All of Oxford/PLX OX16PCI954, OXm16PCI954 and OXu16PCI954 share the
exact same (subsystem) device and vendor IDs. However, the reference
design for the OXu16PCI954 uses a 14.7456 MHz clock (as does the EXSYS
EX-41098-2 equipped with these), while at least the OX16PCI954 defaults
to a 1.8432 MHz one. According to the datasheets of these chips, the
only difference in PCI configuration space is that OXu16PCI954 have
a revision ID of 1 while the other two are at 0. So employ the latter
for determining the default clock rates of this family.
Note that one might think that the actual clock could be derived from
the Clock Prescaler Register (CPR) of these chips. Unfortunately, this
is not that case and its use and content are orthogonal to the frequency
of the crystal employed.
Tested with an EXSYS EX-41098-2, which identifies and attaches as:

- Apparently, r186520 was just wrong and the clock of Oxford OX16PCI958 is
neither DEFAULT_RCLK * 2 nor DEFAULT_RCLK * 10 but plain DEFAULT_RCLK
and there's no (open) source indicating otherwise. This was tested with
an EXSYS EX-41098-2, whose clock is not configurable and identifies as:

Note that this exactly matches the card mentioned in PR 129665 so no
sub-device/sub-vendor based quirking of the latter is possible. So maybe
we should grow some sort of tunable, in case non-default cards such as
the latter aren't configurable either (this also wouldn't be the first
time an allegedly tested commit turns out to be wrong though).

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.

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.

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...

Add yet another entry to the list.

Sort Oxford Semi entires. Add entry for OXCB950, a PCI/CardBus
16C950. Adding it here doesn't unlock any of the cool 16C950 features
(like the 128 byte fifo, the different prescalor, etc), but it does
seem to get it working for me in light testing.

o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530)
to handle different hardware and determine resource sizes.
o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both
are used by uart(4) to get sufficient information to talk to the HW.
o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O
if I/O port space cannot be allocated, or vice versa.
o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching
to sio(4) fails (due to not having the sio driver).
o Put struct puc_device_description in struct puc_softc instead of
having a pointer to a device description in the softc. This allows
us to create device descriptions on the fly without having to use
malloc() or otherwise have them staticly defined.
o Move puc_find_description() from puc.c to puc_pci.c as it's specific

puc stands for PCI, so we kinda mess things up here. It's too soon

Add the puc (PCI "Universal" Communications) driver. The idea and some of
the structure definitions come from NetBSD to make it easier to share card
definitions. The driver only acts as a shim between the pci bus and the
sio driver. Later pci parallel ports could also be supported through this
driver. Support for most single and multiport pci serial cards should be
as simple as adding its definition to pucdata.c

Tested with the following pci cards:
Moxa Industio CP-114, 4 port RS-232,RS-422/485
Syba Tech Ltd. PCI-4S2P-550-ECP, 4 port RS-232 + 2 parallel ports
Netmos NM9835 PCI-2S-550, 2 port RS-232
