x/Makefile to call the
new Makefile. linked_dtb.S is also moved into boot/dts/ since it's used
by rules that were moved.Acked-by: Mark Salter

C6X had no defconfig, so DSK6455 is as good as any.
