Subject: libata: spot bridge chips
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
If we have a PATA cable with a SATA drive on it then we've found a bridge and
we can flip the cable type. This fixes some cable detect problems with SATA
bridges on chipsets and misdetected cable types.
In theory cable detection and mode limiting is needed if you put a SATA/PATA
bridge on a 40 wire cable, but I see no way to deal with that other than to
point out its not a good idea anyway.
