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" select SYS_HUSH_PARSER 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_HUSH_PARSER bool help Backward compatibility. 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_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. endmenu comment "Commands" menu "Info commands" config CMD_BDI bool "bdinfo" default y help Print board info config CMD_CONSOLE bool "coninfo" default y help Print console devices and information. config CMD_CPU bool "cpu" help Print information about available CPUs.

This is not required for operation, but can be useful to see the state of driver model for debugging or interest. config CMD_DEMO bool "demo - Demonstration commands for driver model" 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. config CMD_LOADB bool "loadb" default y help Load a binary file over serial line. config CMD_LOADS bool "loads" default y help Load an S-Record file over serial line config CMD_FLASH bool "flinfo, erase, protect" default y help NOR flash support. flinfo - print FLASH memory information erase - FLASH memory protect - enable or disable FLASH write protection config CMD_ARMFLASH depends on FLASH_CFI_DRIVER bool "armflash" help ARM Ltd reference designs flash partition access config CMD_NAND bool "nand" help NAND support. config CMD_SF bool "sf" help SPI Flash support config CMD_SPI bool "sspi" help SPI utility command. config CMD_I2C bool "i2c" help I2C support. config CMD_USB bool "usb" help USB support. config CMD_FPGA bool "fpga" default y help FPGA support. config CMD_REMOTEPROC bool "remoteproc" depends on REMOTEPROC help Support for Remote Processor control config CMD_GPIO bool "gpio" help GPIO support. endmenu menu "Shell scripting commands" config CMD_ECHO bool "echo" default y help Echo args to console config CMD_ITEST bool "itest" default y help Return true/false on integer compare. config CMD_SOURCE bool "source" default y help Run script from memory config CMD_SETEXPR bool "setexpr" default y help Evaluate boolean and math expressions and store the result in an env variable.
