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.

682 bool "iotrace - Support for tracing I/O activity"
683 help
684 Provides an 'iotrace' command which supports recording I/O reads and
685 writes in a trace buffer in memory . It also maintains a checksum
686 of the trace records (even if space is exhausted) so that the
687 sequence of I/O accesses can be verified.
688
689 When debugging drivers it is useful to see what I/O accesses were
690 done and in what order.
691
692 Even if the individual accesses are of little interest it can be
693 useful to verify that the access pattern is consistent each time
694 an operation is performed. In this case a checksum can be used to
695 characterise the operation of a driver. The checksum can be compared
696 across different runs of the operation to verify that the driver is
697 working properly.
698
699 In particular, when performing major refactoring of the driver, where
700 the access pattern should not change, the checksum provides assurance
701 that the refactoring work has not broken the driver.
702
703 This works by sneaking into the io.h heder for an architecture and
704 redirecting I/O accesses through iotrace's tracing mechanism.
705
706 For now no commands are provided to examine the trace buffer. The
707 format is fairly simple, so 'md' is a reasonable substitute.
708
709 Note: The checksum feature is only useful for I/O regions where the
710 contents do not change outside of software control. Where this is not
711 suitable you can fall back to manually comparing the addresses. It
712 might be useful to enhance tracing to only checksum the accesses and
713 not the data read/written.
