Subject: [PATCH v3 0/5] Add Aspeed crypto driver for hardware acceleration
Date: Tue, 21 Jun 2022 14:37:47 +0800	[thread overview]
Message-ID: <20220621063752.1005781-1-neal_liu@aspeedtech.com> (raw)

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.

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 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.
