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. Signed-off-by:Fabien Dessenne <fabien.dessenne@st.com> Signed-off-by:
