I see these two includes from mach-versatile to plat/*.h headers: arch/arm/mach-versatile/core.c:#include arch/arm/mach-versatile/core.c:#include We can deal with those by adding ccflags-y := -I$(srctree)/arch/arm/plat-versatile/include to mach-versatile/Makefile, or we can rearrange the code. The opposite direction would be harder, but I don't see any remaining dependencies there. Arnd
