a115ab5ba3 hw/i386: Mark devices as little-endian
These devices are only used by the X86 targets, which are only
built as little-endian. Therefore the DEVICE_NATIVE_ENDIAN
definition expand to DEVICE_LITTLE_ENDIAN (besides, the
DEVICE_BIG_ENDIAN case isn't tested). Simplify directly using
DEVICE_LITTLE_ENDIAN.

4daf88c165 hw/misc/ivshmem: Rename ivshmem to ivshmem-pci
Because now there is also an MMIO ivshmem device (ivshmem-flat.c), and

e6c33efed3 hw/misc/ivshmem-flat: Add ivshmem-flat device
Add a new device, ivshmem-flat, which is similar to the ivshmem PCI but
does not require a PCI bus. It's meant to be used on machines like those
with Cortex-M MCUs, which usually lack a PCI/PCIe bus, e.g. lm3s6965evb
and mps2-an385.

The device currently only supports the sysbus bus.

The new device, just like the ivshmem PCI device, supports both peer
notification via hardware interrupts and shared memory.

The device shared memory size can be set using the 'shmem-size' option
and it defaults to 4 MiB, which is the default size of shmem allocated
by the ivshmem server.

ff871d0462 hw/pci-host/gpex: Allow more than 4 legacy IRQs
Some boards such as vmapple don't do real legacy PCI IRQ swizzling.
Instead, they just keep allocating more board IRQ lines for each new
legacy IRQ. Let's support that mode by giving instantiators a new
"nr_irqs" property they can use to support more than 4 legacy IRQ lines.
In this mode, GPEX will export more IRQ lines, one for each device.

7bce8d1272 next-cube: move SCSI 4020/4021 logic from next-pc device to next-scsi device
The SCSI 4020/4021 logic refers to the offset of the SCSI CSRs within the NeXTCube

duplicate MMIO accessors in the next.scr memory region for these registers but
this has now been resolved.

Move the remaining SCSI 4020/4021 logic from the next-pc device to the next-scsi
device, with the exception that the SCSI 4021 register now returns its previous
value like a normal register instead of a hardcoded 0x40 value. This also matches
how the registers are implemented in the Previous emulator.

1f21670ec0 vfio/migration: Rename vfio_devices_all_dirty_tracking()
vfio_devices_all_dirty_tracking() is used to check if dirty page log
sync is needed. However, besides checking the dirty page tracking
status, it also checks the pre_copy_dirty_page_tracking flag.

Rename it to vfio_devices_log_sync_needed() which reflects its purpose
more accurately and makes the code clearer as there are already several
helpers with similar names.

6e9df66e8a vfio/migration: Refactor vfio_devices_all_running_and_mig_active() logic
During DMA unmap with vIOMMU, vfio_devices_all_running_and_mig_active()
is used to check whether a dirty page log sync of the unmapped pages is
required. Such log sync is needed during migration pre-copy phase, and
the current logic detects it by checking if migration is active and if
the VFIO devices are running.

However, recently there has been an effort to simplify the migration
status API and reduce it to a single migration_is_running() function.

To accommodate this, refactor vfio_devices_all_running_and_mig_active()
logic so it won't use migration_is_active(). Do it by simply checking if
dirty tracking has been started using internal VFIO flags.

This should be equivalent to the previous logic as during migration
dirty tracking is active and when the guest is stopped there shouldn't
be DMA unmaps coming from it.

As a side effect, now that migration status is no longer used, DMA unmap
log syncs are untied from migration. This will make calc-dirty-rate more
accurate as now it will also include VFIO dirty pages that were DMA
unmapped.

Also rename the function to properly reflect its new logic and extract
common code from vfio_devices_all_dirty_tracking().
