From 4a5dc51e93e80463010ab4d8d00fc9cb6bc936fa Mon Sep 17 00:00:00 2001 From: Marcin Nowakowski Date: Fri, 9 Feb 2018 22:11:06 +0000 Subject: MIPS: crypto: Add crc32 and crc32c hw accelerated module This module registers crc32 and crc32c algorithms that use the optional CRC32[bhwd] and CRC32C[bhwd] instructions in MIPSr6 cores.
