fsl_sec: Add hardware accelerated SHA256 and SHA1 SHA-256 and SHA-1 accelerated using SEC hardware in Freescale SoC's The driver for SEC (CAAM) IP is based on linux drivers/crypto/caam. The platforms needto add the MACRO CONFIG_FSL_CAAM inorder to enable initialization of this hardware IP.

crypto/fsl: Add command for encapsulating/decapsulating blobs 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. Commands added -------------- blob enc - encapsulating data as a cryptgraphic blob blob dec - decapsulating cryptgraphic blob to get the data Commands 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 store result of $len byte at addr $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.
