4b9c264bd2 q35: change default NIC to e1000e
The e1000 NIC is getting old and is not a very good default for a
PCIe machine type.  Change it to e1000e, which should be supported
by a good number of guests.

In particular, drivers for 82574 were added first to Linux 2.6.27 (2008)
and Windows 2008 R2.  This does mean that Windows 2008 will not work
anymore with Q35 machine types and a default "-net nic -net xxx" network
configuration; it did work before because it does have an AHCI driver.
However, Windows 2008 has been declared out of main stream support
in 2015.  It will get out of extended support in 2020.  Windows 2008
R2 has the same end of support dates and, since the two are basically
Vista vs. Windows 7, R2 probably is more popular.

d64e5eabc4 pci: Add support for Designware IP block
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/*)

d9bbfea646 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.

 The RISC-V QEMU port adds the following targets to QEMU:
 
 * riscv32-softmmu
 * riscv64-softmmu
 * riscv32-linux-user
 * riscv64-linux-user
 
 The RISC-V QEMU port supports the following hardware:
 
 * HTIF Console (Host Target Interface)
 * SiFive CLINT (Core Local Interruptor) for Timer interrupts and IPIs
 * SiFive PLIC (Platform Level Interrupt Controller)
 * SiFive Test (Test Finisher) for exiting simulation
 * SiFive UART, PRCI, AON, PWM, QSPI support is partially implemented
 * VirtIO MMIO (GPEX PCI support will be added in a future patch)
 * Generic 16550A UART emulation using 'hw/char/serial.c'
 * MTTCG and SMP support (PLIC and CLINT) on the 'virt' machine
 
 The RISC-V QEMU full system emulator supports 5 machines:
 
 * 'spike_v1.9.1', CLINT, PLIC, HTIF console, config-string, Priv v1.9.1
 * 'spike_v1.10', CLINT, PLIC, HTIF console, device-tree, Priv v1.10

*** 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.

*** Overview ***

The RISC-V QEMU port implements the following specifications:

* RISC-V Instruction Set Manual Volume I: User-Level ISA Version 2.2
* RISC-V Instruction Set Manual Volume II: Privileged ISA Version 1.9.1
* RISC-V Instruction Set Manual Volume II: Privileged ISA Version 1.10

The RISC-V QEMU port supports the following instruction set extensions:

* RV32GC with Supervisor-mode and User-mode (RV32IMAFDCSU)
* RV64GC with Supervisor-mode and User-mode (RV64IMAFDCSU)

The RISC-V QEMU port adds the following targets to QEMU:

* riscv32-softmmu
* riscv64-softmmu
* riscv32-linux-user
* riscv64-linux-user

The RISC-V QEMU port supports the following hardware:

* HTIF Console (Host Target Interface)
* SiFive CLINT (Core Local Interruptor) for Timer interrupts and IPIs
* SiFive PLIC (Platform Level Interrupt Controller)
* SiFive Test (Test Finisher) for exiting simulation
* SiFive UART, PRCI, AON, PWM, QSPI support is partially implemented
* VirtIO MMIO (GPEX PCI support will be added in a future patch)
* Generic 16550A UART emulation using 'hw/char/serial.c'
* MTTCG and SMP support (PLIC and CLINT) on the 'virt' machine

The RISC-V QEMU full system emulator supports 5 machines:

* 'spike_v1.9.1', CLINT, PLIC, HTIF console, config-string, Priv v1.9.1
* 'spike_v1.10', CLINT, PLIC, HTIF console, device-tree, Priv v1.10

112ed241f5 qapi: Empty out qapi-schema.json
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.

9af2398977 Include less of the generated modular QAPI headers
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.

collection of registers for controlling the PPCs and other bits of
glue in the system.  This commit provides the initial skeleton of the
device, implementing just the ID registers, and a couple of read-only
read-as-zero registers.

9eb8040c2d hw/misc/tz-ppc: Model TrustZone peripheral protection controller
Add a model of the TrustZone peripheral protection controller (PPC),
which is used to gate transactions to non-TZ-aware peripherals so
that secure software can configure them to not be accessible to
non-secure software.

5edb1b3fa9 hw/core/split-irq: Device that splits IRQ lines
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.)

4a151677a8 qdev: Add new qdev_init_gpio_in_named_with_opaque()
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.
