menu "Command line interface"
config CMDLINE
bool "Support U-Boot commands"
default y
help
Enable U-Boot's command-line functions. This provides a means
to enter commands into U-Boot for a wide variety of purposes. It
also allows scripts (containing commands) to be executed.
Various commands and command categorys can be indivdually enabled.
Depending on the number of commands enabled, this can add
substantially to the size of U-Boot.
config HUSH_PARSER
bool "Use hush shell"
depends on CMDLINE
help
This option enables the "hush" shell (from Busybox) as command line
interpreter, thus enabling powerful command line syntax like
if...then...else...fi conditionals or `&&' and '||'
constructs ("shell scripts").
If disabled, you get the old, much simpler behaviour with a somewhat
smaller memory footprint.
config SYS_PROMPT
string "Shell prompt"
default "=> "
help
This string is displayed in the command line to the left of the
cursor.
menu "Autoboot options"
config AUTOBOOT
bool "Autoboot"
default y
help
This enables the autoboot. See doc/README.autoboot for detail.
config AUTOBOOT_KEYED
bool "Stop autobooting via specific input key / string"
default n
help
This option enables stopping (aborting) of the automatic
boot feature only by issuing a specific input key or
string. If not enabled, any input key will abort the
U-Boot automatic booting process and bring the device
to the U-Boot prompt for user input.
config AUTOBOOT_PROMPT
string "Autoboot stop prompt"
depends on AUTOBOOT_KEYED
default "Autoboot in %d seconds\\n"
help
This string is displayed before the boot delay selected by
CONFIG_BOOTDELAY starts. If it is not defined there is no
output indicating that autoboot is in progress.
Note that this define is used as the (only) argument to a
printf() call, so it may contain '%' format specifications,
provided that it also includes, sepearated by commas exactly
like in a printf statement, the required arguments. It is
the responsibility of the user to select only such arguments
that are valid in the given context.
config AUTOBOOT_ENCRYPTION
bool "Enable encryption in autoboot stopping"
depends on AUTOBOOT_KEYED
default n
config AUTOBOOT_DELAY_STR
string "Delay autobooting via specific input key / string"
depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
help
This option delays the automatic boot feature by issuing
a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR
or the environment variable "bootdelaykey" is specified
and this string is received from console input before
autoboot starts booting, U-Boot gives a command prompt. The
U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is
used, otherwise it never times out.
config AUTOBOOT_STOP_STR
string "Stop autobooting via specific input key / string"
depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
help
This option enables stopping (aborting) of the automatic
boot feature only by issuing a specific input key or
string. If CONFIG_AUTOBOOT_STOP_STR or the environment
variable "bootstopkey" is specified and this string is
received from console input before autoboot starts booting,
U-Boot gives a command prompt. The U-Boot prompt never
times out, even if CONFIG_BOOT_RETRY_TIME is used.
config AUTOBOOT_KEYED_CTRLC
bool "Enable Ctrl-C autoboot interruption"
depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
default n
help
This option allows for the boot sequence to be interrupted
by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".
Setting this variable provides an escape sequence from the
limited "password" strings.
config AUTOBOOT_STOP_STR_SHA256
string "Stop autobooting via SHA256 encrypted password"
depends on AUTOBOOT_KEYED && AUTOBOOT_ENCRYPTION
help
This option adds the feature to only stop the autobooting,
and therefore boot into the U-Boot prompt, when the input
string / password matches a values that is encypted via
a SHA256 hash and saved in the environment.

that it can be used with the test/py testing framework. This is useful
for testing that EFI is working at a basic level, and for bringing
up EFI support on a new architecture.
No additional space will be required in the resulting U-Boot binary
when this option is enabled.

can be useful to see the state of driver model for debugging or
interest.
config CMD_DEMO

depends on DM
help
Provides a 'demo' command which can be used to play around with
driver model. To use this properly you will need to enable one or
both of the demo devices (DM_DEMO_SHAPE and DM_DEMO_SIMPLE).
Otherwise you will always get an empty list of devices. The demo
devices are defined in the sandbox device tree, so the easiest
option is to use sandbox and pass the -d point to sandbox's
u-boot.dtb file.
