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
70	  string. If not enabled, any input key will abort the
71	  U-Boot automatic booting process and bring the device

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
115	  received from console input before autoboot starts booting,
116	  U-Boot gives a command prompt. The U-Boot prompt never

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

812
813config CMD_IOTRACE
814	bool "iotrace - Support for tracing I/O activity"
815	help
816	  Provides an 'iotrace' command which supports recording I/O reads and
817	  writes in a trace buffer in memory . It also maintains a checksum
818	  of the trace records (even if space is exhausted) so that the
819	  sequence of I/O accesses can be verified.
820
821	  When debugging drivers it is useful to see what I/O accesses were
822	  done and in what order.
823
824	  Even if the individual accesses are of little interest it can be
825	  useful to verify that the access pattern is consistent each time
826	  an operation is performed. In this case a checksum can be used to
827	  characterise the operation of a driver. The checksum can be compared
828	  across different runs of the operation to verify that the driver is
829	  working properly.
830
831	  In particular, when performing major refactoring of the driver, where
832	  the access pattern should not change, the checksum provides assurance
833	  that the refactoring work has not broken the driver.
834
835	  This works by sneaking into the io.h heder for an architecture and
836	  redirecting I/O accesses through iotrace's tracing mechanism.
837
838	  For now no commands are provided to examine the trace buffer. The
839	  format is fairly simple, so 'md' is a reasonable substitute.
840
841	  Note: The checksum feature is only useful for I/O regions where the
842	  contents do not change outside of software control. Where this is not
843	  suitable you can fall back to manually comparing the addresses. It
844	  might be useful to enhance tracing to only checksum the accesses and
845	  not the data read/written.
