[PATCH v2 0/4] kbuild: Per arch/platform dtc warning levels

[Rob Herring <robh@kernel.org>]

This series adds support to set the dtc extra warning level on a per 
arch or per platform (directory really) basis.

The first version of this was just a simple per directory override for 
Samsung platforms, but Conor asked to be able to do this for all of 
riscv.

For merging, either I can take the whole thing or the riscv and samsung 
patches can go via their normal trees. The added variable will have no 
effect until merged with patch 2.
