Well, it does mean that the RX51 was not adapted for the relocation... You should take care that the initial stackpointer (check for CONFIG_SYS_INIT_SP_ADDR) is set to a a range into RAM (or internal RAM, if any) and it is not overwritten by other parts (where is your TEXT code ?). Move all first initialization into board_early_init_f, if any.
