Kconfig: Move autoboot options under boot options
At present the autoboot options are in cmd/Kconfig but they don't really
relate to commands. They relate to booting, so move this menu under the
boot menu.

+config AUTOBOOT
+ bool "Autoboot"
+ default y
+ help
+ This enables the autoboot. See doc/README.autoboot for detail.
+
+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
+ help
+ This option allows a string to be entered into U-Boot to stop the
+ autoboot. The string itself is hashed and compared against the hash
+ in the environment variable 'bootstopkeysha256'. If it matches then
+ boot stops and a command-line prompt is presented.
+
+ This provides a way to ship a secure production device which can also
+ be accessed at the U-Boot command line.
+
+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.
+
+config AUTOBOOT_USE_MENUKEY
+ bool "Allow a specify key to run a menu from the environment"
+ depends on !AUTOBOOT_KEYED
+ help
+ If a specific key is pressed to stop autoboot, then the commands in
+ the environment variable 'menucmd' are executed before boot starts.
+
+config AUTOBOOT_MENUKEY
+ int "ASCII value of boot key to show a menu"
+ default 0
+ depends on AUTOBOOT_USE_MENUKEY
+ help
+ If this key is pressed to stop autoboot, then the commands in the
+ environment variable 'menucmd' will be executed before boot starts.
+ For example, 33 means "!" in ASCII, so pressing ! at boot would take
+ this action.
+
+config AUTOBOOT_MENU_SHOW
+ bool "Show a menu on boot"
+ depends on CMD_BOOTMENU
+ help
+ This enables the boot menu, controlled by environment variables
+ defined by the board. The menu starts after running the 'preboot'
+ environmnent variable (if enabled) and before handling the boot delay.
+ See README.bootmenu for more details.
