crypto: dcp - Added support for Freescale's DCP co-processor

2013-05-28T07:43:03Z

This patch enables the DCP crypto functionality on imx28. Currently, only aes-128-cbc is supported. Moreover, the dcpboot misc-device, which is used by Freescale's SDK tools and uses a non-software-readable OTP-key, is added. Changes of v2: - ring buffer for hardware-descriptors - use of ablkcipher walk - OTP key encryption/decryption via misc-device (compatible to Freescale-SDK) - overall cleanup The DCP is also capable of sha1/sha256 but I won't be able to add that anytime soon. Tested with built-in runtime-self-test, tcrypt and openssl via cryptodev 1.6 on imx28-evk and a custom built imx28-board. Signed-off-by: Tobias Rauter Signed-off-by: Herbert Xu
