Peter Maydell 1a7917210b hw/arm/stellaris: Correct handling of GPTM TAR register
We don't implement very much of the GPTM TAR register, and what we
do is wrong. The "are we in RT mode?" field is in s->config, not
s->control. Correct this, use LOG_UNIMP rather than hw_error()
for the cases we don't support, and avoid an unlabelled fallthrough
that makes Coverity complain.

Peter Maydell 7e7e5858f8 hw/arm/omap1: Avoid unintended sign extension writing omap_rtc YEARS_REG
When writing to the YEARS_REG register, if the year value is
99 then the multiplication by 31536000 will overflow into
the sign bit of a 32 bit value and then be erroneously
sign-extended if time_t is 64 bits. Add a cast to avoid this.

Juan Quintela 8f1e884b38 savevm: Remove all the unneeded version_minimum_id_old (arm)
After commit 767adce2d, they are redundant.  This way we don't assign them
except when needed.  Once there, there were lots of cases where the ".fields"
indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (apart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Michael S. Tsirkin caa881abe0 pxa2xx: avoid buffer overrun on incoming migration
CVE-2013-4533

s->rx_level is read from the wire and used to determine how many bytes
to subsequently read into s->rx_fifo[]. If s->rx_level exceeds the
length of s->rx_fifo[] the buffer can be overrun with arbitrary data
from the wire.

Fix this by validating rx_level against the size of s->rx_fifo.

Peter Maydell 3078e848fa hw/arm/virt: Put GIC register banks on 64K boundaries
For an AArch64 CPU which supports 64K pages, having the GIC
register banks at 4K offsets is potentially awkward. Move
them out to being at 64K offsets. (This is harmless for
AArch32 CPUs and for AArch64 CPUs with 4K pages, so it is simpler
to use the same offsets everywhere than to try to use 64K offsets
only for AArch64 host CPUs.)

Peter Maydell 6420474384 hw/arm/virt: Create the GIC ourselves rather than (ab)using a15mpcore_priv
Rather than having the virt machine model create an a15mpcore_priv
device regardless of the actual CPU type in order to instantiate the GIC,
move to having the machine model create the GIC directly. This
corresponds to a system which uses a standalone GIC (eg the GIC-400)
rather than the one built in to the CPU core.

The primary motivation for this is to support the Cortex-A57,
which for a KVM configuration will use a GICv2, which is not
built into the CPU.

Peter Maydell d4715c4183 hw/arm: Stop specifying integratorcp as the default board
Currently for both qemu-system-arm and qemu-system-aarch64
the default board model if the user doesn't specify one
is the 'integratorcp'. This is a totally arbitrary historical
accident since it was the first board to be modelled.
That board is now just one target among many for us, and
is a very poor choice of default:
 * it's an ancient board that is now only found in the
   junkpiles of longtime ARM/Linux hackers, if at all
 * it's an ARMv5 CPU, when most distros are now assuming
   ARMv7
 * it's pretty much unmaintained in QEMU
 * it doesn't even have versatilepb's advantage of
   supporting PCI

Making it or any other board the default serves only
to confuse people new to ARM who expect something more
like the x86 monoculture. Remove the is_default marker
from integratorcp, and don't set it for any other board,
to give users a nudge that they need to think about
which board they want a QEMU model of. (QEMU will produce
the admittedly slightly cryptic error "No machine found.")

Peter Maydell 9948c38bd9 vexpress: Set reset-cbar property for CPUs
Newer versions of the Linux kernel (as of commit bc41b8724 in 3.12)
now assume that if the CPU is a Cortex-A9 and the reset value of the
PERIPHBASE/CBAR register is zero then the CPU is a specific buggy
single core A9 SoC, and will not try to start other cores. Since we
now have a CPU property for the reset value of the CBAR, we can
just fix the vexpress board model to correctly set CBAR so SMP
works again. To avoid duplicate boilerplate code in both the A9
and A15 daughterboard init functions, we split out the CPU and
private memory region init to its own function.

Peter Maydell 4cc35614a0 target-arm: Store AIF bits in env->pstate for AArch32
To avoid complication in code that otherwise would not need to
care about whether EL1 is AArch32 or AArch64, we should store
the interrupt mask bits (CPSR.AIF in AArch32 and PSTATE.DAIF
in AArch64) in one place consistently regardless of EL1's mode.
Since AArch64 has an extra enable bit (D for debug exceptions)
which isn't visible in AArch32, this means we need to keep
the enables in env->pstate. (This is also consistent with the
general approach we're taking that we handle 32 bit CPUs as
being like AArch64/ARMv8 CPUs but which only run in 32 bit mode.)

Peter Crosthwaite 7fcd57e80d arm/xilinx_zynq: Always instantiate the GEMs
Don't conditionalise GEM instantiation on networking attachments. The
device should always be present even if not attached to a network.

This allows for probing of the device by expectant guests (such as
OS's).  This is needed because sysbus (or AXI in Xilinx's real hw case)
is not self identifying so the guest has no dynamic way of detecting
device absence.

Also allows for testing of the GEM in loopback mode with -net none.

Stefan Weil 7dbc1158bc mainstone: Fix duplicate array values for key 'space'
cgcc reported a duplicate initialisation. Mainstone includes a matrix
keyboard where two different positions map to 'space'.

QEMU uses the reversed mapping and does not map 'space' to two different
matrix positions.

Some other keys are either missing or might be mapped wrongly (cf. Linux
kernel code). Don't fix these until someone can test them with real
hardware, but add TODO comments.

Markus Armbruster 837d37167d sysbus: Set cannot_instantiate_with_device_add_yet
device_add plugs devices into suitable bus.  For "real" buses, that
actually connects the device.  For sysbus, the connections need to be
made separately, and device_add can't do that.  The device would be
left unconnected, and could not possibly work.

Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.

Set it in their abstract base's class init function
sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

Markus Armbruster efec3dd631 qdev: Replace no_user by cannot_instantiate_with_device_add_yet
In an ideal world, machines can be built by wiring devices together
with configuration, not code.  Unfortunately, that's not the world we
live in right now.  We still have quite a few devices that need to be
wired up by code.  If you try to device_add such a device, it'll fail
in sometimes mysterious ways.  If you're lucky, you get an
unmysterious immediate crash.

To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad.  The device model is still omitted from
help, but is available anyway.

Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.

This commit clarifies no_user's purpose.  Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy.  While there, make it
bool.

Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale.  The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.

With that done, the regression fix is hopefully acceptable.
