- When starting the boot program, cache a bunch of OFW frequently used
ihandles / phandles, rather than fetching them all the time.
- Change the signature of OF_call_method() to take an array of cells for

- Properly inform OpenFirmware where the kernel is loaded by using
"claim" on /chosen/memory and, if running in virtual-mode, using

When boot up with auto-boot? == true, some systems do not provide stdout
if the normal output is screen.

Open screen explicitly as stdout in this case, both for ofwboot and kernel,
which fixes problems with auto-boot? == true for Mac mini G4:

- messages from ofwboot do not appear
- kernel freeze during early boot stage

Remove vestiges of the syncicache() call originally in powerpc/ofwboot
before rev 1.4. This change makes OF 2.4 machines actually boot, and
it works fine on my OF 2.01 machine. No reports of failures on other
archs.

I expect this change is fine as the original code flushed the just-loaded
ofwboot out of the cache, conditionalized on FIRMWORKSBUGS. In rev.
1.4, the code got in-lined, and changed to actually flush low memory
out of the cache. Since machines kept booting, I expect the firmware
was really flushing the binary out of the cache, so we're fine.

Fix ofwboot to deal with larger kernels. Rather than loading at

No changes to load-base or real-base are needed due to this change,
though machines that needed specific OFW settings before (OF 1.x
and 2.x) this change still need those settings.

Partially revert revision 1.25 -> 1.26 of ofwboot/Makefile & friends.
We do not need to distinguish between where ofwboot and ofwboot.{elf,xcf}
load; they are both fine loading somewhere other than load-base.

Check in machinery to make ofwboot load at 600000, while ofwboot.elf

leave load-base at 600000, and it will work right for all three methods.

The problem is that the file loader and the net loader use load-base
as a scratch area, so if the executable really wants to load there,
the load fails.

This has been lying around in my tree for too long now.

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.

As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).

amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.

* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.

* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.

* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.

* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.

installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)

mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

strategy() should really have an ANSI prototype. Otherwise its daddr_t
