- * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original
- * SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511
- * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
- *
- * Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
- * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
- * can figure out that we have a more modern and more capable 5513 by looking
- * for the respective NorthBridge IDs.
- *
- * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
- * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
- * ID, while the now ATA-133 capable 5513 still has the same PCI ID.
- * Fortunately the 5513 can be 'unmasked' by fiddling with some config space
- * bits, changing its device id to the true one - 5517 for 961 and 5518 for
- * 962/963.
