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.

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.

In cases where a device tries to read more bytes than the block device
contains, the error is vague: "device requires X bytes, block backend
provides Y bytes".
This patch changes the errors of this function to include the block
backend name, the device id and device type name where appropriate.

This commit was created with scripts/clean-includes:
./scripts/clean-includes --git include include/*/*.h include/*/*/*.h
All .c should include qemu/osdep.h first. The script performs three
related cleanups:
* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c already includes
it. Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
Drop these, too.

The ifdef out of which it is moved is not quite right: do_interrupt is
only needed for system mode. Move it to the top of a different ifdef
block, which preserves its position within the structure for that case.

This patch implements a 32 half word FIFO as per imx serial device
specifications. If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters. On expiry,
AGTIM will be set triggering an interrupt. AGTIM timer resets when
there is activity in the receive FIFO.
Otherwise, RRDY is set when trigger level is exceeded. The receive
trigger level is 8 in newer kernel versions and 1 in older ones.
This change will break migration compatibility for the imx boards.

[PMM: commit message tidyups]

Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.
This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.
Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.

Now than we can access the M-profile bank index
definitions from the target-agnostic "cpu-qom.h"
header, we don't need the huge "cpu.h" anymore
(except in hw/arm/armv7m.c). Reduce its inclusion
to the source unit.

"target/arm/cpu.h" is target specific, any file including it
becomes target specific too, thus this is the same for any file
including "hw/misc/xlnx-versal-crl.h".
"hw/misc/xlnx-versal-crl.h" doesn't require any target specific
definition however, only the target-agnostic QOM definitions
from "target/arm/cpu-qom.h". Include the latter header to avoid
tainting unnecessary objects as target-specific.
