 1.17  14-May-2022  hgutch PR 56829: Fix "map" call to Open Firmware and no longer mess up OFW stack.
This unbreaks miniroot.fs.

Thanks to Björn Johannesson for originally pointing this out and to
mrg@ for pointing out the actual issue and suggesting a fix.
 1.16  15-Sep-2017  martin Add more details about the boot device as a new bootinfo record type.
From within the bootloader, when we have readily accessible instance
handles of the boot device, it is easy to query more details like SCSI
LUN, target, and FC-AL wwn from the firmware.
The kernel later would have a hard time getting theses, but can make good
use to match the boot device.
 1.15  10-Oct-2015  martin Add compile time asserts to make sure we have properly picked up types
for a 64bit cpu and 64bit openfirmware.
 1.14  27-Mar-2015  nakayama Fix kernel loading failures from partitions started from over first
4GB of disks on sparc64.
 1.13  18-Dec-2013  martin branches: 1.13.4; 1.13.6;
The "close" call returns no arguments
 1.12  21-May-2011  tsutsui branches: 1.12.4; 1.12.10; 1.12.14; 1.12.16; 1.12.18; 1.12.24;
WARNSfy and fix dumb bugs noticed by warnings.
 1.11  18-May-2009  nakayama branches: 1.11.4; 1.11.6;
Make ofwboot can handle over 4GB physical memory by using OpenFirmware
calls properly, and some cosmetic changes. Idea from OpenBSD.
 1.10  17-Oct-2007  garbled branches: 1.10.20; 1.10.30; 1.10.40; 1.10.44;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.9  19-Sep-2007  martin Some aliases (like "cdrom") expand to a path that includes a partition -
deal with them.
 1.8  13-Jul-2006  uwe branches: 1.8.14; 1.8.22; 1.8.32; 1.8.34;
De-__P. ANSIify.

Same object code is generated (except in prf.c, where putchar argument
type was changed to int to match the prototype and one instrcution
changes accordingly).

strategy() in ofdev.c was not ANSIified in this sweep, b/c that
changes code generated at call sites!
 1.7  27-Jan-2006  cdi branches: 1.7.2; 1.7.6;
Alter sparc64 bootstrap:

- Map kernel with permanent 4MB pages to ease kernel's life
- Pass mappings down to the kernel as part of bootinfo structure
- Try to detect whether kernel is aware of the new boot scheme or not and
in the former case map the kernel using OpenFirmware and do not pass
bootinfo structure
- Provide -C switch to force compatibility mode if autodetection fails
- While on this, fix PR #25763: If load of default kernel fails, try one by
one those specified in compiled-in list

Much inspired by the bootloader of FreeBSD, with some imported code from there.
 1.6  11-Dec-2005  christos branches: 1.6.2;
merge ktrace-lwp.
 1.5  01-Jun-2005  martin branches: 1.5.2;
Adapt to constification
 1.4  16-Jan-2005  chs remove some dead code, simplify and wrap some long lines.
 1.3  27-Sep-2002  provos branches: 1.3.6; 1.3.14;
remove trailing \n in panic(). approved perry.
 1.2  06-Jun-2002  martin Follow changes in libsa/stand.h: exit(void) -> exit(int) (one in a #if
0 block), to make it compile again.
 1.1  20-Aug-2000  mrg branches: 1.1.2; 1.1.4; 1.1.8; 1.1.12; 1.1.20;
move ofwboot & bootblk here; add a Makefile to build ofwboot.net
 1.1.20.1  15-Jul-2002  gehenna catch up with -current.

 1.1.8.2  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
 1.1.8.1  23-Jun-2002  jdolecek catch up with -current on kqueue branch
 1.1.4.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
 1.1.4.1  20-Aug-2000  bouyer file Locore.c was added on branch thorpej_scsipi on 2000-11-20 20:25:50 +0000
 1.1.2.2  26-Aug-2000  mrg move these from arch/sparc64/stand; approved by thorpej.
