| H A D | Makefile | 7ecc3e34 Wed Feb 23 04:35:03 CST 2022 Harsha <harsha.harsha@xilinx.com> crypto: xilinx - Add Xilinx SHA3 driver
This patch adds SHA3 driver support for the Xilinx ZynqMP SoC.
Xilinx ZynqMP SoC has SHA3 engine used for secure hash calculation.
The flow is
SHA3 request from Userspace -> SHA3 driver-> ZynqMp driver-> Firmware ->
SHA3 HW Engine
SHA3 HW engine in Xilinx ZynqMP SoC, does not support parallel processing
of 2 hash requests.
Therefore, software fallback is being used for init, update, final,
export and import in the ZynqMP SHA driver
For digest, the calculation of SHA3 hash is done by the hardened
SHA3 accelerator in Xilinx ZynqMP SoC.
