menu "Command line interface"

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").

	  If disabled, you get the old, much simpler behaviour with a somewhat
	  smaller memory footprint.

	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
	default n

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 CMD_IO
	bool "io - Support for performing I/O accesses"
	help
	  Provides an 'iod' command to display I/O space and an 'iow' command
	  to write values to the I/O space. This can be useful for manually
	  checking the state of devices during boot when debugging device
	  drivers, etc.

config CMD_IOTRACE
	bool "iotrace - Support for tracing I/O activity"
	help
	  Provides an 'iotrace' command which supports recording I/O reads and
	  writes in a trace buffer in memory . It also maintains a checksum
	  of the trace records (even if space is exhausted) so that the
	  sequence of I/O accesses can be verified.

	  When debugging drivers it is useful to see what I/O accesses were
	  done and in what order.

	  Even if the individual accesses are of little interest it can be
	  useful to verify that the access pattern is consistent each time
	  an operation is performed. In this case a checksum can be used to
	  characterise the operation of a driver. The checksum can be compared
	  across different runs of the operation to verify that the driver is
	  working properly.

	  In particular, when performing major refactoring of the driver, where
	  the access pattern should not change, the checksum provides assurance
	  that the refactoring work has not broken the driver.

	  This works by sneaking into the io.h heder for an architecture and
	  redirecting I/O accesses through iotrace's tracing mechanism.

	  For now no commands are provided to examine the trace buffer. The
	  format is fairly simple, so 'md' is a reasonable substitute.

	  Note: The checksum feature is only useful for I/O regions where the
	  contents do not change outside of software control. Where this is not
	  suitable you can fall back to manually comparing the addresses. It
	  might be useful to enhance tracing to only checksum the accesses and
	  not the data read/written.

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
