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.

696 bool "iotrace - Support for tracing I/O activity"
697 help
698 Provides an 'iotrace' command which supports recording I/O reads and
699 writes in a trace buffer in memory . It also maintains a checksum
700 of the trace records (even if space is exhausted) so that the
701 sequence of I/O accesses can be verified.
702
703 When debugging drivers it is useful to see what I/O accesses were
704 done and in what order.
705
706 Even if the individual accesses are of little interest it can be
707 useful to verify that the access pattern is consistent each time
708 an operation is performed. In this case a checksum can be used to
709 characterise the operation of a driver. The checksum can be compared
710 across different runs of the operation to verify that the driver is
711 working properly.
712
713 In particular, when performing major refactoring of the driver, where
714 the access pattern should not change, the checksum provides assurance
715 that the refactoring work has not broken the driver.
716
717 This works by sneaking into the io.h heder for an architecture and
718 redirecting I/O accesses through iotrace's tracing mechanism.
719
720 For now no commands are provided to examine the trace buffer. The
721 format is fairly simple, so 'md' is a reasonable substitute.
722
723 Note: The checksum feature is only useful for I/O regions where the
724 contents do not change outside of software control. Where this is not
725 suitable you can fall back to manually comparing the addresses. It
726 might be useful to enhance tracing to only checksum the accesses and
727 not the data read/written.
