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".
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.

1803config CMD_BEDBUG
1804	bool "bedbug"
1805	help
1806	  The bedbug (emBEDded deBUGger) command provides debugging features
1807	  for some PowerPC processors. For details please see the
1808	  docuemntation in doc/README.beddbug
1809
1810config CMD_DIAG
1811	bool "diag - Board diagnostics"
1812	help
1813	  This command provides access to board diagnostic tests. These are
1814	  called Power-on Self Tests (POST). The command allows listing of
1815	  available tests and running either all the tests, or specific tests
1816	  identified by name.
1817
1818config CMD_IRQ
1819	bool "irq - Show information about interrupts"
1820	depends on !ARM && !MIPS && !SH
1821	help
1822	  This enables two commands:
1823
1824	     interrupts - enable or disable interrupts
1825	     irqinfo - print device-specific interrupt information
1826
1827config CMD_KGDB
1828	bool "kgdb - Allow debugging of U-Boot with gdb"
1829	depends on PPC
1830	help
1831	  This enables a 'kgdb' command which allows gdb to connect to U-Boot
1832	  over a serial link for debugging purposes. This allows
1833	  single-stepping, inspecting variables, etc. This is supported only
1834	  on PowerPC at present.
1835
1836config CMD_LOG
1837	bool "log - Generation, control and access to logging"
1838	select LOG
1839	help
1840	  This provides access to logging features. It allows the output of
1841	  log data to be controlled to a limited extent (setting up the default
1842	  maximum log level for emitting of records). It also provides access
1843	  to a command used for testing the log system.
1844
1845config CMD_TRACE
1846	bool "trace - Support tracing of function calls and timing"
1847	help
1848	  Enables a command to control using of function tracing within
1849	  U-Boot. This allows recording of call traces including timing
1850	  information. The command can write data to memory for exporting
1851	  for analsys (e.g. using bootchart). See doc/README.trace for full
1852	  details.
1853
1854config CMD_AVB
1855	bool "avb - Android Verified Boot 2.0 operations"
1856	depends on AVB_VERIFY
1857	default n
1858	help
1859	  Enables a "avb" command to perform verification of partitions using
1860	  Android Verified Boot 2.0 functionality. It includes such subcommands:
1861	    avb init - initialize avb2 subsystem
1862	    avb read_rb - read rollback index
1863	    avb write_rb - write rollback index
1864	    avb is_unlocked - check device lock state
1865	    avb get_uuid - read and print uuid of a partition
1866	    avb read_part - read data from partition
1867	    avb read_part_hex - read data from partition and output to stdout
1868	    avb write_part - write data to partition
1869	    avb verify - run full verification chain

1873	tristate "Enable UBI - Unsorted block images commands"
1874	select CRC32
1875	select MTD_UBI
1876	help
1877	  UBI is a software layer above MTD layer which admits use of LVM-like
1878	  logical volumes on top of MTD devices, hides some complexities of
1879	  flash chips like wear and bad blocks and provides some other useful
1880	  capabilities. Please, consult the MTD web site for more details
1881	  (www.linux-mtd.infradead.org). Activate this option if you want
1882	  to use U-Boot UBI commands.
1883	  It is also strongly encouraged to also enable CONFIG_MTD to get full
1884	  partition support.
1885
1886config CMD_UBIFS
1887	tristate "Enable UBIFS - Unsorted block images filesystem commands"
1888	depends on CMD_UBI
1889	default y if CMD_UBI
1890	select CRC32
1891	select LZO
1892	help
1893	  UBIFS is a file system for flash devices which works on top of UBI.
