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.

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.

- Use BAR2 rather than BAR0 for the Rocketport UPCI 8O card. I suspect
that other UPCI cards might need to use BAR2 as well.

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.

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.

7. Fix the baud_table.

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.
