I put newer patch.

  ftp://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/tmp/pciide_cardbus_support.diff

First, current pciide(4)s (ex. satalink, viaide) is depends on pci.
However, we know SATA can be connected externally.  It means 'pciide at
cardbus' is in a word necessary.

We are timing in which it thinks about the structure of pciide now.

I think the following two methods.

  1. The variables for cardbus is added to pciide_softc.
  2. Split pciide_pci/pciide_cardbus.  pciide_pci_softc and
     pciide_cardbus_softc including pciide_softc are made.

I made the patch of the former. The latter might be better. However, I
think that it is very serious to do this correction.


Thanks,
