From: Bartlomiej Zolnierkiewicz @ 2008-06-22 19:36 UTC (permalink / raw)
To: linux-ide; +Cc: Bartlomiej Zolnierkiewicz, linux-kernel
* Add struct ide_tp_ops for transport methods.
* Add 'const struct ide_tp_ops *tp_ops' to struct ide_port_info
and ide_hwif_t.
* Set the default hwif->tp_ops in ide_init_port_data().
* Set host driver specific hwif->tp_ops in ide_init_port().
* Export ide_exec_command(), ide_read_status(), ide_read_altstatus(),
ide_read_sff_dma_status(), ide_set_irq(), ide_tf_{load,read}()
and ata_{in,out}put_data().
* Convert host drivers and core code to use struct ide_tp_ops.
* Remove no longer needed default_hwif_transport().
* Cleanup ide_hwif_t from methods that are now in struct ide_tp_ops.
While at it:
* Use struct ide_port_info in falconide.c and q40ide.c.
* Rename ata_{in,out}put_data() to ide_{in,out}put_data().
There should be no functional changes caused by this patch.

To: linux-ide; +Cc: Bartlomiej Zolnierkiewicz, linux-kernel
* Add struct ide_host which keeps pointers to host's ports.
* Add ide_host_alloc[_all]() and ide_host_remove() helpers.
* Pass 'struct ide_host *host' instead of 'u8 *idx' to
ide_device_add[_all]() and rename it to ide_host_register[_all]().
* Convert host drivers and core code to use struct ide_host.
* Remove no longer needed ide_find_port().
* Make ide_find_port_slot() static.
* Unexport ide_unregister().
Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

still on TODO:
- fix ide_host_register() to fail only if it cannot add all ports
- add ide_host_add() which does ide_host_alloc() + ide_host_register()
- add ide_host_free() for freeing ide_hwifs[]'s slots and host instance
