Hmm.. good point. My ignorance on ppc is kicking me ;).. I will remove the SKIP_COPY part from my patch. Couple of questions:
a) Are we ok with removing dependency of ARM from "config SKIP_LOWLEVEL_INIT" in common/Kconfig (as opposed to my patch in which I moved it to arch/arm/Kconfig)?  Considering that it is used: arch/m68k/cpu/start-mcfv4e.S

b) Further am wondering if it is fine to convert ARCH_HAS_INIT_LOWLEVEL to CONFIG_ARCH_HAS_INIT_LOWLEVEL in common/Kconfig and make it arch independent?
