95bc568977 Add new function ttyinitmode() which sets our systemwide default
modes on a tty structure.

Both the ".init" and the current settings are initialized allowing
the function to be used both at attach and open time.

The function takes an argument to decide if echoing should be enabled.
Echoing should not be enabled for regular physical serial ports
unless they are consoles, in which case they should be configured
by ttyconsolemode() instead.

Use the new function throughout.

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.

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.

263444cfbf Change the console interface to pass a "struct consdev *" instead of a
dev_t to the method functions.

The dev_t can still be found at struct consdev *->cn_dev.

Add a void *cn_arg element to struct consdev which the drivers can use
for retrieving their softc.

6bfa8a2ef2 Split this into bus specific front end(s), so that it can be used by ppc.
This abstracts out all the differences I could see between the netbsd
sparc64 and macppc zs drivers.   In particular the offsets of the csr and
data registers are different, so we use a separate bus handle for each and
use bus_space_subregion to add the bus specific offsets.

777cc88b9d - This damnable chip only has 1 status register for both ports, so the bit
positions for the status bits of port a and port b are different.  To
  avoid needing to know which channel the interrupt handler is working on,
  shift the status bits for port a into the port b bit positions, and always
  check the port b status bits.  This fixes using port b, which I neglected
  to test before.
- Remember to update the channel's tty structure from the passed in termios
  in the param routine.
- Minor style.

75db2b5e27 Add a driver for the Zilog 8530 dual uart found in Ultra 1s and Ultra 2s.
With a 1 byte transmit fifo, 3 byte receive fifo, and wierd multiplexed I/O
designed for a Z80 cpu, this chip redefines suckage.

Based on the openbsd and netbsd drivers.  Only really works as a console,
modem support is not complete since I can't test it.
