PCI BIOS mappings are retained, except if option PCI_REMAP
is specified in the kernel config file.
There is now a list of attach addresses, and the first
address that seems to make some device registers appear
is chosen.

Removed screensavers from syscons, they are now LKM's. This makes it
possible to do some really "interesting" screensavers...
Fixed bug that sometimes caused garbage to appear when leaving
"scroll-lock" history.
Reformattet indentation, it got too deep for a normal 80 pos screen.
Split up in syscons.c & syscons.h for use with the saver-lkm's.
Temporarily removed -s option from vidcontrol, savers should now
be loaded with modload.
briefly over it, and see some serious architectural issues in this stuff.
On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.
Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.

when ttselect() is improved. This requires using an array of tty structs
and not using ttymalloc().
Fix an off by 1 error. Some caclulations seem to be off by a factor
of NCY. NCY defaults to 16, which gives 256 tty structs occupying
0xd000 bytes. The minor number encoding only allows 16 ttys.
Update the types of timeout functions to 2.0.
- Overflow now calculated right
- Close works ok,does not looses tty
- Better overflow handling now the snooping stops
on overflow,but programm notified and can reconnect if
it want to..Default maximal buffer set to 664 K and this
is probably too much..:)))
Utility still to come
New config option "NCR_IOMAPPED" makes the driver use port I/O.
Put back in 53c815 defines, submitted by Mikael Hybsch <micke@dynas.se>.

Really write config space register.
Assign ports starting at 0xbc00.

Users-beware..
It is tested and working for me but probably have some bugs i
didn't noticed so test it and reply...
It can:
look at what's sent to the user from tty device
snoop on pty's,vty's and serial tty's
It (still) can't:
write to tty
see what user types in local echo mode
It is probably bad styled and
very dependant on tty_pty.c,sio.c and syscons.c
I would be really happy if another ppl would make their
changes because i am not sure this is the best snoop
we can have..but it is good..:)))))
so that the interface won't have the effect of blocking other senders
during bulk transfers (i.e. hogging the ethernet). It improves performance
in all of my tests by reducing collisions and I believe it to be a Good
Thing.

definitions taken from the PCI specs. Part of them were typed
in by Wolfgang Stanglmeier, the (at that time unneeded) rest
by Charles Hannum (thanks !).
Display update method changed, now allways write in memory buffer,
then periodically update physical display.
Speed improvements (now > 5 times faster than the old syscons).
History now circular buffer, with changeable size.
History scroll by up/down line, up/down page, home and end.
Backtab proberly implemented.
Now space for 96 function keys, 63 allocated standard, default now
SCO/SYSV compat again as in the old days.
New keyboard definition files ~share/syscons/keymaps/*
Misc fixes for old "hacks" that broke SCO/SYSV compat.
More that I forgot before writing this...
case, software cursor now optional case. Driver must provide
raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored
into cards ROM, and syscons nuke out such features completely
by forcing software cursor. Moreover, software cursor is hard
to distinguish on standouted (or near standouted) fields and
tends to disappearse from the screen.
Set "flags 0x4" to enable software cursor now.
o Cleanup screen savers.
o Don't draw cursor if saver or blinker is active.
o Duplicated code moved to functons.
o Add more checks for blinker in progress, character lost otherwise
when blinker restore old contents.
o Reduce blinking counter to 3, too slow in old variant.
o Fix timeout code in scrn_timer(), old variant can reenter iself,
if action takes too long time.
o Disable visual bell for scroll lock mode, saved screen
becomes overwritted otherwise.

Fix attach so 32 bit cards don't call isa_dmacascade.
Add a workaround for 32 bit chips which incorrectly truncate the
ring buffer size.
Fix a bug where CRC errors were reported as framming errors.
Change copyright to a BSD style one.
Print out the length of the compiled sequencer program.
aic7xxx.seq:
More optimizations. Replace generic bcopy routine with bcopy_3
and bcopy_4 (ie unroll the loops) since these are the only two cases used.
Initialize SIMODE1 and SXFRCTL1 from the kernel in ahc_init instead of
at each selection/reselection since this is expensive and only needs to
be done once. Condense function returns into previous instruction if possible.
Reorder some sections to kill superflous jumps. These optimizations kill
the ~150k/s penalty adding support for Twin/Wide cards was costing since
the last place in the commaon path of execution where we had to do ugly,
convoluted testing for the type of card in the sequencer has gone away.
Next stop tagged queuing and target mode.
Obtained from:
sio.c and sioreg.c changed to allow autodetecting the RB_SERIAL flag
passed by the boot blocks so that the kernel can switch to 'serial
console' mode automagically. 'options COMCONSOLE' can still be specified
to force the kernel to always use the serial port as a console.
CONUNIT and CONADDR can also be specified in the kernel config file
if the user wants to shift the console to a different port.
