* Convert legacy host drivers to use struct ide_port_info + ide_device_add()
instead of open-coding initialization of IDE port data structures.
* Add ->cable_detect method for cable detection + use it in PCI host drivers.
* Fix some bugs in the process (handling of "idex=ata66" in atiixp, cs5535
and scc_pata and handling I/O 32-bit setting in dtc2278 and au1xxx-ide).

On DTC2278 32-bit I/O has to be enabled for both devices on the port
so always enable it during init time and disallow further changes.

Interesting... this driver's support for SWDMA0 is broken since the cycle
should be 960 ns long, not 480, and SWDMA2 is underclocked using the same
cycle as SWDMA1, 480 ns...

Hm, I wonder which value it will assume, 0x07 or 0? Not sure even after

Why check for (d == NULL) every time and not do it once and break from the

This is tricky since it depends on the CRIS version
(0x07 on CRIS V32 and 0x00 on CRIS V10).

The driver supports *4* channels and it didn't set ->channel at all.
Since in the meantime ide-cris got marked as BROKEN I guess that a patch
removing above code would be OK.

To save on some code lines and resulting code size
(ide_device_add_all is not performance critical).

It might be too late, but "host_flags && IDE_HFLAGS_NO_DMA" seems
wrong for me.

It is too late for -git but not too late for 2.6.25-rc1. ;-)

Fix regression caused by commmit c413b9b94d9a8e7548cc4b2e04b7df0439ce76fd

Underclocking the DMA is not a problem - if you look at the timing
diagrams and associated tables in the ATA specifications, you'll
find that they specify the *minimum* cycle timings.
However, you're correct that SWDMA0 is not able to be supported.
