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.
11 Depending on the number of commands enabled, this can add

757 help
758 Provides an 'iotrace' command which supports recording I/O reads and
759 writes in a trace buffer in memory . It also maintains a checksum
760 of the trace records (even if space is exhausted) so that the
761 sequence of I/O accesses can be verified.
762
763 When debugging drivers it is useful to see what I/O accesses were
764 done and in what order.
765
766 Even if the individual accesses are of little interest it can be
767 useful to verify that the access pattern is consistent each time
768 an operation is performed. In this case a checksum can be used to
769 characterise the operation of a driver. The checksum can be compared
770 across different runs of the operation to verify that the driver is
771 working properly.
772
773 In particular, when performing major refactoring of the driver, where
774 the access pattern should not change, the checksum provides assurance
775 that the refactoring work has not broken the driver.
776
777 This works by sneaking into the io.h heder for an architecture and
778 redirecting I/O accesses through iotrace's tracing mechanism.
779
780 For now no commands are provided to examine the trace buffer. The
781 format is fairly simple, so 'md' is a reasonable substitute.
782
783 Note: The checksum feature is only useful for I/O regions where the
784 contents do not change outside of software control. Where this is not
785 suitable you can fall back to manually comparing the addresses. It
786 might be useful to enhance tracing to only checksum the accesses and
787 not the data read/written.
