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 v2:
- Fix format and uninitialized warning.
- Revise binding description.
Change since v1:
- Fix dt-bindings description.
- Refine the Makefile which has been addressed.
