7 	  Enable U-Boot's command-line functions. This provides a means
8 	  to enter commands into U-Boot for a wide variety of purposes. It
9 	  also allows scripts (containing commands) to be executed.
10 	  Various commands and command categorys can be indivdually enabled.

796 	  writes in a trace buffer in memory . It also maintains a checksum
797 	  of the trace records (even if space is exhausted) so that the
798 	  sequence of I/O accesses can be verified.
799 
800 	  When debugging drivers it is useful to see what I/O accesses were
801 	  done and in what order.
802 
803 	  Even if the individual accesses are of little interest it can be
804 	  useful to verify that the access pattern is consistent each time
805 	  an operation is performed. In this case a checksum can be used to
806 	  characterise the operation of a driver. The checksum can be compared
807 	  across different runs of the operation to verify that the driver is
808 	  working properly.
809 
810 	  In particular, when performing major refactoring of the driver, where
811 	  the access pattern should not change, the checksum provides assurance
812 	  that the refactoring work has not broken the driver.
813 
814 	  This works by sneaking into the io.h heder for an architecture and
815 	  redirecting I/O accesses through iotrace's tracing mechanism.
816 
817 	  For now no commands are provided to examine the trace buffer. The
818 	  format is fairly simple, so 'md' is a reasonable substitute.
819 
820 	  Note: The checksum feature is only useful for I/O regions where the
821 	  contents do not change outside of software control. Where this is not
822 	  suitable you can fall back to manually comparing the addresses. It
823 	  might be useful to enhance tracing to only checksum the accesses and
824 	  not the data read/written.
