Not really, although I haven't used a skeleton file on mainline. One
thing to check is that you have a .dtsi extension.
The lines above are running the .dts file through the C proprocessor
to create a tmp file, which is then compiled. It is only really used
to get the name of the SOC's device tree include file - see the
definition of DTS_CPPFLAGS.
The tmp file should be in the same directory - check the file it
produces and see what is wrong with it. The reason for using a tmp
file is that people can check the resulting post-processed input to
dtc. I wonder if the # signs in the file are confusing the
preprocessor (at the time I wondered why they didn't). We should
perhaps add sed into the mix :-(
