jakllsch | bootxx_cd9660 (cdboot), like bootxx_fat16 (fatboot), is not a traditional
libsa-based program. As such, build bootxx_cd9660 where its source lives.
This has been done by moving bootxx/bootxx_cd9660/Makefile to cdboot/Makefile
and adjusting the relative paths appropriately, so as to minimize binary change.

tsutsui | Build and install bootxx_ext2fs, primary boot for ext2fs.
Ext2fs doesn't have enough free space (it has only 1KB)
to store this primary loader, but we can put it into
an independent small 'boot' partition as NetBSD/hp300 does
if it's really necessary.
It could be a fun project to add smaller pre-primary loader
that loads ~8KB primary loader for ext2fs, but probably it's unlikely
because there is a functional wheel named GRUB for ext2fs.

dholland | Introduce .WAIT into the cleandir rule for blasting the libsa/libkern/etc.
trees, because it can race with the libsa/libkern/etc. makefiles' own
cleandir rules. I think I've found all of the uses of the offending idiom...
Closes PR 43360.

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!).

mrg | add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
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.

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.

manu | Primary bootstrap is now able to read a GPT inside RAIDframe.
Previously, primary bootstrap was able to boot on RAID-1 RAIDframe set
with the limitation that the FFS filesystem had to start at bloc 0 in the
RAID. That allowed inner RAID partitionning with a disklabel, but not with
a GPT.
When booting on a RAID-1 RAIDframe, primary bootstrap now first try a
filesystem at bloc 0 of the RAID as before. On failure, it tries to
read a GPT and load secondary bootstrap from, by priority;
1) the first partition with the bootme attribute set
2) the first partition of type FFS, LFS, CCD or CGD
3) the first partition present in the GPT

boot1.c: remove a comment that's no longer relevant/correct
In r. 1.13, a check of the return value in fd was removed, and a comment
about this ("...so keep going") added. Then in r. 1.19, the fd return
value check was reinstated (as the true underlying errno could be masked
by the fstat() call), so there is no "keep going" happening anymore.

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.

dsl | Change interface between bootxx.S and boot1() - always linked together.
This allows boot1() to change the sector number (of the boot partition)
that bootxx.S passes through to boot2().
This means that boot2() will find the correct partition when boot1()
reads /boot from the 'a' partition instead of the mbr boot partition.
This all happens when you update a system that used a small 'wd0h' partition
to boot a raid1 set to the new bootcode. Deleting /boot from the 'wd0h'
partition will make the new bootcode find /boot and the root filesystem
inside the raid set.

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!).

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 | The reserved space for the BIOS Parameter Block (BPB) only needs to be for
FAT16 (11+51) except when booting from FAT{12,16,32}, which needs FAT32 (11+79).
We still reserve the BPB for non-bootxx_msdos PBR bootblocks because
they may be installed as a floppy boot record (and those need a BPB).
Remove some redundant wording in an error messsage, saving 6 bytes.

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!).

a valid MBR entry for partition 3 (covering the first 15 sectors) into the

dsl | Some systems (esp. those with a Promise IDE controller card) seem to
destroy %dl (drive number) across the 'disk reset' command.
Preserve %dl across that call and all registers across the disk reads.
Reorder the code to remove some long conditional jumps to save space.

when loading from CDROM. Change so we don't care what %cs is.
Adjust code layout so that anyone who feels so inclinded can use this for
the mbr code. Note that mbr slot 0 overlays a data area that must be zero
when this is read from the pbr.

Ext2fs doesn't have enough free space (it has only 1KB)
to store this primary loader, but we can put it into
an independent small 'boot' partition as NetBSD/hp300 does
if it's really necessary.
It could be a fun project to add smaller pre-primary loader
that loads ~8KB primary loader for ext2fs, but probably it's unlikely
because there is a functional wheel named GRUB for ext2fs.

Fix the clang build by setting -z noseparate-code
Merge the OPT_SIZE flags. -Oz is not always producing smaller code that -Os,
so default to -Os for both, and we'll override where needed.
Override these two booters with -Oz for clang since it produces smaller code
here.
x86/dosboot: Allow NULL dereference to fetch command line arguments
DOS command line arguments are provided as struct psp at 0x0000;
see doscommain.c.
Recent versions of gcc and clang are clever enough to optimize code
block involving NULL dereference into ud2 insn.
Sprinkle -fno-delete-null-pointer-checks to doscommain.c to
prevent this behavior.
Note that dosboot.com for netbsd-9 and later was broken due to
this ``over optimization''. gcc 5.5.0 and clang 4.0.0 in netbsd-8
generate correct codes without this workaround.
