[U-Boot] device tree compilation problems.

Hi

I am getting DTC when compiling dts file with CONFIG_OF_CONTROL. The message says that it cannot find skeleton.dtsi though its placed in the same directory as the dts file. I notice that if i remove this line from the dts Makefile, the error disappears

$(DT_BIN): $(TOPDIR)/board/$(VENDOR)/dts/$(DEVICE_TREE).dts - cat $< | $(CPP) -P $(DTS_CPPFLAGS) - >$@.tmp - $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $@.tmp - rm $@.tmp + $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $<

Has anyone faced this issue?

Thanks Hanumant
