ZorroII is at the moment not supported and there is a small problem

The changes is to allow some limited mixer manipulation through

This rendered 4 methods in audio_hw_if unused so garbage collect these.
This will be used by certain SCSI drivers to limit the length of DMA transfers
when the serial port is running at higher speeds. GVP and Phase5 DMA
interfers significantly with CPU execution, and significantly increases
receive buffer overruns (silo overflow). Reducing the DMA transfer length
can reduce the overruns.
NOTE: due to hardware requirement of the AGA chipset, the framebuffer width
has to be a multiple of 64 bits. An 800x600 display will use a memory width
of 832 bits, which the current X server can't handle. To get a usable
display, the width needs to be 832 or 768.

- Improve the error checking in audio.c.

- changes for the grfconfig interface:

- Only print doublescan and interlace flags. Horizontal/vertical sync
polarities are not yet supported and sync-on-green will never be
supported.
- Remove gv->{hblank_stop,vblank_stop} and use the other grfvideo_mode
values to set ba->data.
- Add gv->disp_flags to select interlace.
- Not yet supported are: doublescan, sync-on-green and the horizontal/vertical
sync polarity.
This makes it possible to use xfree values for grfconfig.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.

- Memorysizedetction for 1MB Bords
- Clockdoubling for PicassoIV and PiccoloSD64

with a gfxmode >80Mhz or you get a broken mousepointer.

configuration. This way, the delay loop is calibrated before graphics and
serial hardware is touched.
This change should smooth pr 2890 by Thorsten Frueauf (also privately
reported by Laurent Badoukh). While the real problem with those is the
paranoically high delay() calls in the grf_cl initialization, it was made
even more visible by the miscalibrated (to the save side) new style delay
loop.
making me think that the Blizzard-IV and the Blizzard-2060 scsi
options have nearly identical DMA engines (just with a different
address offset). Alas, this isn't true.
Herewith I replace the "bznsc" (all-new-Blizzard-models) driver with the
"bztzsc" (Blizzard Two Zero).
drisavar.h pretends to provide a few bus.h macros, hardwired to
that chip.
This should eventually be replaced by attachment code for the normal
com.c driver, once that one is split up into chip core driver and
attachment code, and once we have busxxx macros in NetBSD/Amiga.
Earlier, we re-complained about excessive token losses about once a minute.
However, on small ARCnet networks, the token will also be lost if only one
station (us) is active (ifconfig'd down interfaces don't take place in the
token exchange), and our syslog would be filled with repeated messages about
this condition.
Our new code only complains once, starts a timeout() each time a token
regeneration is reported by the chip, and generates a log message about
the regenerated token if it was stable for 15 seconds.

This fixes hangups due to spurious rx interupts.

I've included a workaround for 2 of the CPU bugs in chips with Masks

the CIA.
- builtin SCSI interface (yet another instance of siop)
- CIA timer.
- Zorro II devices which don't do DMA (don't get mapped to Zorro II

- Real Time Clock.
