CONFIG_RELOCATABLE on powerpc means something different. On arm we start U-Boot by running it at an address != link address and _copy_ (not relocate) ourselves to the address we are linked at. On powerpc real relocation is done if CONFIG_RELOCATABLE is enabled. Hence the option you wanted to add should better have the name CONFIG_SKIP_COPY_TO_SDRAM or something like that.
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?
