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.

68	  This option enables stopping (aborting) of the automatic
69	  boot feature only by issuing a specific input key or

81	  output indicating that autoboot is in progress.
82
83	  Note that this define is used as the (only) argument to a

825config CMD_IOTRACE

827	help
828	  Provides an 'iotrace' command which supports recording I/O reads and
829	  writes in a trace buffer in memory . It also maintains a checksum
830	  of the trace records (even if space is exhausted) so that the
831	  sequence of I/O accesses can be verified.
832
833	  When debugging drivers it is useful to see what I/O accesses were
834	  done and in what order.
835
836	  Even if the individual accesses are of little interest it can be
837	  useful to verify that the access pattern is consistent each time
838	  an operation is performed. In this case a checksum can be used to
839	  characterise the operation of a driver. The checksum can be compared
840	  across different runs of the operation to verify that the driver is
841	  working properly.
842
843	  In particular, when performing major refactoring of the driver, where
844	  the access pattern should not change, the checksum provides assurance
845	  that the refactoring work has not broken the driver.
846
847	  This works by sneaking into the io.h heder for an architecture and
848	  redirecting I/O accesses through iotrace's tracing mechanism.
849
850	  For now no commands are provided to examine the trace buffer. The
851	  format is fairly simple, so 'md' is a reasonable substitute.
852
853	  Note: The checksum feature is only useful for I/O regions where the
854	  contents do not change outside of software control. Where this is not
855	  suitable you can fall back to manually comparing the addresses. It
856	  might be useful to enhance tracing to only checksum the accesses and
857	  not the data read/written.

1809	  MTD partitioning tool support.
1810	  It is strongly encouraged to avoid using this command
1811	  anymore along with 'sf', 'nand', 'onenand'. One can still
1812	  declare the partitions in the mtdparts environment variable
1813	  but better use the MTD stack and the 'mtd' command instead.

1834	  This command will modify the existing mtdparts variable by increasing
1835	  the size of the partitions such that 1) each partition's net size is
1836	  at least as large as the size specified in the mtdparts variable and
1837	  2) each partition starts on a good block.
