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

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

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".

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