858b72dbb8 Use the callout(9) API instead of timeout(9). To do this more cleanly,
convert a global timer to a per-controller timer.  This works much better
with locking and removes the need for several global lookup tables.

c68534f1d5 Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register.  The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR.  Thus, the bit is no longer
a reliable indication of capability, and should not be checked.  This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

520998911a These checks against BUSY aren't needed: the newbus layer does this
already with the appropriate locks held...  There's no need to do it
here, so just delete the checks.

a18c284294 Start to convert this over to the new tty layer. These changes allow
this driver to compile and limp along with the new layer.  These changes
do not deal with proper locking around access to the HW.  This is only
a starting point.  I have not tested modem control but tip seems to work
okay and I can send and receive characters which I needed for one of my
-current boxes.  I have not tied this driver back up to the build since
I don't want people to think it is ready for prime time.  If anyone
else has some cycles to work on this feel free to!

Also add support for a 16 port PCI interface I have at work.

04f716a436 - Use pci_get_device() and pci_get_vendor() when we only want one part
of the device id.
- Use BAR2 rather than BAR0 for the Rocketport UPCI 8O card.  I suspect
  that other UPCI cards might need to use BAR2 as well.

d2b677bb1a Use BUS_PROBE_DEFAULT in preference to 0 and BUS_PROBE_LOW_PRIORITY in
preference to some random negative number to allow other drivers a
bite at the apple.

d6a774ca4a Prevent the rp driver from panic'ing on first access and make at
least the pci device unloadable

- Use ttymalloc() rather than a plain  malloc to allocate the
  rp->rp_tty ttys.  This is now required due to the recent locking
  changes to ttys and prevents a panic due to locking an unitialized
  t_mtx.

- Allow the pci driver to be unloaded.  This involved moving
  the call rp_releaseresource() to the end of rp_pcireleaseresource(),
  since rp_pcireleaseresource() uses ctlp->dev, which is freed
  by rp_releaseresource().

- Allow the generic part of the driver to be unattached by providing
  a hook to cancel timeouts.

38d8c9940b Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

1f82d2d70d 1. Update Comtrol RocketPort driver(rp) to version 3.02.
2. Newbusify the driver.
3. Build as a module.

4. Use correct minor numbers when creating device files.
5. Correctly lock control characters.
6. Return ENXIO when device not configured.
Submitted by:	Tor Egge	<Tor.Egge@fast.no>

7. Fix the baud_table.
Submitted by:	Elliot Dierksen	<ebd@oau.org>

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
  revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
