Add code needed to get a functional PCI subsytem when using in
conjunction with upstream Linux guest (4.13+). Tested to work against
"e1000e" (network adapter, using MSI interrupts) as well as
"usb-ehci" (USB controller, using legacy PCI interrupts).
Based on "i.MX6 Applications Processor Reference Manual" (Document
Number: IMX6DQRM Rev. 4) as well as corresponding dirver in Linux
kernel (circa 4.13 - 4.16 found in drivers/pci/dwc/*)

QEMU RISC-V Emulation Support (RV64GC, RV32GC)
This release renames the SiFive machines to sifive_e and sifive_u
to represent the SiFive Everywhere and SiFive Unleashed platforms.
SiFive has configurable soft-core IP, so it is intended that these
machines will be extended to enable a variety of SiFive IP blocks.
The CPU definition infrastructure has been improved and there are
now vendor CPU modules including the SiFiVe E31, E51, U34 and U54
cores. The emulation accuracy for the E series has been improved
by disabling the MMU for the E series. S mode has been disabled on
cores that only support M mode and U mode. The two Spike machines
that support two privileged ISA versions have been coalesced into
one file. This series has Signed-off-by from the core contributors.

*** Background ***
"RISC-V is an open, free ISA enabling a new era of processor innovation
through open standard collaboration. Born in academia and research,
RISC-V ISA delivers a new level of free, extensible software and
hardware freedom on architecture, paving the way for the next 50 years
of computing design and innovation."
The QEMU RISC-V port has been developed and maintained out-of-tree for
several years by Sagar Karandikar and Bastian Koppelmann. The RISC-V
Privileged specification has evolved substantially over this period but
has recently been solidifying. The RISC-V Base ISA has been frozon for
some time and the Privileged ISA, GCC toolchain and Linux ABI are now
quite stable. I have recently joined Sagar and Bastian as a RISC-V QEMU
Maintainer and hope to support upstreaming the port.
There are multiple vendors taping out, preparing to ship, or shipping
silicon that implements the RISC-V Privileged ISA Version 1.10. There
are also several RISC-V Soft-IP cores implementing Privileged ISA
Version 1.10 that run on FPGA such as SiFive's Freedom U500 Platform
and the U54‑MC RISC-V Core IP, among many more implementations from a
variety of vendors. See https://riscv.org/ for more details.
RISC-V support was upstreamed in binutils 2.28 and GCC 7.1 in the first
half of 2016. RISC-V support is now available in LLVM top-of-tree and
the RISC-V Linux port was accepted into Linux 4.15-rc1 late last year
and is available in the Linux 4.15 release. GLIBC 2.27 added support
for the RISC-V ISA running on Linux (requires at least binutils-2.30,
gcc-7.3.0, and linux-4.15). We believe it is timely to submit the
RISC-V QEMU port for upstream review with the goal of incorporating
RISC-V support into the upcoming QEMU 2.12 release.
The RISC-V QEMU port is still under active development, mostly with
respect to device emulation, the addition of Hypervisor support as
specified in the RISC-V Draft Privileged ISA Version 1.11, and Vector
support once the first draft is finalized later this year. We believe
now is the appropriate time for RISC-V QEMU development to be carried
out in the main QEMU repository as the code will benefit from more
rigorous review. The RISC-V QEMU port currently supports all the ISA
extensions that have been finalized and frozen in the Base ISA.

Automatic creation of SCSI controllers for "-drive if=scsi" for x86
machines was quite a bad idea (see description of commit f778a82f0c179

far as I know, nobody complained that this is still urgently required
anymore. Time to remove this now.

The previous commit improved compile time by including less of the
generated QAPI headers. This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.
Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent
Perhaps we'll get rid of those some other day.
Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

In my "build everything" tree, a change to the types in
qapi-schema.json triggers a recompile of about 4800 out of 5100
objects.
The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h,
qapi-types.h. Each of these headers still includes all its shards.
Reduce compile time by including just the shards we actually need.
To illustrate the benefits: adding a type to qapi/migration.json now
recompiles some 2300 instead of 4800 objects. The next commit will
improve it further.

Model the Arm IoT Kit documented in
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ecm0601256/index.html
The Arm IoT Kit is a subsystem which includes a CPU and some devices,
and is intended be extended by adding extra devices to form a
complete system. It is used in the MPS2 board's AN505 image for the
Cortex-M33.

In some board or SoC models it is necessary to split a qemu_irq line
so that one input can feed multiple outputs. We currently have
qemu_irq_split() for this, but that has several deficiencies:
* it can only handle splitting a line into two
* it unavoidably leaks memory, so it can't be used
in a device that can be deleted
Implement a qdev device that encapsulates splitting of IRQs, with a
configurable number of outputs. (This is in some ways the inverse of
the TYPE_OR_IRQ device.)

The function qdev_init_gpio_in_named() passes the DeviceState pointer
as the opaque data pointor for the irq handler function. Usually
this is what you want, but in some cases it would be helpful to use
some other data pointer.
Add a new function qdev_init_gpio_in_named_with_opaque() which allows
the caller to specify the data pointer they want.
