* ata_pci_init_native_mode - Initialize native-mode driver
* @pdev: pci device to be initialized
* @port: array[2] of pointers to port info structures.
* @ports: bitmap of ports present
*
* Utility function which allocates and initializes an
* ata_probe_ent structure for a standard dual-port
* PIO-based IDE controller. The returned ata_probe_ent
* structure can be passed to ata_device_add(). The returned
* ata_probe_ent structure should then be freed with kfree().
*
* The caller need only pass the address of the primary port, the
* secondary will be deduced automatically. If the device has non
* standard secondary port mappings this function can be called twice,
* once for each interface.
