Aspeed Hash and Crypto Engine (HACE) is designed to accelerate the throughput of hash data digest, encryption and decryption. These patches aim to add Aspeed hash & crypto driver support. The hash & crypto driver also pass the run-time self tests that take place at algorithm registration. The patch series are tested on both AST2500 & AST2600 evaluation boards. Tested-by below configs: - CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set - CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y - CONFIG_DMA_API_DEBUG=y - CONFIG_DMA_API_DEBUG_SG=y - CONFIG_CPU_BIG_ENDIAN=y Change since v7: - Define debug Kconfigs. - Simplify assign iv/ivsize. - Simplify cra_init() for hmac related init. Change since v6: - Refine debug print. - Change aspeed_sg_list struct memeber's type to __le32. Change since v5: - Re-define HACE clock define to fix breaking ABI. Change since v4: - Add AST2500 clock definition & dts node. - Add software fallback for handling corner cases. - Fix copy wrong key length. Change since v3: - Use dmam_alloc_coherent() instead to manage dma_alloc_coherent(). - Add more error handler of dma_prepare() & crypto_engine_start(). Change since v2: - Fix endianness issue. Tested on both little endian & big endian system. - Use common crypto hardware engine for enqueue & dequeue requests. - Use pre-defined IVs for SHA-family. - Revise error handler flow. - Fix sorts of coding style problems. Change since v1: - Add more error handlers, including DMA memory allocate/free, DMA map/unmap, clock enable/disable, etc. - Fix check dma_map error for config DMA_API_DEBUG. - Fix dt-binding doc & dts node naming.
