d7e5eb3faa Use config's conditional compilation rather than using #ifdefs that make
modular compilation harder.  I'm doing this because people seem to like
cut/pasting examples of bad practices in existing code.

e4a289662a Add another four device ID's for isa pnp modems. The USR's seem to use
the same vendor and logical ID.  The rest I am not sure whether they
are vendor or logical, but it won't hurt if I've put a vendor ID here
as merely will not match.  These came from the old sio-pnp code, hence
the uncertainty about which ID it is.

373ff2297c Don't mark unallocated resources as active; the goal is to reserve them,
and there may be a good reason for them being unallocated (eg. they're
nonsensical or not useful).  The goal here is simply to reserve them
against accidental use by other code.

2196bee6e9 Don't do device_set_desc() until after checking for PnP probes. Otherwise
things like sound cards can get called "Parallel port".  A note to the
unwary; the isa-pnp devices in the system are probed like PCI - each
device ID is passed to *all* isa probe routines to find the best match.
If the driver is not prepared to deal with this, it must abort in this
scenario or it will try and claim all PnP devices.

59fc142474 Port of ppbus standalone framework to the newbus system.
Note1: the correct interrupt level is invoked correctly for each driver.
       For this purpose, drivers request the bus before being able to
       call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus
       core when drivers release it. Thus, when BUS_SETUP_INTR is called
       at ppbus driver level, ppbus checks that the caller owns the
       bus and stores the interrupt handler cookie (in order to unregister
       it later).

       Printing is impossible while plip link is up is still TRUE.
       vpo (ZIP driver) and lpt are make in such a way that
       using the ZIP and printing concurrently is permitted is also TRUE.

Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET
       is now needed to force chipset detection. If set, the flags 0x40
       still avoid detection at boot.

Port of the pcf(4) driver to the newbus system (was previously directly
connected to the rootbus and attached by a bogus pcf_isa_probe function).

715966bf8a Add a new mechanism, cndbctl(), to tell the console driver that
ddb is entered.  Don't refer to `in_Debugger' to see if we
are in the debugger.  (The variable used to be static in Debugger()
and wasn't updated if ddb is entered via traps and panic anyway.)

- Don't refer to `in_Debugger'.
- Add `db_active' to i386/i386/db_interface.d (as in
  alpha/alpha/db_interface.c).
- Remove cnpollc() stub from ddb/db_input.c.
- Add the dbctl function to syscons, pcvt, and sio. (The function for
  pcvt and sio is noop at the moment.)

81d7fdc3a3 Futher cleanup.. "device_print_prettyname(); printf()" -> device_printf()
It seems that the IDE system uses 0x3f6 for itself, which conflicts with
fdc's default 0x3f0-3f7 allocation range. Sigh.  Work around this.
Use bus_set_resource() rather than allocating specific areas, it makes
the code a little cleaner.

e2faa55ecb Make the evil broken pnpbios compensation slightly less evil.
This is the hack that compensates for when bios vendors "forget" to
include the fdc control (0x3f7) port in their io port mappings.  Instead
of accessing ports outside of a range allocated to a handle, simply
allocate the port directly.  It even shows up in the probe..

159a4659df Patch up some of the evilness left over from the early newbus porting.
In particular:
 - Don't leave resources allocated in the probe routine.  Allocate them
   during probe and release them.  Probe's job is to identify devices only.
 - Don't abuse the ivars pointer.. (!).  Create real ivars and use the
   proper access system.  (the bus_read_ivar method)
 - Don't add the children until attach() has successfully grabbed the
   hardware, otherwise there are potential leaks if attach fails.

8bfa846d93 ISA device drivers use the ISA source interrupt number in locations where
the low level interrupt handler number should be used.  Change
setup_apic_irq_mapping() to allocate low level interrupt handler X (Xintr${X})
for any ISA interrupt X mentioned in the MP table.

Remove an assumption in the driver for the system clock (clock.c) that
interrupts mentioned in the MP table as delivered to IOAPIC #0 intpin Y
is handled by low level interrupt handler Y (Xintr${Y}) but don't assume
that low level interrupt handler 0 (Xintr0) is used.

Don't allocate two low level interrupt handlers for the system clock.

b68c18d69f Fixed races accessing the RTC. The races apparently caused
apm_default_resume() to sometimes set a very wrong time.
(1) Accesses to the RTC index and data registers were not atomic enough.
    Interrupts were not masked.  This was only good enough until an
    interrupt handler (rtcintr()) started accessing the RTC in FreeBSD-2.0.
(2) Access to the block of time registers in inittodr() was not atomic
    enough.  inittodr() has 244us to read the time registers.  Interrupts
    were not masked.  This was only good enough until something (apm)
    started calling inittodr() after boot time in FreeBSD-2.0.
The fix for (2) also makes the timecounter update more atomic, although
this is currently unimportant due to the low resolution of the RTC.

6c96f03d92 Extract a list of extra isa pnp modem ID's from NetBSD and OpenBSD. Some
of these are bound to have a PNP05xx compatid, but there's no easy way to
tell.  Since it's just an ID list and uses the pnp header's description
strings rather than encoding strings here, it doesn't seem to be too
expensive to err on the safe side.

367ba76bfd Add a flag to disable FIFO probing. The code seems to have a chance of
misdetecting FIFO capabilities, at least on my girlfriend's Thinkpad 755,
the driver doesn't work using the FIFO.

While i was at it, i (partially) fixed option FCC_YE since it would no
longer have compiled at all under -current.  I've also made an attempt
to document the device driver flags value (ab-)used internally by this
option.

f57de250e0 Add a truely evil workaround (hack!) for some unfortunate BIOS
programming practices.  It seems that newer fdc chips have an
alternative way of setting the transfer speed (including high speed
modes for floppy tape) that doesn't use the control register (which
we don't support - we use the old way only).  So, they (the BIOS
programmers) sometimes leave out the 0x3f6 control register from
the PnP ports descriptor(!!).  "Hey, it works with windows, so
what's the problem?" :-(  Anyway, this hack tries to compensate
for that.  This was discussed with dfr (who did the pnp attachment).

8bc1a5a150 Use bus_get_resource() instead of bus_get_resource_start() as the latter
returns "0" on failure, which is indistinguishable from (say) irq 0.  This
should stop a couple of stray messages that turn up.

Also, if a BUS_SETUP_INTR() fails with INTR_TYPE_FAST, try falling back to
a normal interrupt.  This might help pccard folks with a shared slot
interrupt.  This whole thing needs to be revisited.

87e31f4b90 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from

737361b49b Fix the hang on card eject problem and maybe the hang on suspend
problem.

o Create new timeout routine so we don't detach the card inside a ISR
  but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
  it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
  than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
  if_down.  if_detach destroys the device, while if_down just marks it
  down.  In this incarnation of the pccard things, we map the disable
  the slot action to detach the driver, which removes the driver from the
  device tree.  When that is done, a panic would soon follow as the
  ifconfig tried to down the device.

Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called.  sio's softc used
  to be statically allocated, so you could check sc->gone, but that is
  now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.

Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)
