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
12 substantially to the size of U-Boot.

968 sequence of I/O accesses can be verified.
969
970 When debugging drivers it is useful to see what I/O accesses were
971 done and in what order.
972
973 Even if the individual accesses are of little interest it can be
974 useful to verify that the access pattern is consistent each time
975 an operation is performed. In this case a checksum can be used to
976 characterise the operation of a driver. The checksum can be compared
977 across different runs of the operation to verify that the driver is
978 working properly.
979
980 In particular, when performing major refactoring of the driver, where
981 the access pattern should not change, the checksum provides assurance
982 that the refactoring work has not broken the driver.
983
984 This works by sneaking into the io.h heder for an architecture and
985 redirecting I/O accesses through iotrace's tracing mechanism.
986
987 For now no commands are provided to examine the trace buffer. The
988 format is fairly simple, so 'md' is a reasonable substitute.
989
990 Note: The checksum feature is only useful for I/O regions where the
991 contents do not change outside of software control. Where this is not
992 suitable you can fall back to manually comparing the addresses. It
993 might be useful to enhance tracing to only checksum the accesses and
994 not the data read/written.
