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

81	  output indicating that autoboot is in progress.
82
83	  Note that this define is used as the (only) argument to a

113	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
114	  variable "bootstopkey" is specified and this string is

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

791
792config CMD_IOTRACE

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

1820	bool "diag - Board diagnostics"
1821	help
1822	  This command provides access to board diagnostic tests. These are
1823	  called Power-on Self Tests (POST). The command allows listing of
1824	  available tests and running either all the tests, or specific tests
1825	  identified by name.

1827config CMD_IRQ
1828	bool "irq - Show information about interrupts"
1829	depends on !ARM && !MIPS && !SH
1830	help
1831	  This enables two commands:
1832
1833	     interrupts - enable or disable interrupts
1834	     irqinfo - print device-specific interrupt information

1836config CMD_KGDB
1837	bool "kgdb - Allow debugging of U-Boot with gdb"
1838	depends on PPC
1839	help
1840	  This enables a 'kgdb' command which allows gdb to connect to U-Boot
1841	  over a serial link for debugging purposes. This allows
1842	  single-stepping, inspecting variables, etc. This is supported only
1843	  on PowerPC at present.

1845config CMD_LOG
1846	bool "log - Generation, control and access to logging"
1847	select LOG
1848	help
1849	  This provides access to logging features. It allows the output of
1850	  log data to be controlled to a limited extent (setting up the default
1851	  maximum log level for emitting of records). It also provides access
1852	  to a command used for testing the log system.

1855	bool "trace - Support tracing of function calls and timing"
1856	help
1857	  Enables a command to control using of function tracing within
1858	  U-Boot. This allows recording of call traces including timing
1859	  information. The command can write data to memory for exporting
1860	  for analsys (e.g. using bootchart). See doc/README.trace for full
1861	  details.

1869	  Android Verified Boot 2.0 functionality. It includes such subcommands:
1870	    avb init - initialize avb2 subsystem
1871	    avb read_rb - read rollback index
1872	    avb write_rb - write rollback index
1873	    avb is_unlocked - check device lock state
1874	    avb get_uuid - read and print uuid of a partition
1875	    avb read_part - read data from partition
1876	    avb read_part_hex - read data from partition and output to stdout
1877	    avb write_part - write data to partition
1878	    avb verify - run full verification chain

1886	  UBI is a software layer above MTD layer which admits use of LVM-like
1887	  logical volumes on top of MTD devices, hides some complexities of
1888	  flash chips like wear and bad blocks and provides some other useful
1889	  capabilities. Please, consult the MTD web site for more details
1890	  (www.linux-mtd.infradead.org). Activate this option if you want
1891	  to use U-Boot UBI commands.
1892	  It is also strongly encouraged to also enable CONFIG_MTD to get full
1893	  partition support.
