Changes:
(1) make isa-bus maintain isa irqs, complain when allocating
already taken irqs.
(2) note that (1) works only for isa devices converted to qdev
already (floppy and ps2/kbd/mouse right now), so more work
is needed to make this really useful.
(3) split floppy init into isa and sysbus versions.
(4) add sysbus->isa bridge & fix -M isapc breakage.

First step cleaning up the drives handling. This one does nothing but
removing drives_table[], still it became seriously big.
drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index. This needs adaption in
*tons* of places all over.
The drives are now maintained as linked list.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

The vga_ram_size argument to machine init functions always has the same
value, and is ignored by many machines (including SPARC32 which has an
obsolete ifdef for VGA_RAM_SIZE).
Remove it and push VGA_RAM_SIZE into vga_int.h.

Now we can safely call AUD_init multiple times we can push it down to
individual audio devices, rather than having to pass it from the board
init.

Failure to initialize the audio subsystem is not handled consistently.
Where it is handled it has guest visible effects, which is wrong.
We already have a "nosound" audio driver as a last resort, so trying to
proceed without an audio backend seems pointless.
Also protect against multiple calls to AUD_init so that this can be
pushed down into individual devices.

Attached patch adds emulation of a SONIC netcard. This card has been used
in MIPS Jazz machines and in some Apple Mac 68K.
Emulation has been done using dp83932 specification, but can be enhanced
(if needed) to also emulate dp83916, dp83934 or dp83936 chipsets.
This has been tested in Linux 2.1, NetBSD 1.6.2 and MS Windows NT/MIPS

At the moment, rc4030 init function is returning some function pointers.
Mark them non-static and define them in header file instead.
Export also a function to read/write DMA memory, it will be required by

All archs have some kind of firmware to load and can be fine with it
already. So there is not much use in enforcing the presence of a disk.
If the system setup requires one, the user will notice it anyway once
the firmware/bios fails to boot from it.

On the MIPS Magnum, the time that is held in the RTC's NVRAM should be
relative to midnight on 1980-01-01. This patch adds an extra parameter
to rtc_init(), allowing different epochs to be used. For the Magnum,
1980 is specified, and for all other machines, 2000 is specified.
I've not modified the handling of the century byte, as with an epoch of
1980 and a year of 2009, one could argue that it should hold either
0, 1, 19 or 20. NT 3.50 on MIPS does not read the century byte.

This patch improves G364 video card emulation (used in MIPS Magnum machine):
- Use memory dirty tracking to not refresh whole screen each time
- Use macros for debugging messages
- Add support for hardware cursor
- Handle Y-panning
- Raise irq at each screen redraw
- Support retrieving of some registers
- Add load/save support
The emulation has been tested in Linux 2.1 and Windows NT 3.5, in
640x480, 800x600, 1024x768 and 1280x1024 resolutions.

Patch 5/7
This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.
This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.
This patch does *not* include any required changes to any device, these
changes come with the following patches.
Patch 6/7
This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;
In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.
Patch 7/7
This patch updates the graphic device code to use the new
graphical_console_init function.
As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.

Attached patch implements DMA support to RC4030 chipset and simplifies
jazz IO part (at 0xf0000000), where registers contain 16 bit values.
Config register has not a clear meaning (only one value is always valid,
and sometimes another one), so use a magic value instead.
The patch also wires DMA transfers for the SCSI adapter in the Jazz
emulation (Mips Magnum 4000 and Acer Pica 61).

Current implementation of memory-mapped i8042 controller is atm
implemented with an interface shift (it_shift) parameter, like most all
memory-mapped devices in Qemu.
However, this isn't suitable for MIPS Magnum, where i8042 controller is at
0x80005000 up to 0x80005fff.
Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real
machine, and found that odd addresses are for status/command register, and
even addresses for data register.
Attached patch implements this behaviour by replacing the it_shift
parameter by a mask one.
Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042
controller at 0x80005060 and 0x80005061.

Introduce a max_cpus per-machine variable, allowing individual boards
to limit it's number of CPUs. Check requested number of CPUs in setup
code and exit if it exceeds the supported number for the machine.
This also renders the static MAX_CPUS check obsolete, so remove this
from vl.c.
