Add riscv.

Remove no-op emips stuff.

It seems blindly copied and modified from pmax, but emips bootloader

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

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.

Add installboot(8) support for evbarm (and, in the future, other evb*)
boards that use u-boot. A known board database lists boards and their
respective u-boot packages. u-boot packages are discovered at run-time
(in /usr/pkg/share/u-boot, by default). These packages contain board
database overlays that describe u-boot installation procedure that's
specific for that board.

Support this as a native tool and as a host tool. The native tool
will attempt to determine the running board type using OpenFirmware
calls. Host tool and native tool alike may also specify a board type
directly using the "-o board=xxx option" or have installboot(8) determine
the board type from a device tree blob using "-o dtb=/path/to/board.dtb".
A "-o media=xxx" option is provided for boards that have different u-boot
binaries and/or installation procedures for different media types (e.g.
SDMMC, eMMC, or USB).

This is trivial to extend to other evb* platforms that use u-boot, even if
they don't use FDT for autoconfiguration.

usr.sbin/installboot: Add a command line option (-u) to set U-Boot search paths

Installboot can install U-Boot boot blocks directly into a system
image. Normally, the U-Boot files are searched for in
/usr/pkg/share/u-boot, under the expectation that most people will
build them with pkgsrc. However, it is also possible to set an
environment variable (INSTALLBOOT_UBOOT_PATHS) to a colon-separated
search path to accommodate other situations. This commit adds a
command line option (-u) to set the search path; if present, it
overrides the environment and default.

Another mistake in the ufs2 code - a missing else.

Fix two mistakes done in the UFS2 merge:
o Correct the order of arguments to ffs_read_disk_block; the second one
is blocknumber to read, not the size to be read. This would affect the
UFS2 code, and is thus not much excercised at the moment.
o The offsets in SBLOCKSEARCH are in bytes, but ffs_read_disk_block wants
its location in terms of DEV_BSIZE blocks. Fix this bug in ffs_match().
The latter together with the recent magic number fix to <ufs/ffs/fs.h>
fixes a cross build problem seen when doing a i386->sparc build.

Add cats for printf %llu arguments, for the benefit of LP64 platforms.

With the new UFS2 code, alternative places are searched for a super-block.

- add hardcode_stage2(), which uses -B s2bno and the size of the
provided secondary bootstrap (as an actual file, not as part of the
`filesystem' argument) to provide a sequential list of blocks from s2bno,
each block being the appropriate file system size (from
params->fstype->blocksize)
- add blocksize and needswap run-time parameters to ib_fs

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Installboot can install U-Boot boot blocks directly into a system

Fix typos. Fix link. Use Pa for path.

Add installboot(8) support for evbarm (and, in the future, other evb*)
boards that use u-boot. A known board database lists boards and their
respective u-boot packages. u-boot packages are discovered at run-time
(in /usr/pkg/share/u-boot, by default). These packages contain board
database overlays that describe u-boot installation procedure that's
specific for that board.

Support this as a native tool and as a host tool. The native tool
will attempt to determine the running board type using OpenFirmware
calls. Host tool and native tool alike may also specify a board type
directly using the "-o board=xxx option" or have installboot(8) determine
the board type from a device tree blob using "-o dtb=/path/to/board.dtb".
A "-o media=xxx" option is provided for boards that have different u-boot
binaries and/or installation procedures for different media types (e.g.
SDMMC, eMMC, or USB).

This is trivial to extend to other evb* platforms that use u-boot, even if
they don't use FDT for autoconfiguration.

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.

are hardcoded into the stage1 bootstrap (currently: sparc, sun2)

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

usr.sbin/installboot: Add a command line option (-u) to set U-Boot search paths

Installboot can install U-Boot boot blocks directly into a system

/usr/pkg/share/u-boot, under the expectation that most people will
build them with pkgsrc. However, it is also possible to set an
environment variable (INSTALLBOOT_UBOOT_PATHS) to a colon-separated
search path to accommodate other situations. This commit adds a
command line option (-u) to set the search path; if present, it
overrides the environment and default.

add next68k support to installboot

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

Explicitly pull in <sys/endian.h> #if !defined(HAVE_CONFIG_H).

macros a lot)

Coverty 7449: Change 'return (0)' to 'goto done' so we free(bootstrapbuf)

Move the MD definitions into the MD files, leaving machines.c with just

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

Add installboot(8) support for evbarm (and, in the future, other evb*)
boards that use u-boot. A known board database lists boards and their
respective u-boot packages. u-boot packages are discovered at run-time
(in /usr/pkg/share/u-boot, by default). These packages contain board
database overlays that describe u-boot installation procedure that's
specific for that board.

Support this as a native tool and as a host tool. The native tool
will attempt to determine the running board type using OpenFirmware
calls. Host tool and native tool alike may also specify a board type
directly using the "-o board=xxx option" or have installboot(8) determine
the board type from a device tree blob using "-o dtb=/path/to/board.dtb".
A "-o media=xxx" option is provided for boards that have different u-boot
binaries and/or installation procedures for different media types (e.g.
SDMMC, eMMC, or USB).

This is trivial to extend to other evb* platforms that use u-boot, even if
they don't use FDT for autoconfiguration.

Always read LIF volume/directory from stage1 even on cd9660 stage2 case.

mmap(2) against the bootstrap file in the target cd9660 could fail
because the sector size of ISO9660 is 2048 so each file could be
allocated at an offset not pagesize (4096 or 8192) aligned.

This could fail if stage1 (specified via "primary" arg on command line)
and stage2 (on the target filesystem) files are different, but
in "build.sh iso-image" case they are always identical.

The problem (build failures in auotomated builds for hp300 on Linux)
was reported by Jan-Benedict Glaw.

Should also be pulled up to netbsd-10.

branches: 1.19.2;
Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Invert the flag bits to control module loading: rename
LOADMODULES->NOMODULES and READBOOTCONF->NOBOOTCONF.
This way, the default value (0) wired into old bootxx_* and installed
to file systems remains valid and we avoid problems on partial updates.

On i386/amd64, define two flag bits in the boot parameters which control
whether modules are loaded and whether boot.cfg is evaluated, and
set both to "off" per default in the PXE bootloader.
Extend "installboot" to toggle the bits.
This way, pxeboot works with existing dhcp server setups (and as
described in the manpage) out of the box. Also, boot.cfg reading
involves a stat() call which is horribly inefficient with the
TFTP pseudo file system.

Instead of requiring that the BPB is always the FAT32 one, check the
first three bytes to determine how much of the BPB to preserve.
Supported values:
eb 3c 90 FAT16 BPB
eb 58 90 FAT32 BPB
(anything else) don't preserve any BPB

This is because the BPB is generally only the FAT16 one except in the
bootxx_msdos case, where it's the larger FAT32 one.

Fix compile error on powerpc. Noted by Juergen Hannken-Illjes in private mail.

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!).
