GCC can be built with different defaults. The -mno-string option guarantees that string instructions will not be generated. I wrote some half-year ago that I too need this option for my GCC version. In theory, -mcpu=8540 implies -mno-string. In the real world, at least some GCC versions generate string instructions if -mno-string is not specified explicitly, and you can discover this only when the U-Boot crashes in run-time.
