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

20	  if...then...else...fi conditionals or `&&' and '||'

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

100	  a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR
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".

795
796config CMD_IOTRACE
797	bool "iotrace - Support for tracing I/O activity"
798	help
799	  Provides an 'iotrace' command which supports recording I/O reads and
800	  writes in a trace buffer in memory . It also maintains a checksum
801	  of the trace records (even if space is exhausted) so that the
802	  sequence of I/O accesses can be verified.
803
804	  When debugging drivers it is useful to see what I/O accesses were
805	  done and in what order.
806
807	  Even if the individual accesses are of little interest it can be
808	  useful to verify that the access pattern is consistent each time
809	  an operation is performed. In this case a checksum can be used to
810	  characterise the operation of a driver. The checksum can be compared
811	  across different runs of the operation to verify that the driver is
812	  working properly.
813
814	  In particular, when performing major refactoring of the driver, where
815	  the access pattern should not change, the checksum provides assurance
816	  that the refactoring work has not broken the driver.
817
818	  This works by sneaking into the io.h heder for an architecture and
819	  redirecting I/O accesses through iotrace's tracing mechanism.
820
821	  For now no commands are provided to examine the trace buffer. The
822	  format is fairly simple, so 'md' is a reasonable substitute.
823
824	  Note: The checksum feature is only useful for I/O regions where the
825	  contents do not change outside of software control. Where this is not
826	  suitable you can fall back to manually comparing the addresses. It
827	  might be useful to enhance tracing to only checksum the accesses and
828	  not the data read/written.
