5	default y
6	help
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
12	  substantially to the size of U-Boot.

19	  interpreter, thus enabling powerful command line syntax like
20	  if...then...else...fi conditionals or `&&' and '||'
21	  constructs ("shell scripts").

66	default n
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
72	  to the U-Boot prompt for user input.

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
86	  like in a printf statement, the required arguments. It is

98	help
99	  This option delays the automatic boot feature by issuing
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
104	  U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is

110	help
111	  This option enables stopping (aborting) of the automatic
112	  boot feature only by issuing a specific input key or
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
117	  times out, even if CONFIG_BOOT_RETRY_TIME is used.

121	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
122	default n
123	help
124	  This option allows for the boot sequence to be interrupted
125	  by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".
126	  Setting this variable	provides an escape sequence from the

135	  string / password matches a values that is encypted via
136	  a SHA256 hash and saved in the environment.

765	help
766	  Provides an 'iotrace' command which supports recording I/O reads and
767	  writes in a trace buffer in memory . It also maintains a checksum
768	  of the trace records (even if space is exhausted) so that the
769	  sequence of I/O accesses can be verified.
770
771	  When debugging drivers it is useful to see what I/O accesses were
772	  done and in what order.
773
774	  Even if the individual accesses are of little interest it can be
775	  useful to verify that the access pattern is consistent each time
776	  an operation is performed. In this case a checksum can be used to
777	  characterise the operation of a driver. The checksum can be compared
778	  across different runs of the operation to verify that the driver is
779	  working properly.
780
781	  In particular, when performing major refactoring of the driver, where
782	  the access pattern should not change, the checksum provides assurance
783	  that the refactoring work has not broken the driver.
784
785	  This works by sneaking into the io.h heder for an architecture and
786	  redirecting I/O accesses through iotrace's tracing mechanism.
787
788	  For now no commands are provided to examine the trace buffer. The
789	  format is fairly simple, so 'md' is a reasonable substitute.
790
791	  Note: The checksum feature is only useful for I/O regions where the
792	  contents do not change outside of software control. Where this is not
793	  suitable you can fall back to manually comparing the addresses. It
794	  might be useful to enhance tracing to only checksum the accesses and
795	  not the data read/written.
