Implement watchodg-aware variants of hash calculation functions: - crc32_wd() - md5_wd() - sha1_csum_wd() The above functions calculate the hash of the input buffer in chunks, triggering the watchdog after processing each chunk. The chunk size is given as a function call parameter. Signed-off-by: Bartlomiej Sieka <tur@semihalf.com>
