66631c00de - Use the cell_t type definition for Open Firmware arguments in
combination with requisite casts as this avoids fatal side
   effects on 64-bit architectures.
 - Add the OF_alloc_phys function.

1da9b140b7 - Fill dummy functions with code to read from disk using Open
Firmware.
 - Add a temporary disklabel header to boot off a NetBSD/sparc64
   partition.  This file can be deleted when we have got a FCode
   bootblock.

The disklabel header was obtained from NetBSD.

8716f26121 - Add an ifdef guard.

cae2c81dc2 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.

035dbc3cb5 Pass NULL instead of MAXPHYS to the DMA allocation method. Be a bit more
verbose if we fail to allocate the DMA buffer.

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)

but can't boot from them yet."

Thanks to Stephane Potvin for the some of the code in this set.

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.

e24168e6c3 * Add old UFS compatibility code to alpha/boot1.
* Fix a raft of warnings, printf and otherwise.
* Allocate the correct amount in mod_searchmodule to prevent an overflow.
* Fix the makefiles so they work outside my home directory (oops).

06b57b0e09 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()

c73b70eec4 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.

2b5cfb37f7 Minor tweaks to track a couple of i386 changes and to make it compile. 1998-08-22 10:31:01 +00:00

c2f9d95de5 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.
