From 8e8ec596e6c0144e2dd500a57ee23dde9684df46 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Sun, 13 Mar 2011 16:54:26 +0800 Subject: crypto: caam - Add support for the Freescale SEC4/CAAM The SEC4 supercedes the SEC2.x/3.x as Freescale's Integrated Security Engine. Its programming model is incompatible with all prior versions of the SEC (talitos). The SEC4 is also known as the Cryptographic Accelerator and Assurance Module (CAAM); this driver is named caam. This initial submission does not include support for Data Path mode operation - AEAD descriptors are submitted via the job ring interface, while the Queue Interface (QI) is enabled for use by others. Only AEAD algorithms are implemented at this time, for use with IPsec. Many thanks to the Freescale STC team for their contributions to this driver.
