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

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

80	  CONFIG_BOOTDELAY starts. If it is not defined	there is no
81	  output indicating that autoboot is in progress.
82
83	  Note that this define is used as the (only) argument to a
84	  printf() call, so it may contain '%' format specifications,
85	  provided that it also includes, sepearated by commas exactly

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

113	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
114	  variable "bootstopkey" is specified and this string is

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

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

1814	  It is strongly encouraged to avoid using this command
1815	  anymore along with 'sf', 'nand', 'onenand'. One can still
1816	  declare the partitions in the mtdparts environment variable
1817	  but better use the MTD stack and the 'mtd' command instead.
