Currently the DRQ IRQ is updated every time DMA data is sent/received which
is both inefficient and causes excessive logging of the DRQ state. Add a
new drq_state bool that only updates the DRQ IRQ if its state changes.
This commit adds the new drq_state bool to the migration state: since the
version number has already been increased earlier in the series, there is
no need to repeat it again here. The DRQ IRQ is (currently) only used for
PDMA transfers which already have a migration break in this series so
there are no problems setting its value post-load.

The IRQ represented by irq_data is actually the DRQ (DMA request) line so rename
it accordingly.

According to the datasheet the previous ESP command remains in the ESP_CMD
register, which caused a problem when consecutive TI commands were issued as
it becomes impossible for the state machine to know when the first TI
command finishes.
This was the original reason for introducing the ti_cmd field which kept
track of the last written command for this purpose. However closer reading
of the datasheet shows that a TI command that terminates due to a change of
SCSI target phase resets the ESP_CMD register to zero which solves this
problem.
Now that this has been fixed in the previous commit, remove the unneeded
ti_cmd field and access the ESP_CMD register directly instead. Bump the
vmstate_esp version to indicate that the ti_cmd field is no longer included.

target/hppa: Enhancements and fixes
Some enhancements and fixes for the hppa target.
The major change is, that this patchset adds a new SeaBIOS-hppa firmware
which is built as 32- and 64-bit firmware.
The new 64-bit firmware is necessary to fully support 64-bit operating systems
(HP-UX, Linux, NetBSD,...).

The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode.
Hard fail means the system bus will send an HPMC (=crash) to the
processor, soft fail means the system bus will ignore timeouts of
MMIO-reads or MMIO-writes and return -1ULL.
The HF mode is controlled by a bit in the status register and is usually
programmed by the OS. Return the corresponing values based on the current
value of that bit.

This regressed qemu-system-xtensa:
TEST test_load_store on xtensa
qemu-system-xtensa: Some ROM regions are overlapping
These ROM regions might have been loaded by direct user request or by default.
They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory.
Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses.
The following two regions overlap (in the memory address space):
test_load_store ELF program header segment 1 (addresses 0x0000000000001000 - 0x0000000000001f26)

usb-storage is for the most part just a wrapper around an internally
created scsi-disk device. It uses DEFINE_BLOCK_PROPERTIES() to offer all
of the usual block device properties to the user, but then only forwards
a few select properties to the internal device while the rest is
silently ignored.
This changes scsi_bus_legacy_add_drive() to accept a whole BlockConf
instead of some individual values inside of it so that usb-storage can
now pass the whole configuration to the internal scsi-disk. This enables
the remaining block device properties, e.g. logical/physical_block_size
or discard_granularity.

The VirtIOBlock::rq field has had the type void * since its introduction
in commit 869a5c6df19a ("Stop VM on error in virtio-blk. (Gleb
Natapov)").
Perhaps this was done to avoid the forward declaration of
VirtIOBlockReq.
Hanna Czenczek <hreitz@redhat.com> pointed out the missing type. Specify
the actual type because there is no need to use void * here.

QEMU initializes preallocated backend memory as the objects are parsed from
the command line. This is not optimal in some cases (e.g. memory spanning
multiple NUMA nodes) because the memory objects are initialized in series.
Allow the initialization to occur in parallel (asynchronously). In order to
ensure optimal thread placement, asynchronous initialization requires prealloc
context threads to be in use.

Create the device only if there is a corresponding NIC config for it.
Remove the explicit check on nd_table[0].used from hw/hppa/machine.c
which (since commit d8a3220005d7) tries to do the same thing.
The lasi_82596 support has been disabled since it was first introduced,
since enable_lasi_lan() has always been zero. This allows the user to
enable it by explicitly requesting a NIC model 'lasi_82596' or just
using the alias 'lasi'. Otherwise, it defaults to a PCI NIC as before.

When instantiating XenBus itself, for each NIC which is configured with
either the model unspecified, or set to to "xen" or "xen-net-device",
create a corresponding xen-net-device for it.
Now we can revert the previous more hackish version which relied on the
platform code explicitly registering the NICs on its own XenBus, having
returned the BusState* from xen_bus_init() itself.
This also fixes the setup for Xen PV guests, which was previously broken
in various ways and never actually managed to peer with the netdev.

This patchset introduces IBM's Flexible Service Interface(FSI).
Time for some fun with inter-processor buses. FSI allows a service
processor access to the internal buses of a host POWER processor to
perform configuration or debugging.
FSI has long existed in POWER processes and so comes with some baggage,
including how it has been integrated into the ASPEED SoC.
Working backwards from the POWER processor, the fundamental pieces of
interest for the implementation are:
1. The Common FRU Access Macro (CFAM), an address space containing
various "engines" that drive accesses on buses internal and external
to the POWER chip. Examples include the SBEFIFO and I2C masters. The
engines hang off of an internal Local Bus (LBUS) which is described
by the CFAM configuration block.
2. The FSI slave: The slave is the terminal point of the FSI bus for
FSI symbols addressed to it. Slaves can be cascaded off of one
another. The slave's configuration registers appear in address space
of the CFAM to which it is attached.
3. The FSI master: A controller in the platform service processor (e.g.
BMC) driving CFAM engine accesses into the POWER chip. At the
hardware level FSI is a bit-based protocol supporting synchronous and
DMA-driven accesses of engines in a CFAM.
4. The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in
POWER processors. This now makes an appearance in the ASPEED SoC due
to tight integration of the FSI master IP with the OPB, mainly the
existence of an MMIO-mapping of the CFAM address straight onto a
sub-region of the OPB address space.
5. An APB-to-OPB bridge enabling access to the OPB from the ARM core in
the AST2600. Hardware limitations prevent the OPB from being directly
mapped into APB, so all accesses are indirect through the bridge.
The implementation appears as following in the qemu device tree:
(qemu) info qtree
bus: main-system-bus
type System
...
dev: aspeed.apb2opb, id ""
gpio-out "sysbus-irq" 1
mmio 000000001e79b000/0000000000001000
bus: opb.1
type opb
dev: fsi.master, id ""
bus: fsi.bus.1
type fsi.bus
dev: cfam.config, id ""
dev: cfam, id ""
bus: fsi.lbus.1
type lbus
dev: scratchpad, id ""
address = 0 (0x0)
bus: opb.0
type opb
dev: fsi.master, id ""
bus: fsi.bus.0
type fsi.bus
dev: cfam.config, id ""
dev: cfam, id ""
bus: fsi.lbus.0
type lbus
dev: scratchpad, id ""
address = 0 (0x0)
The LBUS is modelled to maintain the qdev bus hierarchy and to take
advantage of the object model to automatically generate the CFAM
configuration block. The configuration block presents engines in the
order they are attached to the CFAM's LBUS. Engine implementations
should subclass the LBusDevice and set the 'config' member of
LBusDeviceClass to match the engine's type.
CFAM designs offer a lot of flexibility, for instance it is possible for
a CFAM to be simultaneously driven from multiple FSI links. The modeling
is not so complete; it's assumed that each CFAM is attached to a single
FSI slave (as a consequence the CFAM subclasses the FSI slave).
As for FSI, its symbols and wire-protocol are not modelled at all. This
is not necessary to get FSI off the ground thanks to the mapping of the
CFAM address space onto the OPB address space - the models follow this
directly and map the CFAM memory region into the OPB's memory region.
Future work includes supporting more advanced accesses that drive the
FSI master directly rather than indirectly via the CFAM mapping, which
will require implementing the FSI state machine and methods for each of
the FSI symbols on the slave. Further down the track we can also look at
supporting the bitbanged SoftFSI drivers in Linux by extending the FSI
slave model to resolve sequences of GPIO IRQs into FSI symbols, and
calling the associated symbol method on the slave to map the access onto
the CFAM.
Testing:
Tested by reading cfam config address 0 on rainier machine type.

This is a part of patchset where IBM's Flexible Service Interface is
introduced.
This commit models the FSI master. CFAM is hanging out of FSI master which is a bus controller.
The FSI master: A controller in the platform service processor (e.g.
BMC) driving CFAM engine accesses into the POWER chip. At the
hardware level FSI is a bit-based protocol supporting synchronous and
DMA-driven accesses of engines in a CFAM.

This is a part of patchset where IBM's Flexible Service Interface is
introduced.
The Common FRU Access Macro (CFAM), an address space containing
various "engines" that drive accesses on busses internal and external
to the POWER chip. Examples include the SBEFIFO and I2C masters. The
engines hang off of an internal Local Bus (LBUS) which is described
by the CFAM configuration block.

The FSI slave: The slave is the terminal point of the FSI bus for
FSI symbols addressed to it. Slaves can be cascaded off of one
another. The slave's configuration registers appear in address space
of the CFAM to which it is attached.

The scratchpad provides a set of non-functional registers. The firmware
is free to use them, hardware does not support any special management
support. The scratchpad registers can be read or written from LBUS
slave. The scratch pad is managed under FSI CFAM state.

Aspeed SoCs use a single CPU type (set as AspeedSoCClass::cpu_type).
Convert it to a NULL-terminated array (of a single non-NULL element).
Set MachineClass::valid_cpu_types[] to use the common machine code
to provide hints when the requested CPU is invalid (see commit
e702cbc19e ("machine: Improve is_cpu_type_supported()").
