From b51dbe90912a0ce0c78717d2a8374af80b18ed11 Mon Sep 17 00:00:00 2001 From: Fabien DESSENNE Date: Tue, 21 Mar 2017 16:13:28 +0100 Subject: crypto: stm32 - Support for STM32 CRC32 crypto module This module registers a CRC32 ("Ethernet") and a CRC32C (Castagnoli) algorithm that make use of the STMicroelectronics STM32 crypto hardware. Theses algorithms are compatible with the little-endian generic ones. Both algorithms use ~0 as default seed (key). With CRC32C the output is xored with ~0. Using TCRYPT CRC32C speed test, this shows up to 900% speedup compared to the crc32c-generic algorithm.
