29 | /* | |
30 | * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original | |
31 | * SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511 | |
32 | * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip. | |
33 | * | |
34 | * Later SiS chipsets integrated the 5513 functionality into the NorthBridge, | |
35 | * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We | |
36 | * can figure out that we have a more modern and more capable 5513 by looking | |
37 | * for the respective NorthBridge IDs. | |
38 | * | |
39 | * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513 | |
40 | * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI | |
41 | * ID, while the now ATA-133 capable 5513 still has the same PCI ID. | |
42 | * Fortunately the 5513 can be 'unmasked' by fiddling with some config space | |
43 | * bits, changing its device id to the true one - 5517 for 961 and 5518 for | |
44 | * 962/963. | |
