Because the IBM firmware doesn't like the real note section that ld

at the text section. This works, because at the top of the text section,
there is a note hacked in, which was required for the 7044.

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!).

Use <lib/libkern/libkern.h> for str*() prototypes instead of the userland
header <string.h>.

Clean up the NetBSD/ofppc boot loader:
- Garbage collect some cruft that doesn't apply to the ofppc port.
- Make our OFW-friendly alloc.c more like the libsa alloc.c
- Generally reduce some differences where we can between this
boot loader and the NetBSD/macppc boot loader.
- Use libsa's loadfile().
- Fix DDB symbol loading -- Add a magic number after the args string
so the kernel knows the symbols are there, provide both ssym and
esym, and make sure all these values are aligned to a 4-byte boundary.
- Add support for MS-DOS file systems.

Clean up #include paths.
Copy prom2boot() from kernel source.
rename _rtt() to OF_exit(), and add a _rtt() that calls it.

New OpenFirmware boot code for NetBSD/powerpc, based on Wolfgang's original
NetBSD/powerpc boot program. Highligts:
- Rearrange a bit so that we can sanely add boot programs for
non-OpenFirmware systems.
- Add support for loading compressed kernels (for booting from
1.44M floppies).
- Add support for loading Elf kernels (Elf is the new standard format
for NetBSD/powerpc). (XXX Don't load symbols right now - the code
to do it is there, but I don't particularly like how space for the
symbol table is allocated; I will revisit this soon'ish).

Added support for RDB partitions.
Moved MBR parition code out of ofdev.c into mbr.c.
Tested on Pegasos2 (RDB and MBR) and RS6000.

A stack size of 8K is too small for a block buffer of 65536 bytes.
Increased the stack size to 128K. This makes ofwboot work with FirmWorks
OpenFirmware systems again (tested with Motorola PowerStack II).

Add support to ofwboot for booting on the 7046-B50. Also likely to work
on the 7043-150. The B50 wants not only a note at the head of the
binary, like the 7044 did, but it also wants a PHDR that points at it.
Because the IBM firmware doesn't like the real note section that ld
generates (it puts it at the end of the file), we instead point PT_NOTE
at the text section. This works, because at the top of the text section,
there is a note hacked in, which was required for the 7044.

Also, change the mode from virtual mode to real mode in the note, because
the B50 hangs if you load it in virtual. Tested to work on a B50, 7044,
and Pegasos2.

Yay IBM.

branches: 1.1.2; 1.1.4;
Changes to the ofppc ofwboot to make it boot on an IBM CHRP RS/6000.
Tested on a pegasos II and a 7044-270. Also, switch away from the hacked

Add padding to align the rodata section. This fixes a strange bug

Add code to autodetect a 64bit cpu, and attempt to load a different set

verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro
