+ This is used with the Freescale secure boot mechanism.

+ Freescale's SEC block has built-in Blob Protocol which provides

+ 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.
