The filename msmcopper.dts does not describe a target, split these up to create SoC specific (.dtsi) and board specific (.dts) device tree source files. The board specific files need to include the SoC file and can selectively specify the devices that are not present or supported. Update the makefile to generate all board variants of appended DTB zImage files or allow for a specific variant to be generated using the DTS_NAME override.
