- Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
atkbdc(4) and its children were moved to the new location in preparation
for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
order to not further scatter them over the whole tree which would have
been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
reason for the repo-copies was that some of the sources were misfiled,
e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
but are shareable between different atkbdc(4) bus front-ends into
atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
atkbdc(4). PS/2 controllers and input devices are used on a couple of
Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
the board it's either the only on-board mean to connect a keyboard and
mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
without isa(4) (e.g. for EBus-only machines). This ISA-specific part
isn't separated into its own source file, yet, as it requires more work
than was feasible for 6.0 in order to do it in a clean way. Actually
philip@ is working on a rewrite of psm(4) so a more comprehensive
clean-up and separation of hardware dependent and independent parts is
expected to happen after 6.0.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

Remove local hacks to set flags now that the device probe does this for us.
Tested on every device except sio_pci and the pc98 fd.c. Perhaps something
similar should be done for the "disabled" hints also.

- Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
see if the device is disabled in the identify routine instead of in the
probe routine. This way if the device is disabled it is never created.

Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled". If this is a big problem, resource_disabled() can always be
changed to honor both names.

Use __FBSDID().

Fix some easy, global, lint warnings. In most cases, this means
making some local variables static. In a couple of cases, this means
removing an unused variable.

Yet another turn of workaround for psm/ACPI/PnP BIOS
problems currently experienced in -CURRENT.

This should fix the problem that the PS/2 mouse is detected
twice if the acpi module is not loaded on some systems.

Update the atkbdc, atkbd, and psm drivers to probe/attach
more cleanly and consistently in all APCI, PnP BIOS, and "hint"
cases.

NOTE: this doesn't necessarily solve the problem that the PS/2
mouse is not detected after the recent ACPI update.

Add ACPI attachments.

Hints overhaul:
- Replace some very poorly thought out API hacks that should have been
fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
inconvenient temporary ioconf table from config(). We already had a
fallback to using strings before malloc/vm was running anyway.

Convert more malloc+bzero to malloc+M_ZERO.

Staticize some malloc M_ instances.

Untangle some resource matching loops that were getting on my nerves
and seemed to be getting cut/pasted to places they shouldn't be.

Fixed the type of some ivar access functions. Ivars have type uintptr_t,
not u_long. On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().

Missing pieces of the last commit ;-(

- Properly keep track of I/O port resources.
- Use bus_space_read/write() to access the ports.

Do not add children (atkbd and psm) if they are disabled.

Approved by: jkh

Use config's conditional compilation rather than using #ifdefs that make
modular compilation harder. I'm doing this because people seem to like
cut/pasting examples of bad practices in existing code.

Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

Alter the behavior of sys/kern/subr_bus.c:device_print_child()

- device_print_child() either lets the BUS_PRINT_CHILD
method produce the entire device announcement message or
it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

- Devices are 'on' a bus, not 'at' it.
- If a custom BUS_PRINT_CHILD method does the same thing
as bus_generic_print_child(), use bus_generic_print_child()
- Use device_get_nameunit() instead of both
device_get_name() and device_get_unit()
- All BUS_PRINT_CHILD methods return the number of
characters output.

Allocate the port resource when attaching the keyboard controller,
rather than when the individual child device is attached.

No support for pnp yet.

Use the resource apis to manipulate resources.

Slight reorganization of internal interface in the keyboard controller
driver.

Remove hackish foot protection.. If you ask for an atkbd on an isa bus
rather than on the keyboard controller, you will get it.. (and shoot your
feet)

Move the declaration of the interrupt type from the driver structure
to the BUS_SETUP_INTR call.

Print the child IRQ on it's identification line.

As a temporary anti-foot-shooting measure, don't let the user attach
the atkbd device to isa, as was in the old (and 3.x) GENERIC config.

Update the alpha port to use the new syscons.
