This patchset adds the implementation of SHA-3 algorithm
in software and it's based on original implementation
pushed in patch https://lwn.net/Articles/518415/ with
additional changes to match the padding rules specified
in SHA-3 specification.
This patchset also includes changes in tcrypt module to
add support for SHA-3 algorithms test and related test
vectors for basic testing.
Broadcom Secure Processing Unit-2(SPU-2) engine supports
offloading of SHA-3 operations in hardware, in order to
add SHA-3 support in SPU-2 driver we needed to have the
software implementation and test framework in place.
The patchset is based on v4.7-rc1 tag and its tested on
Broadcom NorthStar2 SoC.
The patch set can be fetched from iproc-sha3-v2 branch
of https://github.com/Broadcom/arm64-linux.git
Changes since v1:
- Renamed MODULE_ALIAS to MODULE_ALIAS_CRYPTO
- Added aliases for below cra_driver_name's
sha3-224-generic
sha3-256-generic
sha3-384-generic
sha3-512-generic
