The at24 eeproms are 2 byte devices that return 0xff when they are read
from with a partial (1-byte) address written. This distinction was
found comparing model behavior to real hardware testing.
Tested: `i2ctransfer -f -y 45 w1@85 0 r1` returns 0xff instead of next

Since PDMA reads/writes are driven by the guest, it is possible that migration
can occur whilst a SCSIRequest is still active. Fortunately active SCSIRequests
are already included in the migration stream and restarted post migration but
this still leaves the reference in ESPState uninitialised.
Implement the SCSIBusInfo .load_request callback to obtain a reference to the
currently active SCSIRequest and use it to recreate ESPState current_req
after migration.

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during
initialisation and resolution changes. Whilst the function of many of these
registers is unknown, it is worth the minimal cost of saving these extra values as

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.

The VIA2 on the Q800 machine is not a separate chip as in older Macs but instead
is integrated into the on-board logic. From analysing the SCSI routines in the
MacOS toolbox ROM (and to a lesser extent NetBSD and Linux) the expectation seems
to be that the SCSI_DATA (DRQ) bit is live on the Q800 and not latched.
Fortunately we can use the recently introduced mos6522 last_irq_levels variable
which tracks the edge-triggered state to return the SCSI_DATA (DRQ) bit live to
the guest OS.

To detect edge-triggered IRQs it is necessary to store the last state of each
IRQ in a last_irq_levels bitmap.
Note: this is a migration break for machines which use mos6522 instances which
are g3beige/mac99 (PPC) and q800 (m68k).

This displays detailed information about the device registers and timers to aid
debugging problems with timers and interrupts.
Currently the QAPI generators for HumanReadableText don't work correctly if
used in qapi/target-misc.json when a non-specified target is built, so for
now manually add a hmp_info_via() wrapper until direct support for per-device
HMP/QMP commands is implemented.

This helps to follow how the guest is programming the mos6522 when debugging.

Now that the mos6522 IRQs are managed using standard qdev gpios these methods
are no longer required.

For historical reasons each mos6522 instance implements its own setting and
update of the IFR flag bits using methods exposed by MOS6522DeviceClass. As
of today this is no longer required, and it is now possible to implement
the mos6522 IRQs as standard qdev gpios.
Switch over to use qdev gpios for the mos6522 device and update all instances
accordingly.
