arm has no need for procfs

None of the mainbus child devices care about getting a bus_space_tag_t from
its parent, because they know better; so don't bother providing one, which
allows more unused code to go to the Attic.

While there, redo the config machinery for mainbus child devices, to bring
it to our current standards. This also allows them to be disabled in UKC,
should there be a need for this in the future.

Late spring cleaning of the arm code for old dusty bits we do not want to
keep:
- remove bootconfig parameter passing feature (unused).
- unifdef __PROG32 and remove all remains of arm26 code.
- remove ARMFPE support (unused).
- remove support for ARM2, ARM2AS, ARM3, ARM6, ARM7, ARM7TDMI and StrongARM
processor families, and the related silicon bug workarounds (especially
the SA-110 STM^ bug).
- remove cpu_functions no longer necessary after previous removals.
- remove ARM32_DISABLE_ALIGNMENT_FAULTS option (unused).
- make FIQ support conditional on option FIQ (unused, but may be eventually).

Hook up imxgpio(4) to the FDT gpio framework.

ok visa@, jsg@

Change openprom into a pseudo-device, because not all arm platforms
will have it. This is a bit of a hack. Maybe it should attach off
mainbus as a proper fake device, but that would have more tendrils..
checked by jsg

Rework mainbus and implement simplebus to be able to span a tree-like
topology based on device tree information. Introduce a common attach
args structure to be used for all fdt-capable bus devices.

ok jsg@ kettenis@

Remove support for ARM10.

ok jsg@

Remove support for ARM9E. This is another step in the plan to remove
all unused and unmaintained ARM processors from the past.

ok bmercer@ jsg@

Remove support for the XScale 80200. We don't use it, it didn't compile
and the included headers didn't even exist.

ok jsg@

Remove support for IXP425. This is another architecture that is not
used and has probably never been used at all. Some included headers
do not even exist.

ok jsg@

Remove support for StrongARM (SA1) and IXP12x0. Both are ARMv4 and
are not used by any of the arm platforms.

ok jsg@

Remove support for ARM9T (armv4t). Not used by any of the arm platforms.
From Patrick Wildt.

Remove support for ARM8, an old armv4 processor without thumb that was
never supported by any arm port and wouldn't have built due to a missing
cpufunc_asm_arm8.S file.

From Patrick Wildt.

remove obsolete INET kernel option

Remove redundant md memcpy.S and memmove.S lines. The mi config
definitions will find the md .S files for these.

disassem.c only if ddb; ok miod

Drain the bufs after or before we do a bus space operation on ARMv7.

ok miod@

Add a cortex bus which represents the ARM MPCore Complex.
It will attach only to ARM Cortex A9 and A15 SoCs.
The generic interrupt controller and timer will attach to this bus,
later a secondary cache controller can be added.
The base address for those controllers are figured out using
the periphbase register.

ok bmercer@

Switch from pmap to pmap7.

ok bmercer@

Move generic armv7 files into arm's file list.

ok bmercer@

merge cpu_coredump() back to where it belongs, ok drahn miod

compat_13 support died ages ago

arm has no need for procfs

None of the mainbus child devices care about getting a bus_space_tag_t from
its parent, because they know better; so don't bother providing one, which
allows more unused code to go to the Attic.

While there, redo the config machinery for mainbus child devices, to bring
it to our current standards. This also allows them to be disabled in UKC,
should there be a need for this in the future.

Late spring cleaning of the arm code for old dusty bits we do not want to
keep:
- remove bootconfig parameter passing feature (unused).
- unifdef __PROG32 and remove all remains of arm26 code.
- remove ARMFPE support (unused).
- remove support for ARM2, ARM2AS, ARM3, ARM6, ARM7, ARM7TDMI and StrongARM
processor families, and the related silicon bug workarounds (especially
the SA-110 STM^ bug).
- remove cpu_functions no longer necessary after previous removals.
- remove ARM32_DISABLE_ALIGNMENT_FAULTS option (unused).
- make FIQ support conditional on option FIQ (unused, but may be eventually).

Discussed with drahn@ and jasper@ long ago, I was sitting on this commit for
no good reason.

- remove unused/commented COMPAT_LINUX stuff

ok deraadt@

Pieces of arm11 and armv7 support for newer cpus. This is work in progress
and not complete.

add support for arm9e core, taken from NetBSD.
ok drahn@

neccessary -> necessary; from Pierre Riteau

libkern, begone. Move to a new mechanism where config(8)'s "file"
directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.

There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.

Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

Remove commented out defopt goo.

Turn GetCPSR() into an inline get_cpsr(), and remove more dead code.

Orphaned stuff.

More netccitt and netns removals; OK henning, brad, mickey

enable arm optimized in4_cksum

ok drahn@

To allow for MD override of in4_cksum()...

ok deraadt@

Cosmetics...
Mainly remove space between locators parens, replace spaces with tabs
where appropriate and consistently align dependencies.

dont make this dependant on bus_space_generic, that is bogus.
keep the define for compat for now.

Move dev/cons.c to MI conf/files.

ok miod@

Remove the old fetch(9)/store(9) functions, since they are not used in
OpenBSD. This gives us a simpler and faster cpu_switch() as a bonus.

ok drahn@

branches: 1.1.2;
Arm port, NetBSD codebase stripped down, 32bit only support.

Unifdef KGDB.

It doesn't compile und hasn't been working during the last decade.

ok kettenis@, deraadt@

Bring over the changes to mainbus(4) and simplebus(4) from arm64.

Move virtio config from files.pci to files.pci

virtio itself is not PCI, it is a paravirtual bus on top of either PCI
or MMIO (arm). This is the first step of moving the virtio files to
dev/pv. No functional change.

arm kernel changes tested by jsg@ and patrick@
no objections from sf@ mlarkin@

remove unused armv4 and xscale files
ok kettenis@ patrick@

Add an implementation of __aeabi_ldivmode() and __aeabi_uldivmod(); clang
generates calls to these functions when compiling an armv7 kernel.

Code from NetBSD's unified userland+kernel implementation, with lots of
irrelevant (for us) #ifdefs removed.

ok patrick@, guenther@

Use a locator (named "early") to let designated drivers attach before others.

ok patrick@, jsg@

Remove code for Intel 80219/80321 xscale processors used by armish.
Generic xscale support and support for pxa2x0 used by zaurus remains.

Build ofw_pinctrl.o and ofw_gpio.o on armv7. The latters here from the
generic arm files list. There is no point in building it on armish or
zaurus.
