== Device Tree == * Posted the patch that builds .dtb files for boards enabled by config option. Got good suggestion from Rob Herring to improve. Will re-spin soon. * Tried to play linux-linaro-natty tree a little bit to get .dtb file built in linux-image-*.deb. But I can not post patch for merging until John Rigby sync this tree with Nico's latest kernel tree. * Will work on l-m-c to get .dtb installed on boot partition. == Misc == * Read the thread of Linus' complaint on messy ARM platform codes. -- Regards, Shawn

[PATCH] arm/dt: Add a make rule to build dtb for enabled platform

by Shawn Guo

It's based on commit fe8e6d0b0e601ca0a63fe768d4b812d5a45a9da7 "arm/dt: Add dtb make rule" from Rob Herring. With 'make ARCH=arm dtb', it builds Device Tree Blobs for those platforms enabled by CONFIG. Signed-off-by: Shawn Guo <shawn.guo(a)linaro.org> --- This patch works against Linaro kernel tree. But it needs to go through mainline review before it gets applied. arch/arm/Makefile | 3 +++ arch/arm/boot/Makefile | 14 ++++++++++++++ 2 files changed, 17 insertions(+), 0 deletions(-) diff --git a/arch/arm/Makefile b/arch/arm/Makefile index d51ab6c..7fd2af9 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -292,6 +292,9 @@ zinstall uinstall install: vmlinux %.dtb: $(Q)$(MAKE) $(build)=$(boot) MACHINE=$(MACHINE) $(boot)/$@ +dtb: + $(Q)$(MAKE) $(build)=$(boot) MACHINE=$(MACHINE) $(boot)/$@ + # We use MRPROPER_FILES and CLEAN_FILES now archclean: $(Q)$(MAKE) $(clean)=$(boot) diff --git a/arch/arm/boot/Makefile b/arch/arm/boot/Makefile index 08fc37f..dcea984 100644 --- a/arch/arm/boot/Makefile +++ b/arch/arm/boot/Makefile @@ -63,6 +63,20 @@ endif $(obj)/%.dtb: $(src)/dts/%.dts $(call cmd,dtc) +dtb-$(CONFIG_MACH_HARMONY) += tegra-harmony.dtb +dtb-$(CONFIG_MACH_MX51_BABBAGE) += mx51-babbage.dtb +dtb-$(CONFIG_MACH_MX51_EFIKAMX) += genesi-efikamx.dtb +dtb-$(CONFIG_MACH_MX51_EFIKASB) += genesi-efikasb.dtb +dtb-$(CONFIG_MACH_MX53_LOCO) += mx53-loco.dtb +dtb-$(CONFIG_MACH_OMAP3_BEAGLE) += omap3-beagle.dtb +dtb-$(CONFIG_MACH_OMAP4_PANDA) += omap4-panda.dtb +dtb-$(CONFIG_MACH_OVERO) += omap3-overo.dtb +dtb-$(CONFIG_MACH_SMDKV310) += exynos4-smdkv310.dtb +dtb-$(CONFIG_ARCH_VERSATILE_PB) += versatile-pb.dtb +dtb-$(CONFIG_MACH_VERSATILE_AB) += versatile-ab.dtb + +$(obj)/dtb: $(addprefix $(obj)/, $(dtb-y)) + quiet_cmd_uimage = UIMAGE $@ cmd_uimage = $(CONFIG_SHELL) $(MKIMAGE) -A arm -O linux -T kernel \ -C none -a $(LOADADDR) -e $(STARTADDR) \ -- 1.7.1
