Add PXA25x based Zaurus SL-C700/750/760/860 support.

All porting work was done by TOYOKURA Atsushi, with
several minor adjustments for integration by me and nonaka@.

His SL-C700 first running NetBSD/zaurus was demonstrated on
NetBSD booth at Open Source Canference 2011 Tokyo/Fall:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-tokyofall

Note GENERIC kernel works on SL-C750/760/860 (and C1000/3x00) but for now
SL-C700 requires its own kernel with special KERNEL_BASE_PHYS address
due to zbsdmod.o loader restriction (probably caused its small 32MB RAM).

Mention DKWEDGE_METHOD_TOS in several kernel config files

PR/57889: Ricardo Branco: ext2fs does not have user immutable and append
file flags, only system ones. Restrict those to the superuser. Before
the behavior was controlled by EXT2FS_SYSTEM_FLAGS. Make that behavior the
default.

Adjust _all_ cinclude of *.local files

- Ensure always at end
- Use tab rather than spaces
- Add consistent comment
"Pull in optional local configuration - always at end"

The only functional change is that a local file which tried to
override an existing setting (eg with "no foo") would have failed
in some cases before, but now will work

Ensure GENERIC.local is always at the end of GENERIC

Where a GENERIC config had an existing inclusion of GENERIC.local,
ensure it is always at the end of the file, with a consistent
comment:

# Pull in optional local configuration
cinclude "arch/landisk/conf/GENERIC.local"

This allows GENERIC.local to correctly override all options

(This pass does not affect any GENERIC which did not already have
an include of GENERIC.local)

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:

Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

Fix kernel size overflow caused by addition of ure(4) and PHY drivers.

Modern USB NICs are useful due to availability in the market, although
they cannot exhibit full performance with ohci(4). Also, some of them
support RX/TX offloading, which can be useful even with ohci(4).

Therefore, rather add modern NICs in usbdevices.config.

Instead, remove PHY drivers that cannot be used with zaurus.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Disable BSDLABEL and MBR DKWEDGE methods again since sysinst does not work
with wedges.

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is

the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

Apply WM8731 support patch from TOYOKURA Atsushi, arranged by me.

- SL-C700: work fine
- SL-C750: attach failed
- SL-C860: not tested

branches: 1.11.6;
Add PXA25x based Zaurus SL-C700/750/760/860 support.

All porting work was done by TOYOKURA Atsushi, with
several minor adjustments for integration by me and nonaka@.

His SL-C700 first running NetBSD/zaurus was demonstrated on
NetBSD booth at Open Source Canference 2011 Tokyo/Fall:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-tokyofall

Note GENERIC kernel works on SL-C750/760/860 (and C1000/3x00) but for now
SL-C700 requires its own kernel with special KERNEL_BASE_PHYS address
due to zbsdmod.o loader restriction (probably caused its small 32MB RAM).

Reorganlization zlcd(4) and ztp(4) device attachments from nonaka@:
- ztp depends on zssp so attach ztp at zssp rather than pxaip
- split LCD backlight controls from zlcd(4) into new lcdctl device
to share it among forthcoming SL-C7x0 variants

branches: 1.9.2; 1.9.6;
more support SL-C1000.

branches: 1.8.10;
Added SD/MMC support from OpenBSD.
tested on i386, amd64 at current-users ML by pgoyette@.
tested on zaurus by myself.

Added kloader support.

branches: 1.6.4; 1.6.12; 1.6.18;
Add GPIO pins for USB cable type detection and glue for zusb devices for
config.

branches: 1.5.6;
Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

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.

branches: 1.3.2; 1.3.6;
Added support to detect AC adapter and charge battery.

Apply ldscript fixes for binutils-2.39. See PR 57223.

Drop CTF sections from this size restricted kernel (especially as the
size check is on the total size of the binary, not any content/sections -
is this a bug?)
Compile with -O2 by default (to shrink the kernel to a usable size again
and unbreak the build)

branches: 1.11.18;
Don't need to specify OUTPUT_FORMAT/OUTPUT_ARCH.

.rel/.rela should not be generated in kernels.

According to matt@, .ARM.{extab,exidx} are no longer used.

Simplify this by deciding load address at one place.

Indent with 2 spaces.

Kill trailing whitespaces.

branches: 1.5.6;
Put EHABI exception tables at the end of text.
provide __exidx_start and __exidx_end symbols.

delete eh_frame gunk, which hopefully will make the kernel small enough to boot.

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

branches: 1.11.8;
mark nsmb major obsolete

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

branches: 1.9.6;
Systematize handling of removed drivers.

- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.

Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.

Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)

Remove ISDN from the kernel. It has remained unmaintained for a long time,
is of poor quality, and is now an obstacle to MP-ification. It was removed
ten years ago from FreeBSD for the same reason.

This retires a big user of the mbuf API, and will ease maintenance of the
kernel.

branches: 1.7.16; 1.7.18;
Update device dependency information - the sysmon major device now depends on the sysmon module itself, not on the individual components.

branches: 1.6.12; 1.6.30;

Add an arm/conf/std.arm file which contains common arm options, initially
just options CPU_IN_CKSUM.
