I think the board should be named here, so we could take some code branches based on the board, if it would have bad wiring for example. The device tree wiki says: "The first string in the list specifies the exact device that the node represents" http://devicetree.org/Device_Tree_Usage#Understanding_the_compatible_Property The exact device here is the board not the SoC.

Add device tree files for Broadcom Northstar based SVKs. Since the bcm5301x.dtsi already exists, all that is necessary is the dts files to enable the UARTs. With these files, the SVKs are able to boot to shell.
