	 * to be copied from loading address to CONFIG_ARMV7_SECURE_BASE,
	 * which is the linking and running address for secure code.
	 * If keep the relocation entries in .rel.dyn section,
	 * "relocation offset + linking address" may locates into an
	 * address that is reserved by SoC, then will trigger data abort.
	 *
	 * The reason that move .rel._secure at the beginning, is to
	 * avoid hole in the final image.
