	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

	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 '||'

	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

	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,

	  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

	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 CMD_AES
	bool "Enable the 'aes' command"
	select AES
	help
	  This provides a means to encrypt and decrypt data using the AES
	  (Advanced Encryption Standard). This algorithm uses a symetric key
	  and is widely used as a streaming cipher. Different key lengths are
	  supported by the algorithm but this command only supports 128 bits
	  at present.

config CMD_BLOB
	bool "Enable the 'blob' command"
	help
	  This is used with the Freescale secure boot mechanism.

	  Freescale's SEC block has built-in Blob Protocol which provides
	  a method for protecting user-defined data across system power
	  cycles. SEC block protects data in a data structure called a Blob,
	  which provides both confidentiality and integrity protection.

	  Encapsulating data as a blob
	  Each time that the Blob Protocol is used to protect data, a
	  different randomly generated key is used to encrypt the data.
	  This random key is itself encrypted using a key which is derived
	  from SoC's non-volatile secret key and a 16 bit Key identifier.
	  The resulting encrypted key along with encrypted data is called a
	  blob. The non-volatile secure key is available for use only during
	  secure boot.

	  During decapsulation, the reverse process is performed to get back
	  the original data.

	  Sub-commands:
            blob enc - encapsulating data as a cryptgraphic blob
	    blob dec - decapsulating cryptgraphic blob to get the data

	  Syntax:

	  blob enc src dst len km

	  Encapsulate and create blob of data $len bytes long
	  at address $src and store the result at address $dst.
	  $km is the 16 byte key modifier is also required for
	  generation/use as key for cryptographic operation. Key
	  modifier should be 16 byte long.

	  blob dec src dst len km

	  Decapsulate the  blob of data at address $src and
	  store result of $len byte at addr $dst.
	  $km is the 16 byte key modifier is also required for
	  generation/use as key for cryptographic operation. Key
	  modifier should be 16 byte long.

config CMD_TPM
	bool "Enable the 'tpm' command"
	depends on TPM
	help
	  This provides a means to talk to a TPM from the command line. A wide
	  range of commands if provided - see 'tpm help' for details. The
	  command requires a suitable TPM on your board and the correct driver
	  must be enabled.

config CMD_TPM_TEST
	bool "Enable the 'tpm test' command"
	depends on CMD_TPM
	help
	  This provides a a series of tests to confirm that the TPM is working
	  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.

	  Define this to enable support for reading from a Coreboot

	  on systems that use coreboot as the first boot-loader and then load
	  U-Boot to actually boot the Operating System. Available commands are

	  compressed. Two commands are provided:

	     cramfsls   - lists files in a cramfs image
	     cramfsload - loads a file from a cramfs image
