This does not lose said feature. You can still disable relocation altogether by defining CONFIG_SKIP_RELOCATE_UBOOT (watch out then; you're responsible for linking u-boot for its intended *final* location). > Another question here, why the original implementation now call as > CONFIG_SYS_ARM_WITHOUT_RELOC? Means "this ARM build is without relocation", which is what the option does. > I think CONFIG_SYS_ARM_WITH_RELOC is correct, for it do the relocation > at the very begining. :-p Read the code carefully. You'll see that the old code is used when CONFIG_SYS_ARM_WITHOUT_RELOC is defined, and the new (reloc) code used when CONFIG_SYS_ARM_WITHOUT_RELOC is not define. > Best regards, > Lei Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
