Beniamino Galvani 22f90bcb2b hw/net: add support for Allwinner EMAC Fast Ethernet controller
This patch adds support for the Fast Ethernet MAC found on Allwinner
SoCs, together with a basic emulation of Realtek RTL8201CP PHY.

Since there is no public documentation of the Allwinner controller, the
implementation is based on Linux kernel driver.

Beniamino Galvani c4e57af852 util/fifo8: implement push/pop of multiple bytes
The patch adds functions fifo8_push_all() and fifo8_pop_buf() which
can be used respectively to push the content of a memory buffer to the
fifo and to pop multiple bytes obtaining a pointer to the fifo backing
buffer.

In addition, it implements fifo8_num_free() and fifo8_num_used() which
allow to check if a multi-byte operation can be performed.

Claudio Fontana 999b53ec87 disas: Implement disassembly output for A64
Use libvixl to implement disassembly output in debug
logs for A64, for use with both AArch64 hosts and targets.

Signed-off-by: Claudio Fontana <claudio.fontana@linaro.org>
[PMM:
 * added support for target disassembly
 * switched to custom QEMUDisassembler so the output format
   matches what QEMU expects
 * make sure we correctly fall back to "just print hex"
   if we didn't build the AArch64 disassembler because of
   lack of a C++ compiler
 * rename from 'aarch64' to 'arm-a64' because this is a
   disassembler for the A64 instruction set
 * merge aarch64.c and aarch64-cxx.cc into one C++ file
 * simplify the aarch64.c<->aarch64-cxx.cc interface]

Christoffer Dall a9d477c4e3 arm_gic: Add GICC_APRn state to the GICState
The GICC_APRn registers are not currently supported by the ARM GIC v2.0
emulation.  This patch adds the missing state.

Note that we also change the number of APRs to use a define GIC_NR_APRS
based on the maximum number of preemption levels.  This patch also adds
RAZ/WI accessors for the four registers on the emulated CPU interface.

Christoffer Dall 40d225009e arm_gic: Keep track of SGI sources
Right now the arm gic emulation doesn't keep track of the source of an
SGI (which apparently Linux guests don't use, or they're fine with
assuming CPU 0 always).

Add the necessary matrix on the GICState structure and maintain the data
when setting and clearing the pending state of an IRQ and make the state
visible to the guest.

Note that we always choose to present the source as the lowest-numbered
CPU in case multiple cores have signalled the same SGI number to a core
on the system.

Alexey Kardashevskiy f9ee9f9ac2 exec: fix ram_list dirty map optimization
The ae2810c4bb patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).

This fixes hpratio!=1 case to fall back to the slow path.

Martin Husemann dc9a353cf7 qemu 1.7.0 does not build on NetBSD
Do not rely on int8_t (and friends) not being preprocessor
 symbols (or symbols expanding to themselves). On NetBSD (for example) the
 glue(u, SDATA_TYPE) results in u__int8_t, which is undefined. There is no way
 to stop cpp expanding inner macros, so just add the few lines explicitly and
 get rid of the magic.

Igor Mammedov 269e09f3fc add optional 2nd stage initialization to -object/object-add commands
Introduces USER_CREATABLE interface that must be implemented by
objects which are designed to created with -object CLI option or
object-add QMP command.

Interface provides an ability to do an optional second stage
initialization of the object created with -object/object-add
commands. By providing complete() callback, which is called
after the object properties were set.

It allows to:
 * prevents misusing of -object/object-add by filtering out
   objects that are not designed for it.
 * generalize second stage backend initialization instead of
   adding custom APIs to perform it
 * early error detection of backend initialization at -object/
   object-add time rather than through a proxy DEVICE object
   that tries to use backend.

Michael S. Tsirkin db4728e6fe pcihp: generalization of piix4 acpi
Add ACPI based PCI hotplug library with bridge hotplug
support.
Design
   - each bus gets assigned "bsel" property.
   - ACPI code writes this number
     to a new BNUM register, then uses existing
     UP/DOWN registers to probe slot status;
     to eject, write number to BNUM register,
     then slot into existing EJ.

The interface is actually backwards-compatible with
existing PIIX4 ACPI (though not migration compatible).

This is split out from PIIX4 codebase so we can
reuse it for Q35 as well.
