4 bool "Support U-Boot commands"
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.
18 This option enables the "hush" shell (from Busybox) as command line
19 interpreter, thus enabling powerful command line syntax like
20 if...then...else...fi conditionals or `&&' and '||'
21 constructs ("shell scripts").
23 If disabled, you get the old, much simpler behaviour with a somewhat
24 smaller memory footprint.

33 menu "Autoboot options"
39 This enables the autoboot. See doc/README.autoboot for detail.
42 bool "Stop autobooting via specific input key / string"
45 This option enables stopping (aborting) of the automatic
46 boot feature only by issuing a specific input key or
47 string. If not enabled, any input key will abort the
48 U-Boot automatic booting process and bring the device
49 to the U-Boot prompt for user input.

52 string "Autoboot stop prompt"
53 depends on AUTOBOOT_KEYED
54 default "Autoboot in %d seconds\\n"
56 This string is displayed before the boot delay selected by
57 CONFIG_BOOTDELAY starts. If it is not defined there is no
58 output indicating that autoboot is in progress.
60 Note that this define is used as the (only) argument to a
61 printf() call, so it may contain '%' format specifications,
62 provided that it also includes, sepearated by commas exactly
63 like in a printf statement, the required arguments. It is
64 the responsibility of the user to select only such arguments
65 that are valid in the given context.

73 string "Delay autobooting via specific input key / string"
74 depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
76 This option delays the automatic boot feature by issuing
77 a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR
78 or the environment variable "bootdelaykey" is specified
79 and this string is received from console input before
80 autoboot starts booting, U-Boot gives a command prompt. The
81 U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is
82 used, otherwise it never times out.
84 config AUTOBOOT_STOP_STR
85 string "Stop autobooting via specific input key / string"
86 depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
88 This option enables stopping (aborting) of the automatic
89 boot feature only by issuing a specific input key or
90 string. If CONFIG_AUTOBOOT_STOP_STR or the environment
91 variable "bootstopkey" is specified and this string is
92 received from console input before autoboot starts booting,
93 U-Boot gives a command prompt. The U-Boot prompt never
94 times out, even if CONFIG_BOOT_RETRY_TIME is used.
96 config AUTOBOOT_KEYED_CTRLC
97 bool "Enable Ctrl-C autoboot interruption"
98 depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
101 This option allows for the boot sequence to be interrupted
102 by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".
103 Setting this variable provides an escape sequence from the
104 limited "password" strings.
106 config AUTOBOOT_STOP_STR_SHA256
107 string "Stop autobooting via SHA256 encrypted password"
108 depends on AUTOBOOT_KEYED && AUTOBOOT_ENCRYPTION
110 This option adds the feature to only stop the autobooting,
111 and therefore boot into the U-Boot prompt, when the input
112 string / password matches a values that is encypted via
113 a SHA256 hash and saved in the environment.

649 bool "ide - Support for IDE drivers"
652 Provides an 'ide' command which allows accessing the IDE drive,
653 reseting the IDE interface, printing the partition table and
654 geting device info. It also enables the 'diskboot' command which
655 permits booting from an IDE drive.
658 bool "io - Support for performing I/O accesses"
660 Provides an 'iod' command to display I/O space and an 'iow' command
661 to write values to the I/O space. This can be useful for manually
662 checking the state of devices during boot when debugging device
666 bool "iotrace - Support for tracing I/O activity"
668 Provides an 'iotrace' command which supports recording I/O reads and
669 writes in a trace buffer in memory . It also maintains a checksum
670 of the trace records (even if space is exhausted) so that the
671 sequence of I/O accesses can be verified.
673 When debugging drivers it is useful to see what I/O accesses were
674 done and in what order.
676 Even if the individual accesses are of little interest it can be
677 useful to verify that the access pattern is consistent each time
678 an operation is performed. In this case a checksum can be used to
679 characterise the operation of a driver. The checksum can be compared
680 across different runs of the operation to verify that the driver is
683 In particular, when performing major refactoring of the driver, where
684 the access pattern should not change, the checksum provides assurance
685 that the refactoring work has not broken the driver.
687 This works by sneaking into the io.h heder for an architecture and
688 redirecting I/O accesses through iotrace's tracing mechanism.
690 For now no commands are provided to examine the trace buffer. The
691 format is fairly simple, so 'md' is a reasonable substitute.
693 Note: The checksum feature is only useful for I/O regions where the
694 contents do not change outside of software control. Where this is not
695 suitable you can fall back to manually comparing the addresses. It
696 might be useful to enhance tracing to only checksum the accesses and
697 not the data read/written.

1152 cycles. SEC block protects data in a data structure called a Blob,
1153 which provides both confidentiality and integrity protection.
1155 Encapsulating data as a blob
1156 Each time that the Blob Protocol is used to protect data, a
1157 different randomly generated key is used to encrypt the data.
1158 This random key is itself encrypted using a key which is derived
1159 from SoC's non-volatile secret key and a 16 bit Key identifier.

1289 bool "fsuuid command"
1291 Enables fsuuid command for filesystem UUID.
1294 bool "jffs2 command"
1297 Enables commands to support the JFFS2 (Journalling Flash File System
1298 version 2) filesystem. This enables fsload, ls and fsinfo which
1299 provide the ability to load files, list directories and obtain
1300 filesystem information.
1303 bool "MTD partition support"
1305 MTD partition support
1307 config MTDIDS_DEFAULT
1308 string "Default MTD IDs"
1309 depends on CMD_MTDPARTS
1311 Defines a default MTD ID
1313 config MTDPARTS_DEFAULT
1314 string "Default MTD partition scheme"
1315 depends on CMD_MTDPARTS
1317 Defines a default MTD partitioning scheme in the Linux MTD command
1318 line partitions format
1320 config CMD_MTDPARTS_SPREAD
1321 bool "Padd partition size to take account of bad blocks"
1322 depends on CMD_MTDPARTS
1324 This enables the 'spread' sub-command of the mtdparts command.
1325 This command will modify the existing mtdparts variable by increasing
1326 the size of the partitions such that 1) each partition's net size is
1327 at least as large as the size specified in the mtdparts variable and
1328 2) each partition starts on a good block.
1331 bool "reiser - Access to reiserfs filesystems"
1333 This provides two commands which operate on a resierfs filesystem,
1334 commonly used some years ago:
1336 reiserls - list files
1337 reiserload - load a file
1340 bool "scsi - Access to SCSI devices"
1343 This provides a 'scsi' command which provides access to SCSI (Small
1344 Computer System Interface) devices. The command provides a way to
1345 scan the bus, reset the bus, read and write data and get information
1350 menu "Debug commands"

1391 default y if NAND_SUNXI
1393 UBI is a software layer above MTD layer which admits use of LVM-like
1394 logical volumes on top of MTD devices, hides some complexities of
1395 flash chips like wear and bad blocks and provides some other useful
1396 capabilities. Please, consult the MTD web site for more details
1397 (www.linux-mtd.infradead.org). Activate this option if you want
1398 to use U-Boot UBI commands.
