+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.

+	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

+	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

+config AUTOBOOT_STOP_STR

+	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.
