From: Stephen Warren <[email protected]> The current rules have the .dtb files build in a different directory from the .dts files. This patch changes xtensa to use the generic dtb rule which builds .dtb files in the same directory as the source .dts.
This requires moving parts of arch/xtensa/boot/Makefile into newly created arch/xtensa/boot/dts/Makefile, and updating arch/xtensa/Makefile to call the new Makefile. Cc: Chris Zankel <[email protected]> Cc: Max Filippov <[email protected]> Cc: [email protected] Signed-off-by: Stephen Warren <[email protected]> --- This patch applies recent dtc-rule-related changes to the xtensa arch. They couldn't be applied along with the similar changes for other archs due to dependencies on other xtensa changes. This should apply OK now to Linus's tree, or for 3.9. Note: I have not tested this recently. arch/xtensa/Makefile | 4 ++-- arch/xtensa/boot/Makefile | 12 ------------ arch/xtensa/boot/dts/Makefile | 15 +++++++++++++++ 3 files changed, 17 insertions(+), 14 deletions(-) create mode 100644 arch/xtensa/boot/dts/Makefile diff --git a/arch/xtensa/Makefile b/arch/xtensa/Makefile index 0aa7270..48c1a5b 100644 --- a/arch/xtensa/Makefile +++ b/arch/xtensa/Makefile @@ -88,7 +88,7 @@ core-y += $(buildvar) $(buildplf) libs-y += arch/xtensa/lib/ $(LIBGCC) ifneq ($(CONFIG_BUILTIN_DTB),"") -core-$(CONFIG_OF) += arch/xtensa/boot/ +core-$(CONFIG_OF) += arch/xtensa/boot/dts/ endif boot := arch/xtensa/boot @@ -101,7 +101,7 @@ zImage: vmlinux $(Q)$(MAKE) $(build)=$(boot) $@ %.dtb: - $(Q)$(MAKE) $(build)=$(boot) $(boot)/$@ + $(Q)$(MAKE) $(build)=$(boot)/dts $(boot)/dts/$@ define archhelp @echo '* zImage - Compressed kernel image (arch/xtensa/boot/images/zImage.*)' diff --git a/arch/xtensa/boot/Makefile b/arch/xtensa/boot/Makefile index 818647e..64ffc4b 100644 --- a/arch/xtensa/boot/Makefile +++ b/arch/xtensa/boot/Makefile @@ -25,18 +25,6 @@ bootdir-$(CONFIG_XTENSA_PLATFORM_ISS) += boot-elf bootdir-$(CONFIG_XTENSA_PLATFORM_XT2000) += boot-redboot boot-elf boot-uboot bootdir-$(CONFIG_XTENSA_PLATFORM_XTFPGA) += boot-redboot boot-elf boot-uboot - -BUILTIN_DTB := $(patsubst "%",%,$(CONFIG_BUILTIN_DTB)).dtb.o -ifneq ($(CONFIG_BUILTIN_DTB),"") -obj-$(CONFIG_OF) += $(BUILTIN_DTB) -endif - -# Rule to build device tree blobs -$(obj)/%.dtb: $(src)/dts/%.dts FORCE - $(call if_changed_dep,dtc) - -clean-files := *.dtb.S - zImage Image: $(bootdir-y) $(bootdir-y): $(addprefix $(obj)/,$(subdir-y)) \ diff --git a/arch/xtensa/boot/dts/Makefile b/arch/xtensa/boot/dts/Makefile new file mode 100644 index 0000000..5f711bb --- /dev/null +++ b/arch/xtensa/boot/dts/Makefile @@ -0,0 +1,15 @@ +# +# arch/xtensa/boot/dts/Makefile +# +# This file is subject to the terms and conditions of the GNU General Public +# License.
