f18a288632 q800: reimplement mac-io region aliasing using IO memory region
The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".

Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.

281ac13ece m68k: write bootinfo as rom section and re-randomize on reboot
Rather than poking directly into RAM, add the bootinfo block as a proper
ROM, so that it's restored when rebooting the system. This way, if the
guest corrupts any of the bootinfo items, but then tries to reboot,
it'll still be restored back to normal as expected.

Then, since the RNG seed needs to be fresh on each boot, regenerate the
RNG seed in the ROM when reseting the CPU.

Following a change on the kernel side (see link), pass BI_RNG_SEED
instead of BI_VIRT_RNG_SEED. This should have no impact on
compatibility, as there will simply be no effect if it's an old kernel,
which is how things have always been. We then use this as an opportunity
to add this to q800, since now we can, which is a nice improvement.

b793b4ef8c mos6522: implement edge-triggering for CA1/2 and CB1/2 control line IRQs
The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.

To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus
and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as
confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

3ea74abe2d q800: add NMI handler
This allows the programmer's switch to be triggered via the monitor for debugging
purposes. Since the CPU level 7 interrupt is level-triggered, use a timer to hold
the NMI active for 100ms before releasing it again.

c7710c1ebf q800: wire up remaining IRQs in classic mode
Explicitly wire up the remaining IRQs in classic mode to enable the use of
g_assert_not_reached() in the default case to detect any unexpected IRQs.

Add a comment explaining the IRQ routing differences in A/UX mode based
upon the comments in NetBSD (also noting that at least A/UX 3.0.1 still
uses classic mode).

f7c6e12e24 q800: route SONIC on-board Ethernet IRQ via nubus IRQ 9 in classic mode
When the hardware is operating in classic mode the SONIC on-board Ethernet IRQ is
routed to nubus IRQ 9 instead of directly to the CPU at level 3. This does not
affect the framebuffer which although it exists in slot 9, has its own
dedicated IRQ on the Quadra 800 hardware.

39950b16ec q800: move VIA1 IRQ from level 1 to level 6
On a Quadra 800 machine Linux sets via_alt_mapping to 1 and clears port B bit 6 to
ensure that the VIA1 IRQ is delivered at level 6 rather than level 1. Even though
QEMU doesn't yet emulate this behaviour, Linux still installs the VIA1 level 1 IRQ
handler regardless of the value of via_alt_mapping which is why the kernel has been
able to boot until now.

efd0c37edc q800: wire macfb IRQ to separate video interrupt on VIA2
Whilst the in-built Quadra 800 framebuffer exists within the Nubus address
space for slot 9, it has its own dedicated interrupt on VIA2. Force the
macfb device to occupy slot 9 in the q800 machine and wire its IRQ to the
separate video interrupt since this is what is expected by the MacOS
interrupt handler.

df8abbbadf macfb: add common monitor modes supported by the MacOS toolbox ROM
The monitor modes table is found by experimenting with the Monitors Control
Panel in MacOS and analysing the reads/writes. From this it can be found that
the mode is controlled by writes to the DAFB_MODE_CTRL1 and DAFB_MODE_CTRL2
registers.

Implement the first block of DAFB registers as a register array including the
existing sense register, the newly discovered control registers above, and also
the DAFB_MODE_VADDR1 and DAFB_MODE_VADDR2 registers which are used by NetBSD to
determine the current video mode.

These experiments also show that the offset of the start of video RAM and the
stride can change depending upon the monitor mode, so update macfb_draw_graphic()
and both the BI_MAC_VADDR and BI_MAC_VROW bootinfo for the q800 machine
accordingly.

Finally update macfb_common_realize() so that only the resolution and depth
supported by the display type can be specified on the command line, and add an
error hint showing the list of supported resolutions and depths if the user tries
to specify an invalid display mode.

4317c51861 macfb: add qdev property to specify display type
Since the available resolutions and colour depths are determined by the attached
display type, add a qdev property to allow the display type to be specified.

The main resolutions of interest are high resolution 1152x870 with 8-bit colour
and SVGA resolution up to 800x600 with 24-bit colour so update the q800 machine
to allow high resolution mode if specified and otherwise fall back to SVGA.
