This series addresses a couple of issues I have with building dts files. First, the ability to build all the dts files in the tree. This has been supported on most arches for some time with powerpc being the main exception. The reason powerpc wasn't supported was it needed a change in the location built dtb files are put. Secondly, it's a pain to acquire all the cross-compilers needed to build dtbs for each arch. There's no reason to build with the cross compiler and the host compiler is perfectly fine as we only need the pre-processor. I started addressing just those 2 problems, but kept finding small differences such as target dependencies and dtbs_install support across architectures. Instead of trying to align all these, I've consolidated the build targets moving them out of the arch makefiles. I'd like to take the series via the DT tree.
