- 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.

Tested on:	i386, sparc64 (AX1105, AXe and AXi boards)

- * I/O access arbitration in `kbdio'
- *
- * The `kbdio' module uses a simplistic convention to arbitrate
- * I/O access to the controller/keyboard/mouse. The convention requires
- * close cooperation of the calling device driver.
- *
- * The device drivers which utilize the `kbdio' module are assumed to
- * have the following set of routines.
- *    a. An interrupt handler (the bottom half of the driver).
- *    b. Timeout routines which may briefly poll the keyboard controller.
- *    c. Routines outside interrupt context (the top half of the driver).
- * They should follow the rules below:
- *    1. The interrupt handler may assume that it always has full access 
- *       to the controller/keyboard/mouse.
- *    2. The other routines must issue `spltty()' if they wish to 
- *       prevent the interrupt handler from accessing 
- *       the controller/keyboard/mouse.
- *    3. The timeout routines and the top half routines of the device driver
- *       arbitrate I/O access by observing the lock flag in `kbdio'.
- *       The flag is manipulated via `kbdc_lock()'; when one wants to
- *       perform I/O, call `kbdc_lock(kbdc, TRUE)' and proceed only if
- *       the call returns with TRUE. Otherwise the caller must back off.
- *       Call `kbdc_lock(kbdc, FALSE)' when necessary I/O operaion
- *       is finished. This mechanism does not prevent the interrupt 
- *       handler from being invoked at any time and carrying out I/O.
- *       Therefore, `spltty()' must be strategically placed in the device
- *       driver code. Also note that the timeout routine may interrupt
- *       `kbdc_lock()' called by the top half of the driver, but this
- *       interruption is OK so long as the timeout routine observes
- *       rule 4 below.
- *    4. The interrupt and timeout routines should not extend I/O operation
- *       across more than one interrupt or timeout; they must complete any
- *       necessary I/O operation within one invocation of the routine.
- *       This means that if the timeout routine acquires the lock flag,
- *       it must reset the flag to FALSE before it returns.

- *  Ported to 386bsd Oct 17, 1992
- *  Sandi Donno, Computer Science, University of Cape Town, South Africa
- *  Please send bug reports to sandi@cs.uct.ac.za
- *
- *  Thanks are also due to Rick Macklem, rick@snowhite.cis.uoguelph.ca -
- *  although I was only partially successful in getting the alpha release
- *  of his "driver for the Logitech and ATI Inport Bus mice for use with
- *  386bsd and the X386 port" to work with my Microsoft mouse, I nevertheless
- *  found his code to be an invaluable reference when porting this driver
- *  to 386bsd.
- *
- *  Further modifications for latest 386BSD+patchkit and port to NetBSD,
- *  Andrew Herbert <andrew@werple.apana.org.au> - 8 June 1993
- *
- *  Cloned from the Microsoft Bus Mouse driver, also by Erik Forsberg, by
- *  Andrew Herbert - 12 June 1993
- *
- *  Modified for PS/2 mouse by Charles Hannum <mycroft@ai.mit.edu>
- *  - 13 June 1993
- *
- *  Modified for PS/2 AUX mouse by Shoji Yuen <yuen@nuie.nagoya-u.ac.jp>
- *  - 24 October 1993
- *
- *  Hardware access routines and probe logic rewritten by
- *  Kazutaka Yokota <yokota@zodiac.mech.utsunomiya-u.ac.jp>
- *  - 3, 14, 22 October 1996.
- *  - 12 November 1996. IOCTLs and rearranging `psmread', `psmioctl'...
- *  - 14, 30 November 1996. Uses `kbdio.c'.
- *  - 13 December 1996. Uses queuing version of `kbdio.c'.
- *  - January/February 1997. Tweaked probe logic for 
- *    HiNote UltraII/Latitude/Armada laptops.
- *  - 30 July 1997. Added APM support.
- *  - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX). 
- *    Improved sync check logic.
- *    Vendor specific support routines.
