Hi all, This series adds support for the Inside Secure SafeXcel EIP197 cryptographic engine which can be found on Marvell Armada 7k and 8k boards. A new cryptographic engine driver is added, as well as the relevant device tree definition for the Armada 7040 DB and 8040 DB boards.
This driver needs two firmwares to work correctly. These firmware are usually used for more advanced operations than the ones supported (as of now), but we still need them to pass the data to the internal cryptographic engine. This series was tested in various ways on both the Armada 7040 DB and the Armada 8040 DB: using the crypto framework self tests, using tcrypt and while performing various transfers with iperf on top of IPsec. This series is based on top of v4.11-rc1, and is available on a branch (which also contains the PPv2 support for 7k/8k, to ease the process of testing IPsec): https://github.com/atenart/linux v4.11-rc1/7k8k-crypto I can rebase if needed. Patches adding device tree nodes and modifying the arm64 defconfig have been applied to the mvebu tree already. I'd like to thank Ofer Heifetz and Igal Liberman who helped me to do this driver by adding functionalities, optimizing functions and testing (a lot). Thanks, Antoine Since v1: - Fixed two compilation issues reported by Kbuild. - Removed all dma_to_phys() calls and used the dma addresses instead. - Added a call to dma_set_mask_and_coherent() before calling any DMA API helper. - Removed some DMA free functions to avoid double-freeing. - Do not rely on sg_nents_for_len() to get the number of sg anymore. - Added a dedicated kmalloc'ed cache to use for dma_map_single().
