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.

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

101	  or the environment variable "bootdelaykey" is specified
102	  and this string is received from console input before

820
821config CMD_IOTRACE
822	bool "iotrace - Support for tracing I/O activity"
823	help
824	  Provides an 'iotrace' command which supports recording I/O reads and
825	  writes in a trace buffer in memory . It also maintains a checksum
826	  of the trace records (even if space is exhausted) so that the
827	  sequence of I/O accesses can be verified.
828
829	  When debugging drivers it is useful to see what I/O accesses were
830	  done and in what order.
831
832	  Even if the individual accesses are of little interest it can be
833	  useful to verify that the access pattern is consistent each time
834	  an operation is performed. In this case a checksum can be used to
835	  characterise the operation of a driver. The checksum can be compared
836	  across different runs of the operation to verify that the driver is
837	  working properly.
838
839	  In particular, when performing major refactoring of the driver, where
840	  the access pattern should not change, the checksum provides assurance
841	  that the refactoring work has not broken the driver.
842
843	  This works by sneaking into the io.h heder for an architecture and
844	  redirecting I/O accesses through iotrace's tracing mechanism.
845
846	  For now no commands are provided to examine the trace buffer. The
847	  format is fairly simple, so 'md' is a reasonable substitute.
848
849	  Note: The checksum feature is only useful for I/O regions where the
850	  contents do not change outside of software control. Where this is not
851	  suitable you can fall back to manually comparing the addresses. It
852	  might be useful to enhance tracing to only checksum the accesses and
853	  not the data read/written.

1805	  MTD partitioning tool support.
1806	  It is strongly encouraged to avoid using this command
1807	  anymore along with 'sf', 'nand', 'onenand'. One can still
1808	  declare the partitions in the mtdparts environment variable
1809	  but better use the MTD stack and the 'mtd' command instead.

1831	  the size of the partitions such that 1) each partition's net size is
1832	  at least as large as the size specified in the mtdparts variable and
1833	  2) each partition starts on a good block.
