Aspeed ACRY engine is designed to accelerate the throughput of ECDSA/RSA signature and verification. These patches aim to add Aspeed ACRY RSA driver support. This driver also pass the run-time self tests that take place at algorithm registration on both big-endian/little-endian system in AST2600 evaluation board . 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 v4: - Remove GFP_DMA flag since it's unnecessary. Change since v3: - Revise aspeed,ast2600-ahbc.yaml dt-bindings description. Change since v2: - Fix format and uninitialized warning. - Revise binding description. Change since v1: - Fix dt-bindings description. - Refine the Makefile which has been addressed.
