Hello, This is an attempt to replace the mv_cesa driver by a new one to address some limitations of the existing driver. >From a performance and CPU load point of view the most important limitation is the lack of DMA support, thus preventing us from chaining crypto operations. I know we usually try to adapt existing drivers instead of replacing them by new ones, but after trying to refactor the mv_cesa driver I realized it would take longer than writing an new one from scratch. Here are the main features brought by this new driver: - support for armada SoCs (up to 38x) while keeping support for older ones (Orion and Kirkwood) - DMA mode to offload the CPU in case of intensive crypto usage - new algorithms: SHA256, DES and 3DES I'd like to thank Arnaud, who has carefully reviewed several iterations of this driver, helped me improved my implementation, provided support for several crypto algorithms, provided support for armada-370 and tested the driver on different platforms, hence the SoB and dual MODULE_AUTHOR in the driver code.
