5ff9e59f71 Fix a signedness problem in zstty_cncheckc(): when no character is ready,
-1 should be returned, but it was assigned to an uint8_t (which is
extended to an int to form the return value), causing 255 to be returned
instead.

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.

182a9f7455 Make nokqfilter() return the correct return value.
Ditch the D_KQFILTER flag which was used to prevent calling NULL pointers.

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.

eba43df47a Munge the zs sbus attachment to work with fhc. This is a bit of a hack,
but they would otherwise be almost identical so there's not much point in
splitting it up further.

0faf0e2a30 MacIO frontend for the zs driver.
Many thanks to jake for doing the initial driver and for helping me in making
this work.

a42a7e2f13 Set the termios speed based on the tty speed. This allows consoles to work at
speeds other than TTYDEF_SPEED.

in the prom but no keyboard is plugged in.

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.

a6517875d0 Use bus_space_subregion to add offsets to bus handles instead of doing
it manually.

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.
