d2f154c95e Add a uart attachment/syscons keyboard driver for sun keyboards. In theory
this will work with any uart backend, currently supported hardware uses
either ns8250 or z8530.

2bec1c8919 Hook-up the uart(4) driver to the build. For a detailed description
of what uart(4) is and/or is not see the initial commit log of one
of the files in sys/dev/uart (or see share/man/man4/uart.4).

Note that currently pc98 shares the MD file with i386. This needs
to change when pc98 support is fleshed-out to properly support the
various UARTs. A good example is sparc64 in this respect.

We build uart(4) as a module on all platforms. This may break
the ppc port. That depends on whether they do actually build
modules.

To use uart(4) on alpha, one must use the NO_SIO option.

1d80cb1b37 Add the new sparc64 OFW PCI framework, conditional on options OFW_NEWPCI
for now. It introduces a OFW PCI bus driver and a generic OFW PCI-PCI
bridge driver. By utilizing these, the PCI handling is much more elegant
now.

The advantages of the new approach are:
- Device enumeration should hopefully be more like on Solaris now,
  so unit numbers should match what's printed on the box more
  closely.
- Real interrupt routing is implemented now, so cardbus bridges
  etc. have at least a chance to work.
- The quirk tables are gone and have been replaced by (hopefully
  sufficient) heuristics.
- Much cleaner code.

There was also a report that previously bogus interrupt assignments
are fixed now, which can be attributed to the new heuristics.

A pitfall, and the reason why this is not the default yet, is that
it changes device enumeration, as mentioned above, which can make
it necessary to change the system configuration if more than one
unit of a device type is present (on a system with two hme cars,
for example, it is possible that hme0 becomes hme1 and vice versa
after enabling the option). Systems with multiple disk controllers
may need to be booted into single user (and require manual specification
of the root file system on boot) to adjust the fstab.
Nevertheless, I would like to encourage users to use this option,
so that it can be made the default soon.

In detail, the changes are:
- Introduce an OFW PCI bus driver; it inherits most methods from the
  generic PCI bus driver, but uses the firmware for enumeration,
  performs additional initialization for devices and firmware-specific
  interrupt routing. It also implements an OFW-specific method to allow
  child devices to get their firmware nodes.
- Introduce an OFW PCI-PCI bridge driver; again, it inherits most
  of the generic PCI-PCI bridge driver; it has it's own method for
  interrupt routing, as well as some sparc64-specific methods (one to
  get the node again, and one to adjust the bridge bus range, since
  we need to reenumerate all PCI buses).
- Convert the apb driver to the new way of handling things.
- Provide a common framework for OFW bridge drivers, used be the two
  drivers above.
- Provide a small common framework for interrupt routing (for all
  bridge types).
- Convert the psycho driver to the new framework; this gets rid of a
  bunch of old kludges in pci_read_config(), and the whole
  preinitialization  (ofw_pci_init()).
- Convert the ISA MD part and the EBus driver to the new way
  interrupts and nodes are handled.
- Introduce types for firmware interrupt properties.
- Rename the old sparcbus_if to ofw_pci_if by repo copy (it is only
  required for PCI), and move it to a more correct location (new
  support methodsx were also added, and an old one was deprecated).
- Fix a bunch of minor bugs, perform some cleanups.

In some cases, I introduced some minor code duplication to keep the
new code clean, in hopes that the old code will be unifdef'ed soon.

00aabd830d - Remove unused cache flushing routines. These will not necessary work
on future UltraSPARC cpus for which the data cache is not direct mapped.
- Move UltraSPARC I and II (spitfire, blackbird, sapphire, sabre) specific
  functions to spitfire.c, and add cheetah.c for UltraSPARC III specific
  functions.  Initially just cache flushing, but there are a few other
  functions that will need to move here.
- Add an ipi handler for data cache flushing on UltraSPARC III.
- Use function pointers to select the right cache flushing functions based
  on cpu_impl.

With this it is possible to boot single user from an mfs root on UltraSPARC
III systems, including spinning up secondary processors.  There is currently
no support for the host to pci bridge, and no documentation for it is
publically available.

Thanks to Oleg Derevenetz for providing access to a system with UltraSPARC
III+ cpus.

012d9539bf Add drivers for the central and fhc busses found in enterprise class
UltraSPARCs, and an eeprom attachment for fhc, which allows the date
to be set properly on these machines.  Central is a wierd bus which
seems to only ever have 1 fhc attached to it.   FHC (FireHose Controller)
is another wierd bus with various things on it depending where its attached.
The fhc attached to central has eeprom and zs, and the fhcs which attach
directly to nexus have simm-status, environment and other nodes, none of
which I'll probably ever have documentation for.

Thanks to Ade Lovett for providing access to an 8 cpu e4500.

e381d2455b Add kernel dump support, based on the ia64 version (which was committed
as sparc64/sparc64/dump_machdep.c a while back).
Other than ia64 (which uses ELF), sparc64 uses a homegrown format for
the dumps (headers are required because the physical address and size of
the tsb must be noted, and because physical memory may be discontiguous);
ELF would not offer any advantages here.

3bd6561289 NB: This commit does *NOT* make GEOM the default in FreeBSD
NB: But it will enable it in all kernels not having options "NO_GEOM"

Put the GEOM related options into the intended order.

Add "options NO_GEOM" to all kernel configs apart from NOTES.

In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.

There are currently three known issues which may force people to
need the NO_GEOM option:

boot0cfg/fdisk:
        Tries to update the MBR while it is being used to control
        slices.  GEOM does not allow this as a direct operation.

SCSI floppy drives:
        Appearantly the scsi-da driver return "EBUSY" if no media
        is inserted.  This is wrong, it should return ENXIO.

PC98:
        It is unclear if GEOM correctly recognizes all variants of
        PC98 disklabels.  (Help Wanted!  I have neither docs nor HW)

These issues are all being worked.

1982efc5c2 Merge the code in pv.c into pmap.c directly. Place all page mappings onto
the pv lists in the vm_page, even unmanaged kernel mappings.  This is so
that the virtual cachability of these mappings can be tracked when a page
is mapped to more than one virtual address.  All virtually cachable
mappings of a physical page must have the same virtual colour, or illegal
alises can be created in the data cache.  This is a bit tricky because we
still have to recognize managed and unmanaged mappings, even though they
are all on the pv lists.

d74ac6819b Compromise for critical*()/cpu_critical*() recommit. Cleanup the interrupt
disablement assumptions in kern_fork.c by adding another API call,
cpu_critical_fork_exit().  Cleanup the td_savecrit field by moving it
from MI to MD.  Temporarily move cpu_critical*() from <arch>/include/cpufunc.h
to <arch>/<arch>/critical.c (stage-2 will clean this up).

Implement interrupt deferral for i386 that allows interrupts to remain
enabled inside critical sections.  This also fixes an IPI interlock bug,
and requires uses of icu_lock to be enclosed in a true interrupt disablement.

This is the stage-1 commit.  Stage-2 will occur after stage-1 has stabilized,
and will move cpu_critical*() into its own header file(s) + other things.
This commit may break non-i386 architectures in trivial ways.  This should
be temporary.
