Subject[PATCH v6 0/5] Add Aspeed crypto driver for hardware acceleration
Date
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 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.
