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.

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

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

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

121	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
122	default n

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

742	help
743	  Provides an 'iotrace' command which supports recording I/O reads and
744	  writes in a trace buffer in memory . It also maintains a checksum
745	  of the trace records (even if space is exhausted) so that the
746	  sequence of I/O accesses can be verified.
747
748	  When debugging drivers it is useful to see what I/O accesses were
749	  done and in what order.
750
751	  Even if the individual accesses are of little interest it can be
752	  useful to verify that the access pattern is consistent each time
753	  an operation is performed. In this case a checksum can be used to
754	  characterise the operation of a driver. The checksum can be compared
755	  across different runs of the operation to verify that the driver is
756	  working properly.
757
758	  In particular, when performing major refactoring of the driver, where
759	  the access pattern should not change, the checksum provides assurance
760	  that the refactoring work has not broken the driver.
761
762	  This works by sneaking into the io.h heder for an architecture and
763	  redirecting I/O accesses through iotrace's tracing mechanism.
764
765	  For now no commands are provided to examine the trace buffer. The
766	  format is fairly simple, so 'md' is a reasonable substitute.
767
768	  Note: The checksum feature is only useful for I/O regions where the
769	  contents do not change outside of software control. Where this is not
770	  suitable you can fall back to manually comparing the addresses. It
771	  might be useful to enhance tracing to only checksum the accesses and
772	  not the data read/written.
