At present the SATA command code includes both the command-processing code and the core SATA functions and data structures. Separate the latter into its own file, adding functions as needed to avoid the command code accessing data structures directly. With this commit: - All CONFIG option are referenced from the non-command code - The concept of a 'current SATA device' is confined to the command code This will make it easier to convert this code to driver model.
