        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.

          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").

          Interface) is used mostly on x86 for providing information to the
          Operating System about devices in the system. The tables are set up
          by the firmware, typically U-Boot but possibly an earlier firmware
          module, if U-Boot is chain-loaded from something else. ACPI tables
          can also include code, to perform hardware-specific tasks required
          by the Operating Systems. This allows some amount of separation
          between the firmware and OS, and is particularly useful when you

config CMD_IO

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.

          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
