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).

Means "this ARM build is without relocation", which is what the option does.

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.
