d8ba780b6a target-arm: Define and use ARM_FEATURE_CBAR
Some processors (notably A9 within Highbank) define and use the
CP15 configuration base address (CBAR). This is vendor specific
so its best implemented as a CPU property (otherwise we would need
vendor specific child classes for every ARM implementation).

This patch prepares support for converting CBAR reset value to
a CPU property by moving the CP registration out of the CPU
init fn, as registration will need to happen at realize time
to pick up any property updates. The easiest way to do this
is via definition of a new ARM_FEATURE to flag the existence
of the register.

3671cd879a target-arm/helper.c: Allow cp15.c15 dummy override
The cp15.c15 space is implementation defined. Currently there is a
dummy placeholder register RAZing it. Allow overriding of this RAZ
so implementations of specific registers can take precedence.

0163a2dc80 Fix NOR flash device ID reading
Fix NOR flash manufacturer and device ID reading.  This now
properly takes into account device widths and device max widths
as required.  The reading of these IDs uses the same max_width
dependent addressing as CFI queries.

The old code remains for chips that don't specify a device width,
as the new code relies on a device width being set in order to
properly operate.  The existing code seems very broken.

Only ident0 and ident1 are used in the new code, as other fields
relate to the lock state of blocks in flash.

The VExpress flash configuration has been updated to match
the new code, as the existing definition was 'wrong' in order
to return the expected results with the broken device ID code.

4433e660e3 Fix CFI query responses for NOR flash
This change fixes the CFI query responses to handle NOR device
widths that are different from the bank width.  Support is also
added for multi-width devices in a x8 configuration.  This is
typically x8/x16 devices, but the CFI specification mentions
x8/x32 devices so those should be supported as well if they
exist.
The query response data is now replicated per-device in the bank,
and is adjusted for x16 or x32 parts configured in x8 mode.

The existing code is left in place for boards that have not
been updated to specify an explicit device_width.  The VExpress
board has been updated in an earlier patch in this series so
this is the only board currently affected.

fa21a7b13e Add max device width parameter for NOR devices
For handling CFI and device ID reads, we need to not only know the
width that a NOR flash device is configured for, but also its maximum
width.  The maximum width addressing mode is used for multi-width
parts no matter which width they are configured for.  The most common
case is x16 parts that also support x8 mode.  When configured for x8
operation these devices respond to CFI and device ID requests differently
than native x8 NOR parts.

1997b48527 Add device-width property to pflash_cfi01
The width of the devices that make up the flash interface
is required to mask certain commands, in particular the
write length for buffered writes.  This length will be presented
to each device on the interface by the program writing the flash,
and the flash emulation code needs to be able to determine
the length of the write as recieved by each flash device.
The device-width defaults to the bank width which should
maintain existing behavior for platforms that don't need
this change.
This change is required to support buffered writes on the
vexpress platform that has a 32 bit flash interface with 2
16 bit devices on it.

f46e720a82 qemu_opts_parse(): always check return value
qemu_opts_parse() can always return NULL, even if the QemuOptsList.desc in
question would be trivial to satisfy (eg. because it's empty). For
example:

qemu_opts_parse()
  opts_parse()
    qemu_opts_create()
      id_wellformed()

In practice:

  $ .../qemu-system-x86_64 -acpitable id=3
  qemu-system-x86_64: -acpitable id=3: Parameter 'id' expects an identifier
  **
  ERROR:vl.c:3491:main: assertion failed: (opts != NULL)
  Aborted (core dumped)

  $ .../qemu-system-x86_64 -smbios id=3
  qemu-system-x86_64: -smbios id=3: Parameter 'id' expects an identifier
  Segmentation fault (core dumped)

I checked all qemu_opts_parse() invocations (and all drive_def()
invocations too, because it blindly forwards the former's retval). Only
the two above examples look problematic.

Video streaming detection heuristics in spice-server have problems
keeping modern desktop animations (as done by gnome shell) and real
video playback apart.  This leads to jpeg compression artefacts on
your desktop, due to spice using mjpeg to send what it thinks is

Turn off video detection by default to avoid these artifacts.

5d0e2280cc acpi.pci,pc,memory core fixes
Most notably this includes changes to exec to support
 full 64 bit addresses.
 
 This also flushes out patches that got queued during 1.7 freeze.
 There are new tests, and a bunch of bug fixes all over the place.
 There are also some changes mostly useful for downstreams.
 
 I'm also listing myself as pc co-maintainer. I'm doing this reluctantly,
 but this seems to be necessary to make sure patches are not lost or delayed too
 much, and posting the MAINTAINERS patch did not seem to make anyone else
 volunteer.

Merge remote-tracking branch 'mst/tags/for_anthony' into staging

acpi.pci,pc,memory core fixes

Most notably this includes changes to exec to support
full 64 bit addresses.

This also flushes out patches that got queued during 1.7 freeze.
There are new tests, and a bunch of bug fixes all over the place.
There are also some changes mostly useful for downstreams.

I'm also listing myself as pc co-maintainer. I'm doing this reluctantly,
but this seems to be necessary to make sure patches are not lost or delayed too
much, and posting the MAINTAINERS patch did not seem to make anyone else
volunteer.

f671d173c7 block/vvfat: Fix compiler warnings for OpenBSD
The buildbot shows these compiler warnings:

block/vvfat.c: In function 'create_short_and_long_name':
block/vvfat.c:620: warning: array size (8) smaller than bound length (11)
block/vvfat.c:620: warning: array size (8) smaller than bound length (11)
block/vvfat.c:635: warning: array size (8) smaller than bound length (11)
block/vvfat.c:635: warning: array size (8) smaller than bound length (11)

They are caused by tricky code where 8 characters for the name are followed
by 3 characters for the extension, and some operations touch both name and
extension.

Using an 11 character name which includes the extension fixes the compiler
warning, satisfies cppcheck, valgrind and maybe other static and dynamic
code checkers, and even simplifies some parts of the code.

53cb28cbfe exec: separate sections and nodes per address space
Every address space has its own nodes and sections, but
it uses the same global arrays of nodes/section.

This limits the number of devices that can be attached
to the guest to 20-30 devices. It happens because:
 - The sections array is limited to 2^12 entries.
 - The main memory has at least 100 sections.
 - Each device address space is actually an alias to
   main memory, multiplying its number of nodes/sections.

Remove the limitation by using separate arrays of
nodes and sections for each address space.

7a10ef51c2 hpet: enable to entitle more irq pins for hpet
Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.

On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.

Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

0d63b2dd31 hpet: inverse polarity when pin above ISA_NUM_IRQS
According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)

We fold the emulation of this inversion inside the hpet logic.

4c41425d2e pci: fix pci bridge fw path
qemu uses "pci" as name for pci bridges in the firmware device path.
seabios expects "pci-bridge".  Result is that bootorder is broken for
devices behind pci bridges.

Some googling suggests that "pci-bridge" is the correct one.  At least
PPC-based Apple machines are using this.  See question "How do I boot
from a device attached to a PCI card" here:
	http://www.netbsd.org/ports/macppc/faq.html

So lets change qemu to use "pci-bridge" too.
