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.

67	help
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

101	  or the environment variable "bootdelaykey" is specified
102	  and this string is received from console input before
103	  autoboot starts booting, U-Boot gives a command prompt. The

124	  This option allows for the boot sequence to be interrupted
125	  by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".

796	help
797	  Provides an 'iod' command to display I/O space and an 'iow' command

799	  checking the state of devices during boot when debugging device
800	  drivers, etc.
801
802config CMD_IOTRACE
803	bool "iotrace - Support for tracing I/O activity"
804	help
805	  Provides an 'iotrace' command which supports recording I/O reads and
806	  writes in a trace buffer in memory . It also maintains a checksum
807	  of the trace records (even if space is exhausted) so that the
808	  sequence of I/O accesses can be verified.
809
810	  When debugging drivers it is useful to see what I/O accesses were
811	  done and in what order.
812
813	  Even if the individual accesses are of little interest it can be
814	  useful to verify that the access pattern is consistent each time
815	  an operation is performed. In this case a checksum can be used to
816	  characterise the operation of a driver. The checksum can be compared
817	  across different runs of the operation to verify that the driver is
818	  working properly.
819
820	  In particular, when performing major refactoring of the driver, where
821	  the access pattern should not change, the checksum provides assurance
822	  that the refactoring work has not broken the driver.
823
824	  This works by sneaking into the io.h heder for an architecture and
825	  redirecting I/O accesses through iotrace's tracing mechanism.
826
827	  For now no commands are provided to examine the trace buffer. The
828	  format is fairly simple, so 'md' is a reasonable substitute.
829
830	  Note: The checksum feature is only useful for I/O regions where the
831	  contents do not change outside of software control. Where this is not
832	  suitable you can fall back to manually comparing the addresses. It
833	  might be useful to enhance tracing to only checksum the accesses and
834	  not the data read/written.
