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.

Bump version - virtio support added

branches: 1.21.2; 1.21.4;
Bump version now that we can load kernels with sizeof(.data)+sizeof(.bss)> 4 MB

branches: 1.20.4; 1.20.6;
Add support for running ofwboot on sun4v. Please note that the kernel on sun4v will be loaded properly but when the kernel takes over it will crash immediately since the kernel is not sun4v ready yet

branches: 1.19.8; 1.19.18; 1.19.22;
Bump version

branches: 1.18.2; 1.18.4;
Properly close the firmware handle before starting the kernel.
This makes netbooting via bge* work.

Make 3 attempts at bootp before trying bootparams which allows slow
bridges a chance to work.
Clear variables when changing bootp/bootparams.
Displayed variables are cleaned up so they don't overflow the right of
the screen.

ok: martin

branches: 1.16.8;
Deal with kernels that have a combined text/data segment. Output a big
warning when booting them.

branches: 1.15.16; 1.15.20; 1.15.22; 1.15.26;
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.

Enable booting from news Solaris ufs partitions.

Bump version

branches: 1.12.8; 1.12.10;
Use the new loadfile() marker MARK_DATA to optimize the loaded kernel
mappings before calling the entry point - change text mappings to read
only and only insert those into the iTLB.
While there remove a few magic constants by information queried from
the firmware.

branches: 1.11.28; 1.11.30; 1.11.36;
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.

branches: 1.10.2;
merge ktrace-lwp.

branches: 1.9.12;
Better support for booting from partitions != a or at the start of the
disk, allow commands like "boot disk:d disk:d/netbsd" to work.
Use the real RF_PROTECTED_SECTORS define instead of a local magic number.
While there, minor cosmetics in diagnostics/output format.

When calculating the allocated symbol table size, round up the section
sizes with ELF_ALIGN().
Fixes PR port-sparc64/25429.

branches: 1.7.6; 1.7.8;
Allow hyphen in kernel names. Bump version.
Should fix PR 13429 and PR 18691.

branches: 1.6.6; 1.6.16;
Handle kernels with data+BSS segments larger than 4MB.

Bump version.

Undo version bump. The sparc ofwboot doesn't use loadfile().

Bump version numbers of all bootloaders that use loadfile/ELF, to account for
my changes to symbol loading. I should probably have done this at the time,
but it's better late than never.

branches: 1.2.2; 1.2.6;
note support for verbose/quiet boot (-v, -q flags)

branches: 1.1.2;
move ofwboot & bootblk here; add a Makefile to build ofwboot.net
