1 menu "Command line interface"
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.
30 This string is displayed in the command line to the left of the
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.
51 config AUTOBOOT_PROMPT
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.
67 config AUTOBOOT_ENCRYPTION
68 bool "Enable encryption in autoboot stopping"
69 depends on AUTOBOOT_KEYED
72 config AUTOBOOT_DELAY_STR
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.

326 bool "dm - Access to driver model information"
330 Provides access to driver model data structures and information,
331 such as a list of devices, list of uclasses and the state of each
332 device (e.g. activated). This is not required for operation, but
333 can be useful to see the state of driver model for debugging or
337 bool "demo - Demonstration commands for driver model"
340 Provides a 'demo' command which can be used to play around with
341 driver model. To use this properly you will need to enable one or
342 both of the demo devices (DM_DEMO_SHAPE and DM_DEMO_SIMPLE).
343 Otherwise you will always get an empty list of devices. The demo
344 devices are defined in the sandbox device tree, so the easiest
345 option is to use sandbox and pass the -d point to sandbox's

554 depends on BLOCK_CACHE
555 default y if BLOCK_CACHE
557 Enable the blkcache command, which can be used to control the
558 operation of the cache functions.
559 This is most useful when fine-tuning the operation of the cache
560 during development, but also allows the cache to be disabled when
561 it might hurt performance (e.g. when using the ums command).

664 command requires a suitable TPM on your board and the correct driver
668 bool "Enable the 'tpm test' command"
671 This provides a a series of tests to confirm that the TPM is working
672 correctly. The tests cover initialisation, non-volatile RAM, extend,
673 global lock and checking that timing is within expectations. The
