The function sha256_csum_wd is defined in lib/sha256.c and in lib/mbedtls/sha256.c. To avoid duplicating this function (and future function), we move this function to the file lib/sha256_common.c Reviewed-by: Raymond Mao <raymond.mao@linaro.org> Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com>
