Hi, This series introduces devicetree overlay building support for ARM platforms. The .dtbo target is introduced globally, then makefile changes for both arm32/64 for supporting the .dtbo target, changes to support sub-dir makefile flags, and finally adding the DTC flags override for TI platforms, as that is where we want to introduce the DT overlay support initially. The ARM makefile changes for supporting DTS sub-makefiles don't look too clean, but that was the only way I could figure out how to get it done. -Tero -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
