2015-03-02imx6: Added DEK blob generator commandRaul Cardenas
Freescale's SEC block has built-in Data Encryption Key(DEK) Blob Protocol which provides a method for protecting a DEK for non-secure memory storage. SEC block protects data in a data structure called a Secret Key Blob, which provides both confidentiality and integrity protection. Every time the blob encapsulation is executed, a AES-256 key is randomly generated to encrypt the DEK. This key is encrypted with the OTP Secret key from SoC. The resulting blob consists of the encrypted AES-256 key, the encrypted DEK, and a 16-bit MAC. During decapsulation, the reverse process is performed to get back the original DEK. A caveat to the blob decapsulation process, is that the DEK is decrypted in secure-memory and can only be read by FSL SEC HW. The DEK is used to decrypt data during encrypted boot. Commands added -------------- dek_blob - encapsulating DEK as a cryptgraphic blob Commands Syntax --------------- dek_blob src dst len Encapsulate and create blob of a len-bits DEK at address src and store the result at address dst.

2015-01-23crypto/fsl: Add fixup for crypto nodeRuchika Gupta
Era property is added in the crypto node in device tree. Move the code to do so from arch/powerpc/mpc8xxx/fdt.c to drivers/sec/sec.c so that it can be used across arm and powerpc platforms having crypto node.

2014-10-16crypto/fsl: Add command for encapsulating/decapsulating blobsRuchika Gupta
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. Signed-off-by: Ruchika Gupta <ruchika.gupta@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
