menuconfig CMDLINE
bool "Command line interface"
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"
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.

the environment.

config CMD_ACPI
bool "acpi"
depends on ACPI
default y
help
List and dump ACPI tables. ACPI (Advanced Configuration and Power
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
want to make hardware changes without the OS needing to be adjusted.

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.

Create virtual block devices that are backed by various sources,

subsystem.
Example use-cases:
- Treat a region of RAM as a block device, i.e. a RAM disk. This let's
you extract files from filesystem images stored in RAM (perhaps as a
result of a TFTP transfer).
- Create a virtual partition on an existing device. This let's you
access filesystems that aren't stored at an exact partition

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
