There is no section called '.dtb' in U-boot linker script, instead one generated by build script is named '.dtb.init.rodata'. Unless we add '-j .dtb.init.rodata' device-tree blob will not be copied to binary. > PLATFORM_CPPFLAGS += -G 0 $(PF_ABICALLS) $(PF_PIC) > diff --git a/arch/mips/dts/.gitignore b/arch/mips/dts/.gitignore > new file mode 100644 > index 0000000..b60ed20 > --- /dev/null > +++ b/arch/mips/dts/.gitignore > @@ -0,0 +1 @@ > +*.dtb > diff --git a/arch/mips/dts/Makefile b/arch/mips/dts/Makefile > new file mode 100644 > index 0000000..47b6eb5 > --- /dev/null > +++ b/arch/mips/dts/Makefile > @@ -0,0 +1,16 @@ > +# > +# SPDX-License-Identifier: GPL-2.0+ > +# > + > +dtb-y += > + > +targets += $(dtb-y) > + > +# Add any required device tree compiler flags here > +DTC_FLAGS += > + > +PHONY += dtbs > +dtbs: $(addprefix $(obj)/, $(dtb-y)) > + @: > + > +clean-files := *.dtb > diff --git a/arch/mips/dts/skeleton.dtsi b/arch/mips/dts/skeleton.dtsi > new file mode 100644 > index 0000000..24ee6c3 > --- /dev/null > +++ b/arch/mips/dts/skeleton.dtsi > @@ -0,0 +1,23 @@ > +/* > + * Skeleton device tree; the bare minimum needed to boot; just include and > + * add a compatible value.
