    Add a nice little helper for memory bandwidth measurement on ARM CPUs
    
    This tool measures the available bandwidth into the external memory and can
    provide valuable numbers when setting up chipset settings, priority settings or
    memory timings. It's specific for ARM architecture based CPUs.

+	  Measures the available bandwidth on ARM based CPUs into the external
+	  RAM. It can help to check chipset and RAM timing settings.
+	  Note: it does not work on a different architecture than ARM!
