57467e5933 Fix interrupt handling. It started off broken and grew worse over time.
The rewrite of the interrupt handler includes:
o   loop until all pending interrupts are handled. This closes a
    race condition.
o   count the number of interrupt sources we handled so that we can
    properly return FILTER_HANDLED or FILTER_STRAY when we break out
    of the loop.
o   When matching the interrupt source to the devices that have that
    source pending, check only from the set of devices we found to
    have a pending interrupt.

11a12794a9 Add support for the Oxford OX16PCI958-based card.
Note, that the patch provided with this card for the Linux states that
the card uses DEFAULT_RCLK * 2, while in fact it is '* 10'.  So probably
we should also use the subdevice/subvendord here. For now just ignore
that fact.

1454b5785e The SIIG 4 port serial card based on the Oxford OX16PCI954 is
clocked at 10x normal speed. That is, when you set it for 9600
baud, it actually does 96000 baud. In order to make it plug and
play with other serial ports, it has to have its clock rate
reduced by a factor of 10.

64220a7e28 Rewrite of puc(4). Significant changes are:
o  Properly use rman(9) to manage resources. This eliminates the
   need to puc-specific hacks to rman. It also allows devinfo(8)
   to be used to find out the specific assignment of resources to
   serial/parallel ports.
o  Compress the PCI device "database" by optimizing for the common
   case and to use a procedural interface to handle the exceptions.
   The procedural interface also generalizes the need to setup the
   hardware (program chipsets, program clock frequencies).
o  Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
   default and non-serdev devices are handled by the bus.
o  Use the serdev I/F to collect interrupt status and to handle
   interrupts across ports in priority order.
o  Sync the PCI device configuration to include devices found in
   NetBSD and not yet merged to FreeBSD.
o  Add support for Quatech 2, 4 and 8 port UARTs.
o  Add support for a couple dozen Timedia serial cards as found
   in Linux.

c46a4f9afd Careful measurement of the ST Labs card shows that the pulse width of
transmitted bits was between 8.6180us and 8.6200us when we used a RCLK
of 16.500MHz.  This is a little low (should be 8.6805us).  This error
is exactly the error one would expect if it actually had a 16.384MHz
watch oscillator (as suggested by garrett) instead of using the PCI
RCLK.  Assume that the pci clock therefore wasn't really used, but
instead the cheap 16.384MH watch quartz oscillator.  This gives bits
in the 8.6800us to 8.6810us ranage, which matches theoretical.

7640c87195 The Oxford 16C950 based CardBus Serial device that I was given some
time ago appears to be based not on the typical 1.8432MHz clock, or
the other more typical multiple of 8 of this (14.7456MHz), but instead
it appears to be 1/2 the PCI clock rate or 16.50000MHz.  I'm not 100%
sure that this is right, but since I did the original entry, I'm going
to go ahead and modify it.  With the 14.7456MHz value, I was getting
bits that were ~7.3us instead of ~8.6us like they are supposed to be.

My measuring gear for today is a stupid handheld scope with two
signficant digits.  So I don't know if it is 33.000000/2 MHz or some
other value close to 16.5MHz, but 16.5MHz works well enough for me to
use a couple of different devices at 115200 baud, and is a nice even
multiple of a well known clock frequency...

7417e80b4e Don't enable PUC_FASTINTR by default in the source. Instead, enable it
via the DEFAULTS kernel configs.  This allows folks to turn it that option
off in the kernel configs if desired without having to hack the source.
This is especially useful since PUC_FASTINTR hangs the kernel boot on my
ultra60 which has two uart(4) devices hung off of a puc(4) device.

I did not enable PUC_FASTINTR by default on powerpc since powerpc does not
currently allow sharing of INTR_FAST with non-INTR_FAST like the other
archs.

64fd97df54 puc(4) does strange things to resources in order to fool the
subdrivers to hook up.

It should probably be rewritten to implement a simple bus to which
the sub drivers attach using some kind of hint.

Until then, provide a couple of crutch functions with big warning
signs so it can survive the recent changes to struct resource.

c90ff9ce5a - sparc64/fhc/fhc.c:
Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
  IRQs of children. This works similar to e.g. sbus(4), i.e. add the
  IRQ resources as fully specified to the resource lists of the children,
  allocate them like normal. When establishing the interrupt search the
  interrupt maps of the children for a matching INO to determine which
  map we need to write the fully specified interrupt number to and to
  enable the mapping (before the RID was used to indicate which interrupt
  map to use).

- dev/puc/puc.c:
  Revert rev. 1.38, with the above change fhc(4) no longer needs special
  treatment for allocating IRQs.

099894cc96 Declare the sbus(4) front-end of puc(4) also for fhc(4), allowing
uart(4) to support the Zilog 8530 SCCs which hang off of a FireHose
bus on Sun E4000/E5000 class machines.
Beside the fact that a puc_fhc.c would just be a copy of puc_sbus.c
with s,sbus,fhc,g the reason why the declaration for fhc(4) was
sticked into puc_sbus.c is that both of these front-ends for puc(4)
will go away once there is a scc(4).
