db36913c87 The code that creates/destroys SGMAP DMA maps is the same; put it 
in a common place and share it.

851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

f363b73f87 Add support for the AlphaServer 2100 (Sable) and the AlphaServer 2100A 
(Lynx), written from scratch by me over a year ago, but never committed
to the tree because there was a bug I could never quite find.  I have
fixed a few problems in the code, but still don't know if that bug is
quite fixed.  Since I don't have access to the hardware directly, I'll
have to call for testers again.

ad4f387a4c Put back the INITIALLY_{ENABLED,LEVEL_TRIGGERED}() PROM brain-damage 
work-around.  It's required in order for the DEC Multia (a very
brain-damaged little machine) to work properly.

Submitted by Juergen Weiss <weiss@uni-mainz.de>, addresses
port-alpha/11202.

d615083897 The AMD 751 doesn't have DMA windows, so allocate the RAM out of the 
PCI memory extent map.  Bad things will happen if we try to assign
a device where RAM is mapped into PCI space.

249773b538 Deal with another odd need of the Sable/Lynx systems, which need to 
have an ISA chipset present before the PCI-EISA bridge has been
attached (because the STDIO module has an ISA DMA-using device,
the floppy controller, connected to it).

cc9dfe871b Do the previously slightly differently, to avoid confusing the internal

send me an EV6 machine!)

9a2d9ff68b Because of the Cool sign-extension hack we use to access PCI space, 
the `get window' method ends up with the wrong physical address to
pass onto userspace (which wants to mmap the space).

Compensate by adding a CHIP_PHYSADDR() macro which un-hacks the address
suitably for mapping with other-than-KSEG.

df88882d80 - Add a bus space method for getting the translation for a window. 
- Add sysarch methods for "get bus window count", "get bus window",
  and "pci conf read/write".

These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.

781149bb12 Handle the case where PCI dense memory and PCI sparse memory don't 
overlap; don't require allocation from the dense extent if the PCI
memory address isn't mapped into dense space.

Also, make sure to return an error if a liner mapping is requested
and dense space is not available (not just not requested).
