Even though the BLAST command isn't fully implemented in QEMU, the DMA_STAT_BCMBLT
bit should be set after the command has been issued to indicate that the command

This fixes an issue with the DC390 DOS driver which issues the BLAST command as
part of its normal error recovery routine at startup, and otherwise sits in a
tight loop waiting for DMA_STAT_BCMBLT to be set before continuing.

hw/scsi/esp-pci: synchronise setting of DMA_STAT_DONE with ESP completion interrupt

The setting of DMA_STAT_DONE at the end of a DMA transfer can be configured to
generate an interrupt, however the Linux driver manually checks for DMA_STAT_DONE
being set and if it is, considers that a DMA transfer has completed.

If DMA_STAT_DONE is set but the ESP device isn't indicating an interrupt then
the Linux driver considers this to be a spurious interrupt. However this can
occur in QEMU as there is a delay between the end of DMA transfer where
DMA_STAT_DONE is set, and the ESP device raising its completion interrupt.

This appears to be an incorrect assumption in the Linux driver as the ESP and
PCI DMA interrupt sources are separate (and may not be raised exactly
together), however we can work around this by synchronising the setting of
DMA_STAT_DONE at the end of a DMA transfer with the ESP completion interrupt.

In conjunction with the previous commit Linux is now able to correctly boot
from an am53c974 PCI SCSI device on the hppa C3700 machine without emitting
"iget: checksum invalid" and "Spurious irq, sreg=10" errors.

hw/scsi/esp-pci: generate PCI interrupt from separate ESP and PCI sources

The am53c974/dc390 PCI interrupt has two separate sources: the first is from the
internal ESP device, and the second is from the PCI DMA transfer logic.

Update the ESP interrupt handler so that it sets DMA_STAT_SCSIINT rather than
driving the PCI IRQ directly, and introduce a new esp_pci_update_irq() function
to generate the correct PCI IRQ level. In particular this fixes spurious interrupts
being generated by setting DMA_STAT_DONE at the end of a transfer if DMA_CMD_INTE_D
isn't set in the DMA_CMD register.

hw/scsi/esp-pci: use correct address register for PCI DMA transfers

The current code in esp_pci_dma_memory_rw() sets the DMA address to the value
of the DMA_SPA (Starting Physical Address) register which is incorrect: this
means that for each callback from the SCSI layer the DMA address is set back
to the starting address.

In the case where only a single SCSI callback occurs (currently for transfer
lengths < 128kB) this works fine, however for larger transfers the DMA address
wraps back to the initial starting address, corrupting the buffer holding the
data transferred to the guest.

Fix esp_pci_dma_memory_rw() to use the DMA_WAC (Working Address Counter) for
the DMA address which is correctly incremented across multiple SCSI layer
transfers.

scsi: Replace scsi_bus_new() with scsi_bus_init(), scsi_bus_init_named()

The function scsi_bus_new() creates a new SCSI bus; callers can
either pass in a name argument to specify the name of the new bus, or
they can pass in NULL to allow the bus to be given an automatically
generated unique name. Almost all callers want to use the
autogenerated name; the only exception is the virtio-scsi device.

Taking a name argument that should almost always be NULL is an
easy-to-misuse API design -- it encourages callers to think perhaps
they should pass in some standard name like "scsi" or "scsi-bus". We
don't do this anywhere for SCSI, but we do (incorrectly) do it for
other bus types such as i2c.

The function name also implies that it will return a newly allocated
object, when it in fact does in-place allocation. We more commonly
name such functions foo_init(), with foo_new() being the
allocate-and-return variant.

Replace all the scsi_bus_new() callsites with either:
* scsi_bus_init() for the usual case where the caller wants
an autogenerated bus name
* scsi_bus_init_named() for the rare case where the caller
needs to specify the bus name

and document that for the _named() version it's then the caller's
responsibility to think about uniqueness of bus names.

esp: fix setting of ESPState mig_version_id when launching QEMU with -S option

If QEMU is launched with the -S option then the ESPState mig_version_id property
is left unset due to the ordering of the VMState fields in the VMStateDescription
for sysbusespscsi and pciespscsi. If the VM is migrated and restored in this
stopped state, the version tests in the vmstate_esp VMStateDescription and
esp_post_load() become confused causing the migration to fail.

Fix the ordering problem by moving the setting of mig_version_id to a common
esp_pre_save() function which is invoked first by both sysbusespscsi and
pciespscsi rather than at the point where ESPState is itself serialised into the
migration stream.

esp: add vmstate_esp version to embedded ESPState

The QOM object representing ESPState is currently embedded within both the
SYSBUS_ESP and PCI_ESP devices with migration state handled by embedding
vmstate_esp within each device using VMSTATE_STRUCT.

Since the vmstate_esp fields are embedded directly within the migration
stream, the incoming vmstate_esp version_id is lost. The only version information
available is that from vmstate_sysbus_esp_scsi and vmstate_esp_pci_scsi, but
those versions represent their respective devices and not that of the underlying
ESPState.

Resolve this by adding a new version-dependent field in vmstate_sysbus_esp_scsi
and vmstate_esp_pci_scsi which stores the vmstate_esp version_id field within
ESPState to be used to allow migration from older QEMU versions.

Finally bump the vmstate_esp version to 5 to cover the upcoming ESPState changes
within this patch series.
