    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").

    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

    	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.

    	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.

    	string "Stop autobooting via SHA256 encrypted password"
    	depends on AUTOBOOT_KEYED && AUTOBOOT_ENCRYPTION

    	  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.

    	  correctly. The tests cover initialisation, non-volatile RAM, extend,
    	  global lock and checking that timing is within expectations. The
    	  tests pass correctly on Infineon TPMs but may need to be adjusted
    	  for other devices.

    	  and talking to the I2C bus behind the EC (if there is one).

    	  UBI is a software layer above MTD layer which admits use of LVM-like
    	  logical volumes on top of MTD devices, hides some complexities of
    	  flash chips like wear and bad blocks and provides some other useful
    	  capabilities. Please, consult the MTD web site for more details
    	  (www.linux-mtd.infradead.org). Activate this option if you want
    	  to use U-Boot UBI commands.
