de540622df Add a pseudo device which allows to access the OpenFirmware device tree
via ioctl()s. This was ported from NetBSD and adapted a bit to better
match our OpenFirmware support code.

7812d86f03 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

d96118005f Basic OpenFirmware disk driver. It will attach to anything in OpenFirmware
that declares itself to be a disk, which may be the wrong thing to do in
the long term but it works well enough to attach to emulated disks in the
PowerPC simulator in gdb now that they have the proper device_type
property.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

47a1c91514 Move the make_dev call from the cn_probe to a sysinit that runs at
SI_SUB_DRIVERS.  cnprobe is too early.

cbecdd5743 1. Lower the poll timeout for the ofw console driver from hz / 50 to hz / 4.
This gives a bit of a sluggish console, but it prevents the console from
   getting stuck if we poll too fast, as well as other badness on certain
   machines.
2. Fix a test for != 0 that should have been > 0.

398e05ab1c 1. Add ofw_pci.h with definitions for the OpenFirmware PCI bindings
2. Add OF_getprop_alloc(), a helper function that will malloc() a sufficient
   amount of memory and then retrieve a property value into it.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

8aa920fd1d Make the openfirmware functions work on 64 bit architectures by using
a standard cell_t type for the fields of all argument structs.  Also
make ihandle_t and phandle_t unsigned to avoid sign extension problems.

707fed2004 OpenFirmware kernel support, as used by the PowerPC and hopefully other
ports later on.

This includes the basic MI interface routines as well as a console driver.
The MD code is kept in the MD directories.

4cc1860f9b OpenFirmware/PowerPC loader, part 2.
As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts
and talks to BOOTP/NFS servers.

(main.c was moved from boot/ofw/libofw to boot/ofw/common but has no revision
 history)
