402 In case of an ECC error this function is called for error detection
403 and correction. Return 1 respectively 2 in case the error can be
404 corrected. If the error is not correctable return -1. If your
406 software generator then use the correction function provided by
412 Many hardware ECC implementations provide Reed-Solomon codes and
413 calculate an error syndrome on read. The syndrome must be converted to a
414 standard Reed-Solomon syndrome before calling the error correction code
