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.

711 help
712 Provides an 'iotrace' command which supports recording I/O reads and
713 writes in a trace buffer in memory . It also maintains a checksum
714 of the trace records (even if space is exhausted) so that the
715 sequence of I/O accesses can be verified.
716
717 When debugging drivers it is useful to see what I/O accesses were
718 done and in what order.
719
720 Even if the individual accesses are of little interest it can be
721 useful to verify that the access pattern is consistent each time
722 an operation is performed. In this case a checksum can be used to
723 characterise the operation of a driver. The checksum can be compared
724 across different runs of the operation to verify that the driver is
725 working properly.
726
727 In particular, when performing major refactoring of the driver, where
728 the access pattern should not change, the checksum provides assurance
729 that the refactoring work has not broken the driver.
730
731 This works by sneaking into the io.h heder for an architecture and
732 redirecting I/O accesses through iotrace's tracing mechanism.
733
734 For now no commands are provided to examine the trace buffer. The
735 format is fairly simple, so 'md' is a reasonable substitute.
736
737 Note: The checksum feature is only useful for I/O regions where the
738 contents do not change outside of software control. Where this is not
739 suitable you can fall back to manually comparing the addresses. It
740 might be useful to enhance tracing to only checksum the accesses and
741 not the data read/written.

1048 and to display it. BMP (which presumably stands for BitMaP) is a
1049 file format defined by Microsoft which supports images of various
1050 depths, formats and compression methods. Headers on the file
1051 determine the formats used. This command can be used by first loading
1052 the image into RAM, then using this command to look at it or display

1523 UBI is a software layer above MTD layer which admits use of LVM-like
1524 logical volumes on top of MTD devices, hides some complexities of
1525 flash chips like wear and bad blocks and provides some other useful
1526 capabilities. Please, consult the MTD web site for more details
