Planning on writing this as I also work on a variety of CDI patches discussed elsewhere.

SATA is effectively SCSI transmitted to a device via a HCI (usually AHCI) in a command block (also known as a FIS). Got a better understanding of this concept after working with the USB Mass Storage class.
Depends on CDI having decent SCSI support, and also inter-driver communication. Will send Kevin Wolf an update on this one.

AlexExtreme has now written a SATA driver (or at least an AHCI driver) - might be able to refer to that.

A few things missing in CDI yet - the concept of a "bus" driver for AHCI for example. I might talk to Kevin Wolf about this soon - will depend on inter-driver communication.
As for SATA itself it is essentially SCSI commands transmitted via a specific protocol, over the bus (AHCI or other such interfaces).
