c6x: make dsk6455 the default config C6X had no defconfig, so DSK6455 is as good as any. Signed-off-by: Mark Salter <msalter@redhat.com> 2012-10-04 01:39:12 +04:00			`KBUILD_DEFCONFIG := dsk6455_defconfig`

c6x: Makefile: Add -D__linux__ 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.

c6x: use new common dtc rule 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.
