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.

Convert netwinder to generic TODR. Committed after total lack of feedback
(or even acknowledgement of receipt) from anyone on port-netwinder, so it
is untested. (Compiles though.)

don't need md timing functions for joystick anymore

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

Rename dsrtc to ds1687rtc to avoid conflicting with the MI i2c
ds1307 driver.

Hi Jason.

pciide_machdep.c depends on pciide_common, not pciide.
Pointed out and fix tested by Marc Recht.

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

* Move the mii_bitbang attribute into dev/mii/files.mii
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.

Remove obsolete tests of "netwinder" and "footbridge".

Remove options NETWINDER and FOOTBRIDGE; nothing tests for them.

Update for death of arm32.

Reduce the massive code duplication regarding joy(4). Split it into
MI and MD parts, and make ISA/ISAPNP/PCI joy(4) attachments MI.

- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

Move the interrupt-related file declarations into port-specific
config descriptions so that each port choose whether or not to
use it.

The ARM, Ltd. floating point emulator has moved to arch/arm.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.15.6;
Switch netwinder to use a common conf.c for the arm ports.

Move the generic arm32 files into arm/arm32 from arm32/arm32, tested kernel builds on cats and riscpc.

branches: 1.13.2;
Remove defopt EBSA285.
Move the files from footbridge that are cats specific.
Remove EBSA285 kernel as people should be able to use the generic cats kernel for EBSA285 systems.

Merge arm32/dev/bus_space_notimpl.S and hpcarm/hpcarm/bus_space_notimpl.S
into arm/arm/bus_space_notimpl.S. They were identical anyway.

This file has no excuse for being in assembler, but I'll leave that for another
day.

Move netwinder_machdep.c to files.netwinder. Eliminate opt_netwinder.h and
use #ifdef netwinder insead. XXX ebsa285_machdep.c should move to the cats
directory and files.cats

Move defopt FOOTBRIDGE to where it really should be in files.footbridge, which is where I should have left it.

Defopt FOOTBRIDGE.

Move towards common Makefile.arm
Add a netwinder/autoconf.c

Move blockio.S from sys/arch/arm32/arm32 to sys/arch/arm/arm, since I want to
start using it on arm26.

hpcarm gets to keep its own version, since it's not identical and I haven't
got an hpcarm box to test.

Add a files.footbridge for inclusion by cats and netwinder. This is to make moving of the footbridge dir easier (when it eventually moves from arm32)

Also remove EBSA285 defopt from the netwinder file as the netwinder isn't an eval board.

The arch/arm32/kshell code was removed three years ago. Kill references to it.

Move "defopt PMAP_DEBUG" into files.arm, since it's used by code in arch/arm.

Move cpufunc stuff from arm32/arm32 to arm/arm. The only change involved is
to add recognition of the SA-1100 and SA-1110 for compatibility with hpcarm
(which is now using this code as well).

More changes to get the netwinder to multiuser. Hack the initarm code
to reserve the first 2MB for the kernel. Use the netwinder specific
files. Add pci_attach_hook for init the pci devices. Add and alternate
id for the PCI ISA bridge.

A minimum amount to get netwinder support
