@ -1175,15 +1175,16 @@ When kbuild executes, the following steps are followed (roughly):
in an init section in the image. Platform code *must* copy the
blob to non-init memory prior to calling unflatten_device_tree().
To use this command, simply add *.dtb into obj-y or targets, or make
some other target depend on %.dtb
A central rule exists to create $(obj)/%.dtb from $(src)/%.dts;
architecture Makefiles do no need to explicitly write out that rule.
Example:
#arch/x86/platform/ce4100/Makefile
clean-files := *dtb.S
DTC_FLAGS := -p 1024
obj-y += foo.dtb.o
$(obj)/%.dtb: $(src)/%.dts
$(call cmd,dtc)
targets += $(dtb-y)
clean-files += *.dtb
DTC_FLAGS ?= -p 1024
