d16c35256c Use generic tty code instead of local copies.
New devicename is ttyz{port}

No callout devices created.

Isn't this driver superseeded by uart(4) anyway ?

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

672c05d49c Preparation commit for the tty cleanups that will follow in the near
future:

rename ttyopen() -> tty_open() and ttyclose() -> tty_close().

We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.

dc08ffec87 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

cdevsw methods for D_TTY drivers and remove the explicit initializations
in various drivers cdevsw structures.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

d42ee4e410 Note that MAJOR_AUTO is now the default if d_maj is not initialized. This
is more robust and prevents the hijacking of /dev/console for the typical
mistake.

Remove unneeded MAJOR_AUTO uses, it is only needed explicitly now if the
driver source has cross-branch compatibility to old releases.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

for retrieving their softc.

c0d676c068 Make this driver work a whole lot better.
- Get the initial mode from the prom settings and don't clobber the mode
  on open.
- Copy output into an internal ring buffer instead of accessing the tty
  outq directly in the interrupt handler.  This fixes a problem where
  garbage would show up in the output stream.
- Reset the console port completely and reprogram all the parameters
  before enabling it.  This fixes seemingly random hangs on startup
  when using a fast interrupt handler.
- Add minimal locking in place of spls.
- Remove dead code and minor cleanups.
