This patch adds basic board support for MSM8974 which
belongs to the Snapdragon 800 family.
For now, just support a basic machine with device tree.

That's odd. If this is support for an SoC, why not a *.dtsi file rather
than *.dts?

I am not sure why I would need a dtsi if I am just adding the 1 file for 
the SoC support ?

Thanks,

The .dts file should be for a specific board, not a general SoC.  Note
the names of the other board .dts files for MSM.  We'll probably want
a msm8974.dtsi at some point, though.
