bouyer 0c3ecf8e5e Improve Ultra/66 support now that I've got some docs from Promise. 1999-11-28 20:05:18 +00:00
bouyer 52068f73ce Add support for the Promise Ultra/33 and /66 pci IDE controller. In addition to
chip-dependant code this required the following changes:
- Instead of attaching the device in a generic way with some chip-dependant
  routines, use a chip-dependant attach routine with some common code
  factored out. The code is marginally bigger, but this allows the CMD64x
  flag hack to go away.
- For chips that report per-channel 'irq triggered', test this before calling
  wdcintr() for the native-pci irq case (compat intr can't be shared),
  as wdcintr() has no good way to know if a irq was for it or not, and
  ends up with irq loss. XXX for chips that don't have this feature irq sharing
  will not work properly !
- add my copyrigth notice (could have been done some time ago I think :)

There are still some issues to be solved with the Promise controller and
ATAPI devices.
Many thanks to Paul Newhouse for shipping me 2 Ultra/33 boards for doing this
work.
