There is at least a possibility to avoid relocation without introducing
the CONFIG_SYS_SKIP_ARM_RELOCATION flag; set CONFIG_SKIP_LOWLEVEL_INIT
and adjust CONFIG_SYS_TEXT_BASE to be the base address where your code
will be located. It is a two-round process (you need a first run with
the 'wrong' CONFIG_SYS_TEXT_BASE in order to find its 'right' value) and
will work only for a given board variant (same available RAM amount
always) but might be enough to cover the use case(s) you are looking for?
