4e5adf5f4a Part of AS2100 support that I neglected to commit last night

6ab09a6376 Add AlphaServer 2000 (demi-sable), 2100 (sable), and 2100A (lynx) support.
Only PCI and on-board ISA peripherials are supported at this time.

This support has been only lightly tested due to a lack of response to my
call for testers on the freebsd-alpha mailing list.  It works quite well
on the one AS2100 on which it has been tested, but it may not work on
an AS2100A and should therefore be regarded as experimental.

7b7f33c4c3 Handle PCI devices that actually use an ISA IRQ for the cia and tsunami
chipsets.  An example of this is the USB controller on these chipsets.
With this, I can now use USB devices on the test Alpha I am borrowing at
the moment.

6499b39e60 Alpha 8200: Add in a dummy child of dwlpx so that we can make the leap
from DWLPX to PCI space. Just a methods holder such that we have a parent
which is a "pcib" and we create a child which is a "pci". Add the appropriate
ivar code (which is for a hose #).

9ca20275e0 Alpha 8200: Do some compilation cleanup. Conditionalize some IDE stuff
based upon presence/absence of ISA (there is no ISA bus on an 8200- okay,
well, there *could* be one in a DWLPX tray, but we don't support it)).

Most importantly change the interrupt resource map to cover a whole 16
bits. The 8200 uses 16 bit interrupt vectors which we construct that
contain the I/O-board, hose, an pci slot in them, and then we write these
vectors into the appropriate DWLPX registers. At any rate, a flat array
of 64 'IRQs' isn't enough.

47351d2774 Update the ata driver to take more advantage of newbus, this
was needed to make attach/detach of devices work, which is
needed for the PCCARD support.
(PCCARD support is still not working though, more to come on that)

Support the CMD646 chip which is used on many alphas, sadly only
in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes.

Lots of cosmetic fixes here and there.

Sorry for the size of this megapatchfromhell but it was not
possible otherwise...

e1364adbae Make devices behind PPBs work on DS10s (and any other single pchip tsunamis)
I was wagering on DEC being elegant & numbering PCI buses normally on
machines with one pchip.  It looks like they went with consistent -- buses
behind ppbs begin with bus 2.

7c79b9ff14 Improve the mapping between the hardware PCI bus numbering on multi-hose
tsunami systems and the PCI bus-numbering system of FreeBSD.  Eg, the former
allows for 2 PCI bus 2's (one each on hoses 0 and 1) while the latter
needs to give each PCI bus a unique monotonically increasing number.

It has been fairly well tested and correctly maps machines with a ppb on
hose 1 as well as machines with ppbs on both hoses.

DS10s remain untested, as I do not have a pci card with a ppb which will
pass POST in a tsunami.

This is a house of cards.

fe0d408987 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
the rest of the local changes in my tree.

6cf898c767 Mchines whose interrupts are not routed through the ISA pic were still
registering their interrupts with rman as though they were going through
the ISA pic.  This prevents a conflict between isa & pci for irqs on such
machines.

Also hookup the chipset struct before calling platform.pci_intr_init().
This allows me to call inw/outw down in the platform code.

Add interrupt printfs to match the CIA chipset.

160dd8eb7b Add a second direct map window to increase the maximum RAM this platform
can deal with from 1GB to 2GB.   I have no way to test with >1GB because I
don't have high enough density memory to get any one box over 1GB.  However, I
have tested it on xp1000 & ds10 with < 1GB of memory & have verified that it
does no harm.

923502ff91 useracc() the prequel:
Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>.  This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their

This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.

da7ca2d9bd allow pci_ioctl to work with multi-hose alphas.
Rather than teaching pci_ioctl about hoses, we just pass down a magic number

a76245d21d This fix allows cards inserted in one of the bottem-most slots on an xp1000
(behind the built-in ppb on hose 1) to be found:

When testing the adaptec controller on alpha, I realized I misread the xp1000
documentation and the way I'm calculating the bus number for PCI
config space accesses on the tsunami is wrong.  I had thought that a bus
behind a ppb should be numbered as the nth bus in that hose, but it
actually needs to be the nth global bus within the system.  The bus number
for the primary bus on a hose must always remain 0 when calculating config
space addresses.

equivalent to SYS_RES_MEMORY for x86 but for alpha, the rman_get_virtual()

54a8c69347 Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.
