drivers/crypto/fsl: fix snooping for write transactions

2015-08-03T19:06:38Z

HW coherency won't work properly for CAAM write transactions if AWCACHE is left to default (POR) value - 4'b0001. It has to be programmed to 4'b0010. For platforms that have HW coherency support: -PPC-based: the update has no effect; CAAM coherency already works due to the IOMMU (PAMU) driver setting the correct memory coherency attributes -ARM-based: the update fixes cache coherency issues, since IOMMU (SMMU) driver is not programmed to behave similar to PAMU Fixes: b9eebfade974c ("fsl_sec: Add hardware accelerated SHA256 and SHA1") Signed-off-by: Horia Geantă Reviewed-by: Aneesh Bansal Reviewed-by: Mingkai Hu Acked-by: Ruchika Gupta Reviewed-by: York Sun

drivers/crypto/fsl: enable raw data instead of von Neumann data

2015-08-03T19:06:37Z

The sampling of the oscillator can be done in multiple modes for generating the entropy value. By default, this is set to von Neumann. This patch changes the sampling to raw data, since it has been discovered that the generated entropy has a better 'quality'.

drivers/crypto/fsl: disable RNG oscillator maximum frequency check

2015-08-03T19:06:37Z

The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

imx6: Added DEK blob generator command

2015-03-02T08:57:06Z

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.

crypto/fsl: Make function names consistent for blob encapsulation/decapsulation.

2015-02-25T21:19:48Z

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. Signed-off-by: Gaurav Rana Reviewed-by: Ruchika Gupta Reviewed-by: York Sun
