+       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_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

+         provided that it also includes, sepearated by commas exactly
+         like in a printf statement, the required arguments. It is

+       help
+         This option delays the automatic boot feature by issuing

+         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

+         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

+         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

+         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.
