warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Use -Wno-error=address-of-packed-member for a number of more boot
loaders.

Fix ofwboot to deal with larger kernels. Rather than loading at
0x6?0000, load at 0xe00000. This gives us room for around 13 MB of
kernel, as opposed to the current 5 MB (0x600000 - 0x100000).

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.

minor cosmetic tweaks:
- put \r\n before OF_open message
- use '0' + i % 10 instead of 'A' + i to print the read block number

Fixes from Bill Studenmund and Allen Briggs:
- setup a 32KB (+32byte) stack, instead of 4KB stack
- cache flush: use _start instead of 0x4000, and flush 2k instead of 1k

Features (by me):
- implement:
OF_write() (and grab "stdout" from "/chosen")
putstrn(s,n) using OF_write(); write string s of n bytes long
putstr(s); write fixed-sized string s
putc(c); write char c
- add some useful messages which output the status of loading the
stage 2 bootstrap (which is usually ofwboot)

This code now works on Bill's Beige G3!

Adjust how we set up our stack. According to the ABI, we store the
return pc address at (r1). So don't initialize r1 to be outside our

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

Fix ofwboot to deal with larger kernels. Rather than loading at
0x6?0000, load at 0xe00000. This gives us room for around 13 MB of
kernel, as opposed to the current 5 MB (0x600000 - 0x100000).

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.

revert previous. -fwritable-strings is not needed now that the ld script
does TRT.

add -fwritable-strings to DBG, so that gcc doesn't generate a ".rodata" section.
I believe this fixes PR port-macppc/23206 and the "ofwboot.xcf issues" reported
on the lists since november.

Convert fixcoff into a true host tool by making it under tools.

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Re-add own alloc(). Recent issues with kernels randomly dying on boot
are related to using libsa's alloc(). Problems go away with this alloc().

The problem is that the libsa alloc() assumes we can grab memory off
the end of the program. That assumption doesn't work for us. It's
much better to use the alloc() we were using as it calls OF_claim()
to get memory.

avoid hardcoding MBR_MAGICOFF and MBR_MAGIC.

Pointed out by Christian Groessle on port-macppc, and patch suggested bu

Check in machinery to make ofwboot load at 600000, while ofwboot.elf
and ofwboot.xcf will load at 640000. The idea is that we can now
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.

Remove machine/powerpc links on clean as well.

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
argument gets passed wrongly.
This should fix a bug reported by Martin J. Laubach on port-macppc, and
was fixed two weeks ago in NetBSD/ofppc.

branches: 1.11.6;
avoid hardcoding MBR_MAGICOFF and MBR_MAGIC.

LABELSECTOR is redefined to be 0 on macppc, so it is not usable for MBR
disk label offset. use hardcoded "1" for now, i guess we need a new #define
in sys/disklabel_mbr.h. fixes ofwboot to boot kernel off from MBR-formatted
disk.

Add ustarfs ops.

- 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
the inputs and outputs, rather than using variadic arguments. This
makes it much easier to use OF_call_method() when the format of the
arguments passed to a given method are determined at run-time
(due to e.g. #address-cells).
- Properly inform OpenFirmware where the kernel is loaded by using
"claim" on /chosen/memory and, if running in virtual-mode, using
"claim" on /chosen/mmu to reserve the VA, and "map" on /chosen/mmu
to enter the translation. (The kernel is still always mapped VA==PA.)
