jakllsch | Add gptmbr from syslinux 4.04, with some local modifications to fit our mbr
build system and to be self contanined.
Also, unlink the old mbr_gpt from the build.

jakllsch | Support booting from GPT-partioned disks on PC-BIOS-compatible systems.
Much of the work in this commit was done by Mike Volokhov during GSoC 2009.

dsl | branches: 1.2.24; 1.2.32;
Add two new versions of the mbr code that directly access a serial port.
'mbr_com0' assumes the BIOS has initialised the baud rate (etc)
'mbr_com0_9600' initialises the rate to 9600
Both have the functionality from 'mbr_ext' (ie they can boot from an
extended partition).
As compiled, the io_address for the serial port is taken from BIOS data.
(this should keep tls@ happy!)

Based on code from sbin/fdisk/mbr_bootsel.

|
| 1.10 | 01-Sep-2004 |
dsl | Remove the functionality added in rev 1.7.
With no menu items the mbr_bootsel code will wait for the timeout (default
10 seconds) and then boot the default device - usually the active partition.
Forcing the 'active' partition was wrong - jmmv has a system which needs
to boot from hd1 where hd0 has no mbr partition info.
I suspect the problem I though rev 1.7 fixed was actually caused by
disklabel copying sector zero of the disk to sector zero of the partition!
Gains another 9 bytes of free space, mbr_bootsel now has 20 free bytes.

dsl | Put the 'mbr has bootselect table' marker into all versions of the mbr code.
Having the table in the 'standard' mbr allows fdisk to write in bootsel
menu items and only ask about updating the mbr code before exit.
Sysinst validates that the mbr code contains the bootselect table for
all the mbr code variants it reads - because it might want to write the table
and doesn't really want to make the validation dependant on what it is
going to do later.
Fixes install/25235, but sysinst needs some changes (like reporting the
failure to write the mbr) before the pr itself is closed.

lukem | branches: 1.5.2;
Move mbr_bootsel from offset 404 to offset 400 in struct mbr_sector to
leave 4 bytes for the Windows NT Drive Serial Number (DSN) at 440-443
(as mbr_sector.mbr_dsn).
Ensure that all the MBR & PBR code reserves space for mbr_sector.mbr_dsn.
Leave the bootsel magic number at 444-445 as mbr_sector.mbr_bootsel_magic
(instead of mbr_sector.mbr_bootsel.mbrbs_magic), but use 0xb5e1 (MBR_BS_MAGIC)
instead of 0xaa55 (MBR_MAGIC) to indicate that this change has occurred.
Rework MBR_BS_NEWMBR to mean "mbr_bootsel has moved to 400".
Modify fdisk(8) to automatically relocate the mbr_bootsel from 404 to 400
if mbr_bootsel_magic is the old value (0xaa55), and unset MBR_BS_NEWMBR
to flag that new mbr_bootsel code must be used if updating the MBR.
These changes fixes a problem where Windows 2000 or Windows XP would corrupt
the last 3 bytes + NUL of MBR partition 3's bootsel name if the bootsel name
was 5 characters long, replacing bytes 6-9 with the DSN.
Also, by explicitly reserving the space for the DSN we prevent problems in the
future if non bootsel MBR or PBR code had other information at bytes 440-443.

lukem | 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!).

joerg | Drop explicit loop prefix. GAS doesn't care and LLVM doesn't support it.
Drop the need for assembling with GAS. While LLVM is using a suboptimal
encoding of for hard-coded memory writes, it shouldn't affect
functionality. It just wastes three bytes with extra prefixes.

This was added to detect problems when the mbr code gets written into the pbr.
(When the code loops reading the pbr!)
It is also a useful diagnosting that the boot it proceeding normally.

lukem | 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!).

Add two new versions of the mbr code that directly access a serial port.
'mbr_com0' assumes the BIOS has initialised the baud rate (etc)
'mbr_com0_9600' initialises the rate to 9600
Both have the functionality from 'mbr_ext' (ie they can boot from an
extended partition).
As compiled, the io_address for the serial port is taken from BIOS data.
(this should keep tls@ happy!)
