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.

721 help
722 Provides an 'iotrace' command which supports recording I/O reads and
723 writes in a trace buffer in memory . It also maintains a checksum
724 of the trace records (even if space is exhausted) so that the
725 sequence of I/O accesses can be verified.
726
727 When debugging drivers it is useful to see what I/O accesses were
728 done and in what order.
729
730 Even if the individual accesses are of little interest it can be
731 useful to verify that the access pattern is consistent each time
732 an operation is performed. In this case a checksum can be used to
733 characterise the operation of a driver. The checksum can be compared
734 across different runs of the operation to verify that the driver is
735 working properly.
736
737 In particular, when performing major refactoring of the driver, where
738 the access pattern should not change, the checksum provides assurance
739 that the refactoring work has not broken the driver.
740
741 This works by sneaking into the io.h heder for an architecture and
742 redirecting I/O accesses through iotrace's tracing mechanism.
743
744 For now no commands are provided to examine the trace buffer. The
745 format is fairly simple, so 'md' is a reasonable substitute.
746
747 Note: The checksum feature is only useful for I/O regions where the
748 contents do not change outside of software control. Where this is not
749 suitable you can fall back to manually comparing the addresses. It
750 might be useful to enhance tracing to only checksum the accesses and
751 not the data read/written.

1465 the size of the partitions such that 1) each partition's net size is
1466 at least as large as the size specified in the mtdparts variable and

1562 UBI is a software layer above MTD layer which admits use of LVM-like
1563 logical volumes on top of MTD devices, hides some complexities of
1564 flash chips like wear and bad blocks and provides some other useful
1565 capabilities. Please, consult the MTD web site for more details
1566 (www.linux-mtd.infradead.org). Activate this option if you want
