The last change for partport_pc did fix the common case for all PowerMacs,
but it broke the case for PCI multiport IO cards. In fact, the config
option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed
the parport driver. It enables the winbond and smsc probing.
Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will
take care of it. All powerpc configs should have
CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp
boards we tested it on.
Tested on a G4/466 with a PCI card:

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can
boot one single binary on pseries and G5 boards. pmac has no legacy io,
probing for PC style legacy hardware (or accessing the legacy io area
regulary) may lead to a hard crash:
* add check for parport_pc, exit on pmac. 32bit chrp has no
->check_legacy_ioport, the probe is always called. 64bit chrp has
check_legacy_ioport, check for a "parallel" node
* add check for isapnp, only PReP boards may have real ISA slots. 32bit
PReP will have no ->check_legacy_ioport, the probe is always called.
* update code in i8042_platform_init. Run ->check_legacy_ioport first,
always call request_region. No functional change. Remove whitespace
before i8042_reset init.

Remove the assumption that pnp_register_driver() returns the number of devices
claimed.
parport_pc_init() does nothing with "count", so remove it. Then nobody uses
the return value of parport_pc_find_ports(), so make it void. Finally, update
pnp_register_driver() usage.

The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.
It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)
I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo
controller cards. this implementation doesn't work for nm9855 based cards!
there are two reasons:
a) the module 'parport_pc' doesn't want to give the resonsibility for
the netmos_9855 to 'parport_serial' and can not handle the serial lines
-- trivial to fix...
http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html
http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in
'parport_serial' still doesn't work because of wrong assumptions about
the relevant BARs port address layout for this chip:
0000:00:09.0 Communication controller:
NetMos Technology PCI 9855
Multi-I/O Controller (rev 01)
(= 9710:9855)
Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014)
Flags: medium devsel, IRQ 177
I/O ports at a800 [size=8] (= parport)
I/O ports at a400 [size=8]
I/O ports at a000 [size=8] (= serial)
I/O ports at 9800 [size=8] (= serial)
I/O ports at 9400 [size=8] (= serial)
I/O ports at 9000 [size=16] (= serial)
the following patch will fix the problem.

Part of parport_pc that uses ISA DMA helpers made conditional on
CONFIG_ISA_DMA_API. As the result, driver got usable for boxen that do
not have ISA DMA stuff and have normal PCI parport card stuck into
them - these never use DMA anyway.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
