2015-02-25crypto/fsl: Make function names consistent for blob encapsulation/decapsulation.gaurav rana
This patch does the following: 1. The function names for encapsulation and decapsulation were inconsitent in freescale's implementation and cmd_blob file. This patch corrects the issues. 2. The function protopye is also modified to change the length parameter from u8 to u32 to allow encapsulation and decapsulation of larger images. 3. Modified the description of km paramter in the command usage for better readability.

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.

2014-12-15crypto/fsl: Fix RNG instantiation failure.gaurav rana
Corrected the order of arguments in memset in run_descriptor function. Wrong order of argumnets led to improper initialization of members of struct type result. This resulted in RNG instantiation error. Signed-off-by: Gaurav Rana <gaurav.rana@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
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>

2014-06-19includes: move openssl headers to include/u-bootJeroen Hofstee
commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-03-28drivers: crypto: ace_sha: add implementation of hardware based lib randPrzemyslaw Marczak
This patch adds implementation of rand library based on hardware random number generator of security subsystem in Exynos SOC. This library includes: - srand() - used for seed hardware block - rand() - returns random number - rand_r() - the same as above with given seed which depends on CONFIG_EXYNOS_ACE_SHA and CONFIG_LIB_HW_RAND.
