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
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".
126	  Setting this variable	provides an escape sequence from the

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

1812	bool "bedbug"
1813	help
1814	  The bedbug (emBEDded deBUGger) command provides debugging features
1815	  for some PowerPC processors. For details please see the
1816	  docuemntation in doc/README.beddbug
1817
1818config CMD_DIAG
1819	bool "diag - Board diagnostics"
1820	help
1821	  This command provides access to board diagnostic tests. These are
1822	  called Power-on Self Tests (POST). The command allows listing of
1823	  available tests and running either all the tests, or specific tests
1824	  identified by name.

1826config CMD_IRQ
1827	bool "irq - Show information about interrupts"
1828	depends on !ARM && !MIPS && !SH
1829	help
1830	  This enables two commands:
1831
1832	     interrupts - enable or disable interrupts
1833	     irqinfo - print device-specific interrupt information
1834
1835config CMD_KGDB
1836	bool "kgdb - Allow debugging of U-Boot with gdb"
1837	depends on PPC
1838	help
1839	  This enables a 'kgdb' command which allows gdb to connect to U-Boot
1840	  over a serial link for debugging purposes. This allows
1841	  single-stepping, inspecting variables, etc. This is supported only
1842	  on PowerPC at present.
1843
1844config CMD_LOG
1845	bool "log - Generation, control and access to logging"
1846	select LOG
1847	help
1848	  This provides access to logging features. It allows the output of
1849	  log data to be controlled to a limited extent (setting up the default
1850	  maximum log level for emitting of records). It also provides access
1851	  to a command used for testing the log system.
1852
1853config CMD_TRACE
1854	bool "trace - Support tracing of function calls and timing"
1855	help
1856	  Enables a command to control using of function tracing within
1857	  U-Boot. This allows recording of call traces including timing
1858	  information. The command can write data to memory for exporting
1859	  for analsys (e.g. using bootchart). See doc/README.trace for full
1860	  details.

1863	bool "avb - Android Verified Boot 2.0 operations"
1864	depends on AVB_VERIFY
1865	default n
1866	help
1867	  Enables a "avb" command to perform verification of partitions using
1868	  Android Verified Boot 2.0 functionality. It includes such subcommands:
1869	    avb init - initialize avb2 subsystem
1870	    avb read_rb - read rollback index
1871	    avb write_rb - write rollback index
1872	    avb is_unlocked - check device lock state
1873	    avb get_uuid - read and print uuid of a partition
1874	    avb read_part - read data from partition
1875	    avb read_part_hex - read data from partition and output to stdout
1876	    avb write_part - write data to partition
1877	    avb verify - run full verification chain

1884	help
1885	  UBI is a software layer above MTD layer which admits use of LVM-like
1886	  logical volumes on top of MTD devices, hides some complexities of
1887	  flash chips like wear and bad blocks and provides some other useful
1888	  capabilities. Please, consult the MTD web site for more details
1889	  (www.linux-mtd.infradead.org). Activate this option if you want
1890	  to use U-Boot UBI commands.
1891	  It is also strongly encouraged to also enable CONFIG_MTD to get full
1892	  partition support.
