Since this is a new, non-PATA, non-SATA controller/device setup, there are a few general questions, - what to do about cable detection? unless it matters, we could simply assume a fixed cable type, since its a virtual link. - what is the proper reset method? to kick a device (and controller) into action, we will COMRESET via the SATA phy, or at the very least SRST. - is set-xfer-mode properly emulated? normally we look at the ATA device's IDENTIFY DEVICE page, and choose a transfer xfer from that info.
