First cut at x68k network bootloader via NE2000 on Neptune-X and Nereid.
Written by isaki@ back in 2003 based on x86's NE2000 netboot, and
misc debug and improvements by tsutsui@ and Y.Sugahara.

Tested on XM6i (emulating Nereid Ethernet) and X68030 + Neptune-X by me,
also on X68030 + Nereid and X68000 PRO-II + Xellent30 + Nereid by isaki@.

Note:
- X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid,
so this network bootloader needs to be loaded from floppy or harddisk.
- Currently netboot support is not merged into the secondary Multi-boot
(/usr/mdec/boot) due to size restriction.
- Primary loaders assumes that the secondary bootloader name is /boot,
so /usr/mdec/netboot needs to be installed as /boot into the target
bootstrap device.

Fix "Error occurs, please reset" boot problem on
X68030 + 060turbo in 060 mode, found on NetBSD booth
at OSC 2011 Hiroshima:

- use -D__daddr_t=int32_t for all bootloader files
to avoid 64 bit ops in FFS
- explicitly specify -m68020-60 to avoid 64 bit mulsl/mulul
instructions which need to be handled by 060SP emulation
but not available in 060turbo IPL ROM
(LFS still has uint64_t members even with 32bit daddr_t)

The problem was investigated (at least 1.6.2 bootloaders worked)
by Yasushi Oshima at OSC booth, and fixes have been confirmed
by Y.Sugahara on his 060turbo. Thanks everyone!

- add 'ls' op to struct fs_ops to support ls command on each fs,

in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.

Add SCSI host adaptor selector to "boot" command of /boot.
By this function, /boot which booted from non-SCSI

Now, single /boot can load kernel of all supported filesystems
of all supported boot devices.

---
New "boot" command's syntax is: boot [hostadaptor@][dev:][file]

If you booted from SCSI, hostadaptor is already set (from IOCS)
and you can omit hostadaptor in this case. You can type like
"boot sd0a:netbsd" as before.

If you booted from floppy (hostadaptor is not set) and want to
load the SCSI kernel (hostadaptor is needed), you have to select
your hostadaptor in boot command, like "boot spc0@sd0a:netbsd".

Note:
- X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid,
so this network bootloader needs to be loaded from floppy or harddisk.
- Currently netboot support is not merged into the secondary Multi-boot
(/usr/mdec/boot) due to size restriction.
- Primary loaders assumes that the secondary bootloader name is /boot,
so /usr/mdec/netboot needs to be installed as /boot into the target

Check whether the text+data+bss doesn't reach 0x6000 where secondary

Use ASSERT() in ldscript to check first_kbyte (etc) restrictions,
rather than complicated shell expressions in Makefile.

Change primary bootloader's load address from 0x0f0000 to 0x003000.
- Moving addresses closer eliminates bunch of this linker errors:
in function `entry0':
relocation truncated to fit: R_68K_16 against `edata'+ffffffffffff8000
:
- By this change, harmful -noinhibit-exec option can also be removed.
Finally, we can break the builds when assemble error occurs!
- Load address of secondary is 0x6000, so that this change limits
text+data+bss 12KB or less. Current actual size is 5~7KB.
I think it should be fine.
- cd9660 can have up to 30KB text+data in its bootarea. Even in this
case, this change limits text+data+bss 12KB or less (currently, it's
about 6KB). However, I take breaking the builds on errors rather than
future size limitation.

Fix "Error occurs, please reset" boot problem on
X68030 + 060turbo in 060 mode, found on NetBSD booth
at OSC 2011 Hiroshima:

- use -D__daddr_t=int32_t for all bootloader files
to avoid 64 bit ops in FFS
- explicitly specify -m68020-60 to avoid 64 bit mulsl/mulul
instructions which need to be handled by 060SP emulation
but not available in 060turbo IPL ROM
(LFS still has uint64_t members even with 32bit daddr_t)

The problem was investigated (at least 1.6.2 bootloaders worked)
by Yasushi Oshima at OSC booth, and fixes have been confirmed
by Y.Sugahara on his 060turbo. Thanks everyone!

Should also be pulled up to netbsd-5.

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

from UFS2 to UFS2ea and vice-versa (both of which delete all existing extended
attributes in the process).

Specify default SCSI inquiry size (36 bytes) on IOCS_S_INQUIRY() command.

X680x0 SCSI IOCS stalls if SCSI device doesn't return inquiry data
of specified allocation length size on the INQUIRY command,
and it causes hangup on the XM6 based emulators that return only
upto 36 byte inquiry data on SCSI disk emulation.

Many real SCSI-2 hard drives seem to support >100 byte inquiry data,
but at least there is a harddisk that returns only supported inquiry
data size and quits transfer.

The bootloader checks only the device type and there is no reason
to read 100 bytes that includes vender specific data.

First cut at x68k network bootloader via NE2000 on Neptune-X and Nereid.
Written by isaki@ back in 2003 based on x86's NE2000 netboot, and
misc debug and improvements by tsutsui@ and Y.Sugahara.

Tested on XM6i (emulating Nereid Ethernet) and X68030 + Neptune-X by me,
also on X68030 + Nereid and X68000 PRO-II + Xellent30 + Nereid by isaki@.

Note:
- X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid,
so this network bootloader needs to be loaded from floppy or harddisk.
- Currently netboot support is not merged into the secondary Multi-boot
(/usr/mdec/boot) due to size restriction.
- Primary loaders assumes that the secondary bootloader name is /boot,
so /usr/mdec/netboot needs to be installed as /boot into the target
bootstrap device.

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

replace it with real fs ops like readdir if it's really worth

Fix "Error occurs, please reset" boot problem on
X68030 + 060turbo in 060 mode, found on NetBSD booth
at OSC 2011 Hiroshima:

- use -D__daddr_t=int32_t for all bootloader files
to avoid 64 bit ops in FFS
- explicitly specify -m68020-60 to avoid 64 bit mulsl/mulul
instructions which need to be handled by 060SP emulation
but not available in 060turbo IPL ROM
(LFS still has uint64_t members even with 32bit daddr_t)

by Yasushi Oshima at OSC booth, and fixes have been confirmed
by Y.Sugahara on his 060turbo. Thanks everyone!

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.

branches: 1.20.8; 1.20.10; 1.20.14;
Remove _ZLIB_PRIVATE that should have been removed 10 years ago.

Adapt to use of $S/../common/dist/zlib.

branches: 1.18.2;
Make this build again by using ${S}/../common/lib/libc/Makefile.inc,
after the libc/libkern consolidation.

merge ktrace-lwp.

branches: 1.16.16;
Add memmove.c, needed by new ufs.c.

branches: 1.15.2;
Make it compilable.

Update for LFSv2 support. Ports that have "bootxx_lfs"-style
bootblocks currently only support LFSv2, but the second level
"boot" program supports both LFS versions.

- sys/lib/libsa/ufs_ls.c rev 1.3 needs strrchr.
- sort.

Make it compilable with 64bit daddr_t.

libsa/Makefile: Fix rules to create symlinks on read-only source tree.
{boot,libsa,mboot}/Makefile, Makefile.booters:
move that common rule to Makefile.booters

libsa for the new bootloader of x68k port.

First cut at x68k network bootloader via NE2000 on Neptune-X and Nereid.
Written by isaki@ back in 2003 based on x86's NE2000 netboot, and
misc debug and improvements by tsutsui@ and Y.Sugahara.

Tested on XM6i (emulating Nereid Ethernet) and X68030 + Neptune-X by me,
also on X68030 + Nereid and X68000 PRO-II + Xellent30 + Nereid by isaki@.

Note:
- X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid,
so this network bootloader needs to be loaded from floppy or harddisk.
- Currently netboot support is not merged into the secondary Multi-boot
(/usr/mdec/boot) due to size restriction.
- Primary loaders assumes that the secondary bootloader name is /boot,
so /usr/mdec/netboot needs to be installed as /boot into the target
bootstrap device.
