+ * "-mword-relocations" to compile and "-pie" to link into the
+ * final image. We do not need the relocation entries for secure
+ * code, because secure code will not be relocated, it only needs
+ * 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.
