    Hm, how does it help if you don't make it into driver's method? :-O

This was meant to be a preparation before converting palm_bk3710 to
use struct ide_port_info.  On the second thought this change may be as
well integrated into the future patch (which I'll try to cook later
today, unless somebody beats me to it ;-).

Thanks,
Bart

Subject: [PATCH] palm_bk3710: use struct ide_port_info

* Factor out cable detection to palm_bk3710_cable_detect().

* Add palm_bk3710_init_hwif() (->init_hwif method implementation).

* Remove needless ->quirkproc initialization.

* Add missing ->pio_mask initialization.

* Use ATA_* defines for setting ->{ultra,mwdma}_mask.

* Add 'struct ide_port_info palm_bk3710_port_info' and pass it to
  ide_device_add().  Then remove open-coded 'hwif' initialization.
