73d398d702 Change the device path representation in libofw to use the full firmware
path, instead of an internal i386 specific one.  Don't try to interpret
a disklabel in ofw_disk.c, open the partition's device node directly and
let the firmware do it.  This fixes booting from a partition other than 'a'
on sparc64, which is needed to support more installation methods.

44423651cb Major rework of how we copy data into kernel space.
We now talk to the memory and mmu instances directly rather than using the
OpenFirmware "claim" method.

1b23a3102e Back out last commit. I expect our bsd.*.mk gods to remove the need for
defining so many extra things in addition to INTERNALLIB.  We don't like
repetitive C code and we shouldn't for make code either.

9b110cfade Change the disk probing so that it will actually find disks other
than the first one on a controller, and work for secondary
controllers.
Due to the prom not having nodes for each disk, but a catch-all one,
we have to iterate over each device, trying to open it to determine
whether it is actually present.
Since probing this way takese some time (and spews some spurious
warnings), it should maybe be short-circuited if we use the
device we were booted from.
Implement lazy device probing, and correct slice/partiniton
handling in the ofwd_open() code. With this, I can now actually boot
a kernel from disk, and the loader does not create unnecessary
delays.

e187f56a06 Check the return values of index() and don't dereference it if its null;
the path may not have a ':' in it.  The mac address property is called
mac-address for sparc64.  Don't allocate a dma buffer for sparc64 either.

7e57a5d41a - Remove unneeded variable.

   the last commit; I am having problems booting when multiple SCSI
   disks are attached, so I will change this part as soon as I find
   a solution, anyway.

36d5064113 - Do not include a NetBSD header as it is not needed anymore.
- Remove two constants that were needed in conjuction with the
   NetBSD disklabel header.  Use the FreeBSD equivalents.
   To boot from NetBSD/sparc64 partitions, define LABELOFFSET to
   be 128.
 - Do not use the complete open firmware path to filter out cdrom drives.
   No path containing "cdrom" is detected as a disk now.
 - Simplify some code.

994f7977f1 Mega-patch for OpenFirmware loader support.
- Flesh out ofw_readin routine.
- Add OpenFirmware load and exec routines.
- Make sure memory allocation for the kernel is done correctly.
- Change the way the heap is allocated so as to make it easier to deallocate
  when we hand over.
- Add a command to print memory maps similar to the one for ia64.

With this patch, I can now load and hand over to a kernel on my iMac.  There
are some problems with OpenFirmware routines failing after the hand over that
still need to be addressed.

7d73a33303 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)

087d4857e5 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.

2feae82d78 Bootstrap updates.
- Move some startup code from MD to MI sections
 - Add a 'copyout' and some copyout-related functions.  These will be
   obsoleted when BTX is available for the 386 and the kernel load
   area becomes directly addressable.
 - Add the ability load an arbitrary file as a module, associating
   and arbitrary type string with it.  This can be used eg. for loading
   splash-screen images etc.
 - Add KLD module dependancy infrastructure.  We know how to look for
   dependancies inside KLD modules, how to resolve these dependancies
   and what to do if things go wrong.  Only works for a.out at the
   moment, due to lack of an MI ELF loader.  Attach KLD module information
   to loaded modules as metadata, but don't pass it to the kernel (it
   can find it itself).
 - Load a.out KLD modules on a page boundary.  Only pad the a.out BSS
   for the kernel, as it may want to throw symbols away.  (We might want
   to do this for KLD modules too.)
 - Allow commands to be hidden from the '?' display, to avoid cluttering
   it with things like 'echo'.  Add 'echo'.
 - Bring the 'prompt' command into line with the parser syntax.
 - Fix the verbose 'ls'; it was using an uninitialised stack variable.
 - Add a '-v' flag to 'lsmod' to have it display module metadata as well
   (not terribly useful for the average user)
 - Support a 'module searchpath' for required modules.
 - The bootstrap file on i386 is now called 'loader' to permit the
   /boot directory to use that name.
 - Discard the old i386 pread() function, as it's replaced by
   arch_readin()

815f3686d0 Bootloader update.
- Implement a new copyin/readin interface for loading modules.
   This allows the module loaders to become MI, reducing code duplication.
 - Simplify the search for an image activator for the loaded kernel.
 - Use the common module management code for all module metadata.
 - Add an 'unload' command that throws everything away.
 - Move the a.out module loader to MI code, add support for a.out
   kld modules.

fc79e25bdf This is the new unified bootstrap, sometimes known previously as the
'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
 - The i386 bootstrap only supports booting from a floppy.
 - The kernel and kld do not yet know how to deal with the extended
   information and module summary passed in.
 - PnP-based autodetection and demand loading of modules is not implemented.
 - i386 ELF kernel loading is not ready yet.
 - The i386 bootstrap is loaded via an ugly blockmap.

On the alpha, both net- and disk-booting (SRM console machines only) is
supported.  No blockmaps are used by this code.

Obtained from:	Parts from the NetBSD/i386 standalone bootstrap.
