Hi, This v2 is just a split of the v1 series, adding support for building DT overlays to ARM build infra. The series also adds support for individual Makefiles under boot/dts hierarchy, so that per-dir flags or rules can be introduced (patch #2, #4.) Resending due to missing Frank from delivery of initial v2. Depends on the kbuild change for adding support for building .dtbo files [1].
