crypto: bfin_crc - CRC hardware driver for BF60x family processors.
The CRC peripheral is a hardware block used to compute the CRC of the block of data. This is based on a CRC32 engine which computes the CRC value of 32b data words presented to it. For data words of < 32b in size, this driver pack 0 automatically into 32b data units. This driver implements the async hash crypto framework API.
