+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_DELAY_STR
+       string "Delay autobooting via specific input key / string"
+       depends on AUTOBOOT_KEYED
+       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
+       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
+       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.
