This patch is base on reference(1) algorithm with some changes. - Redefine the block number to two. - That's due to only two pipe-line can be used in CRC32 calculate. - Redefine the block size: - The block size of CRC is 1536B and PMULL is 512B - Interleave CRC and PMULL instructions. The optimization parameters are calculated base on reference(2) References: - https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/fast-crc-computation-generic-polynomials-pclmulqdq-paper.pdf - https://developer.arm.com/docs/swog309707/a Change-Id: I1c9e593d59b521f56e4b3c807b396c083c181636 Signed-off-by: Jerry Yu <jerry.h.yu@arm.com>
