+         Enable this to include exception vectors in the U-Boot image. This is
+         required if the U-Boot entry point is equal to the address of the
+         CPU reset exception vector (e.g. U-Boot as ROM loader in Qemu,
+         U-Boot booted from parallel NOR flash).
+         Disable this, if the U-Boot image is booted from DRAM (e.g. by SPL).
+         In that case the image size will be reduced by 0x500 bytes.
