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 AUTOBOOT_KEYED

	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.

	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.
