Hi Simon,

I have defined the functions for hardware acceleration which are already present in hash.c for Freescale platforms.

In hash.c static struct hash_algo hash_algo[] = { /* * CONFIG_SHA_HW_ACCEL is defined if hardware acceleration is * available. */ #ifdef CONFIG_SHA_HW_ACCEL { "sha1", SHA1_SUM_LEN, hw_sha1, CHUNKSZ_SHA1, }, { "sha256", SHA256_SUM_LEN, hw_sha256, CHUNKSZ_SHA256, }, #endif /*

In the patch below, I have added defined the above functions for Freescale platforms.

+void hw_sha256(const unsigned char *pbuf, unsigned int buf_len, + unsigned char *pout, unsigned int chunk_size) +{ + if (caam_hash(pbuf, buf_len, pout, SHA256)) + printf("CAAM was not setup properly or it is faulty\n"); +} + +void hw_sha1(const unsigned char *pbuf, unsigned int buf_len, + unsigned char *pout, unsigned int chunk_size) +{ + if (caam_hash(pbuf, buf_len, pout, SHA1)) + printf("CAAM was not setup properly or it is faulty\n"); +}

Regards, Ruchika

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.

Changes from v2: CAAM init was earlier enabled by default for all platforms with SEC > 4. Restricting it to platforms which want to enable CAAM

Changes from v1: Added a common function run_descriptor_jr to avoid repetition of common code

Are you able to plumb this into hash.c? See hash_algo[].
