Build the dtb file for these platfroms with __symbol__ information included. This will reduce the size of the dtb (and resident memory usage) in exchange for allowing more types of overlays to be applied to the dtb file prior to passing it to Linux and additional functionality within the kernel when OF_OVERLAY is enabled.

I would suggest that the dra76 series be respun to include a hunk like this at least as well, and if there's another Beagle X15 patch, that too. Russell, per some of our conversations, something like would also be needed as part of using overlays to solve some of the problems with Hummingboard, etc. --- arch/arm/boot/dts/Makefile | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 4b17f35dc9a7..6f98422ca00e 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1063,3 +1063,17 @@ dtb-$(CONFIG_OF_ALL_DTBS) := $(patsubst $(dtstree)/%.dts,%.dtb, $(wildcard $(dts always := $(dtb-y) clean-files := *.dtb + +# enable creation of __symbols__ node +DTC_FLAGS_am335x-bone += -@ +DTC_FLAGS_am335x-boneblack += -@ +DTC_FLAGS_am335x-boneblack-wireless += -@ +DTC_FLAGS_am335x-boneblue += -@ +DTC_FLAGS_am335x-bonegreen += -@ +DTC_FLAGS_am335x-bonegreen-wireless += -@ +DTC_FLAGS_am57xx-beagle-x15 += -@ +DTC_FLAGS_am57xx-beagle-x15-revb1 += -@ +DTC_FLAGS_dra7-evm += -@ +DTC_FLAGS_dra72-evm += -@ +DTC_FLAGS_dra72-evm-revc += -@ +DTC_FLAGS_dra71-evm += -@ -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
