A .dtb is the binary (compiled) form used by the kernel. So there are several wandboard-something.dts files, each of which includes imx6.dtsi where all the common parts live. For a new imx6 device, a new board-named file similar to one of the wandboard files is necessary, and it would also include imx6.dtsi. We're pushing hard towards just using the standard dtb files from vendors, but we've got a bit of work to do before we're there. -- Ian
