I thought it was useful, primarily in testing your Freescale DMA patches. I'm not sure how much this test stresses the memory chips (as compared to Linux). If it is reasonably close, then I think it is a very useful piece of code to have. Linux is a lot more code to wade through compared to U-Boot when things aren't working.
