[PATCH V3 0/4] crypto: Add Xilinx ZynqMP SHA3 driver support

From: Harsha
Date: Wed Feb 23 2022 - 05:36:15 EST


This patch set does the following:
- Updates the Makefile for xilinx subdirectory
- Adds communication layer support for sha_hash in zynqmp.c
- Adds Xilinx ZynqMP driver for SHA3 Algorithm
- Updates the list of MAINTAINERS

Following tests have been done for the driver:
- Enabled kernel self tests and extra run-time crypto self tests
- Tested SHA hash computation for different sizes of data using
userspace application
- Tested SHA hash computation using multiple updates of data using
userspace application
- Tested parallel hash computation
- Tested using the tcrypt module

V3 changes:
Added details of tests in cover letter
Added SOB for previous poster of RFC patch
Removed module_platform_driver in 3/4
Used memzero_explicit instead of memset in 3/4

V2 changes:
- Removed dependency on COMPILE_TEST in 3/4
- Rebased this patchset on latest Cryptodev-2.6 tree which fixed
below kernel robot warning

|
- Included linux/cacheflush.h instead of asm/cacheflush.h in 3/4

V1 changes:
- Converted RFC patch to PATCH
- Updated zynqmp-sha driver so that it can be self discovered
- Removed patch 3/6 and 4/6 as they added support for device tree
- Substituted hw with hardware in drivers/crypto/Kconfig
