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

This provides a way to obtain information about a BMP-format iamge

|
|
file format defined by Microsoft which supports images of various
|
|
depths, formats and compression methods. Headers on the file
|

determine the formats used. This command can be used by first loading

the image into RAM, then using this command to look at it or display

it.

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
