|     ARM: dt: change .dtb build rules to build in dts directory
|
|     The current rules have the .dtb files build in a different directory
|     from the .dts files. The only reason for this is that it was what
|     PowerPC has done historically. This patch changes ARM to use the generic
|     dtb rule which builds .dtb files in the same directory as the source .dts.
