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
byte

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 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.

properties (see e.g. the modified tests/qemu-iotests/172.out).
Now that the last devices relying on isabus_dev_print() had their IRQ
numbers QOM'ified, the contribution of this function ultimately became
redundant. Remove it.

Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be printed by standard QOM mechanisms. This allows
isabus_dev_print() to be retired eventually.

Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be displayed in HMP:
Before:
(qemu) info qtree
...
dev: mc146818rtc, id ""
gpio-out "" 1
base_year = 0 (0x0)
lost_tick_policy = "discard"
After:
dev: mc146818rtc, id ""
gpio-out "" 1
base_year = 0 (0x0)
irq = 8 (0x8)
lost_tick_policy = "discard"
The reason the IRQ number didn's show up before is that this device does not
call isa_init_irq().

Now that gt64120_register() lost its pic parameter, there is an
opportunity to remove it. gt64120_register() is old style by wrapping
qdev API, and the new style is to use qdev directly. So take the
opportunity and modernize the code.

This is a follow-up on patch "malta: Move PCI interrupt handling from
gt64xxx_pci to piix4". gt64xxx_pci used magic constants, and probably
didn't want to use piix4-specific constants. Now that the interrupt
handing resides in piix4, its constants can be used.

Based on commit e735b55a8c11dd455e31ccd4420e6c9485191d0c:
piix_pci: eliminate PIIX3State::pci_irq_levels
PIIX3State::pci_irq_levels are redundant which is already tracked by
PCIBus layer. So eliminate them.
The IRQ levels in the PCIBus layer are already preserved during
migration. By reusing them and rather than having a redundant implementation
the bug is avoided in the first place.

Add the 'bletchley-bmc' machine type based on the kernel DTS[1] and
hardware schematics available to me. The i2c model is as complete as
the current QEMU models support, but in some cases I substituted devices
that are close enough for present functionality. Strap registers are
kept the same as the AST2600-EVB until I'm able to confirm correct
values with physical hardware.
This has been tested with an openbmc image built from [2] plus a kernel
patch[3] for the SPI flash module.
