openrisc: Initial SMP support
Wire in ompic and add basic support for SMP. The OpenRISC is special in
that interrupts for devices are routed to each core's PIC. This is
achieved using the qemu_irq_split utility, but this currently limits
OpenRISC to 2 cores.
This models the reference architecture described in the OpenRISC spec
1.2 proposal.
https://github.com/stffrdhrn/doc/raw/arch-1.2-proposal/openrisc-arch-1.2-rev0.pdf
The changes to the intialization of the sim include:
CPU Reset
o Reset each cpu to the bootstrap PC rather than only a single cpu as
done before.
o During Kernel loading the bootstrap PC is saved in a static global.
Network Initialization
o Connect the interrupt to each CPU
o Use more simple sysbus_mmio_map() rather than memory_region_add_subregion()
Sim Initialization
o Initialize the pic and tick timer per cpu
o Wire in the OMPIC if SMP is enabled
o Wire the serial irq to each CPU using qemu_irq_split()

s390x/tcg: low-address protection support
This is a neat way to implement low address protection, whereby
only the first 512 bytes of the first two pages (each 4096 bytes) of
every address space are protected.
Store a tec of 0 for the access exception, this is what is defined by
Enhanced Suppression on Protection in case of a low address protection
(Bit 61 set to 0, rest undefined).
We have to make sure to to pass the access address, not the masked page
address into mmu_translate*().
Drop the check from testblock. So we can properly test this via
kvm-unit-tests.
This will check every access going through one of the MMUs.

accel/tcg: allow to invalidate a write TLB entry immediately
Background: s390x implements Low-Address Protection (LAP). If LAP is
enabled, writing to effective addresses (before any translation)
0-511 and 4096-4607 triggers a protection exception.
So we have subpage protection on the first two pages of every address
space (where the lowcore - the CPU private data resides).
By immediately invalidating the write entry but allowing the caller to
continue, we force every write access onto these first two pages into
the slow path. we will get a tlb fault with the specific accessed
addresses and can then evaluate if protection applies or not.
We have to make sure to ignore the invalid bit if tlb_fill() succeeds.

We must therefore really only unhalt the CPU if we don't have a WAIT

load a new PSW and change the state to operating.

s390x/tcg: implement STOP and RESET interrupts for TCG
Implement them like KVM implements/handles them. Both can only be
triggered via SIGP instructions. RESET has (almost) the lowest priority if
the CPU is running, and the highest if the CPU is STOPPED. This is handled
in SIGP code already. On delivery, we only have to care about the
"CPU running" scenario.
STOP is defined to be delivered after all other interrupts have been
delivered. Therefore it has the actual lowest priority.
As both can wake up a CPU if sleeping, indicate them correctly to
external code (e.g. cpu_has_work()).

So turn INTERRUPT_EXT into a mask and properly indicate the kind of
external interrupt. Floating interrupts will have to moved out of
one CPU instance later once we have SMP support.
The only floating external interrupts used right now are SERVICE
interrupts, so let's use that name. Following patches will clean up

build: Fix dtc-checkout race condition in Makefile

build: automatically handle GIT submodule checkout for dtc
On my system, I see the following with a fresh clone:
% ./configure --disable-gtk --target-list=aarch64-softmmu
% make -j8
GEN aarch64-softmmu/config-devices.mak.tmp
GEN config-host.h
mkdir -p dtc/libfdt

mkdir -p dtc/tests
GEN qemu-options.def
[snip]
GEN migration/trace.h
make: *** [git-submodule-update] Error 1
make: *** Waiting for unfinished jobs....
Upon closer inspection, the root cause of the error is:
% git submodule update --init ui/keycodemapdb dtc
fatal: destination path 'dtc' already exists and is not an empty directory.
Clone of 'git://git.qemu-project.org/dtc.git' into submodule path 'dtc' failed
This patch fixes this race condition by forcing the 'dtc/%' rule which caused
'dtc' to be non-empty to wait on '.git-submodule-status'.

seabios: update to 1.11 prerelease
This is the seabios update for qemu 2.11. Well, almost, seabios is in
freeze for the upcoming 1.11 release. This updates seabios to current
git master snapshot, and it will be updated again to 1.11 final before
the 2.11 release.
With this two-step seabios gets some more wide testing before the actual
release and the update to 1.11 final (which will most likely happen
after qemu freeze) should have bugfix patches only.

sun4u: update PCI topology to include simba PCI bridges
This patch updates the sun4u model to being much closer to a real Ultra 5
by moving devices behind the 2 simba PCI bridges (A and B) as found on real
hardware.
The most noticeable change introduced by this patchset is that in-built devices
are no longer attached to the PCI root bus, but instead behind PCI bridge A.
Along with this the interrupt routing is updated accordingly to match the
official documentation.
Since the existing code currently bypasses the PCI bridge interrupt
swizzling, the interrupt mapping functions are reorganised so that
pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is
used by the PCI host bridge.
Behind the sabre PCI host bridge, the PCI IO space now needs to be
split into two separate halves at 0x8000000. Therefore we also setup a new
PCI IO space region of increased size on the PCI host bridge and enable
32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI
bridge B correctly.
As part of this change we also combine the onboard sunhme NIC and the ebus
into a single multi-function device as done on a real Ultra 5. For other
NICs the existing behaviour is preserved, i.e. we initialise them and
place them into the next free slot on PCI bus B.
Finally we mark the physically unavailable slots (plus slot 0 in busA) as
reserved to ensure that users can't plug devices into non-existent slots
which will break interrupt routing.
Note: since this commit changes PCI topology and interrupt routing, an
updated openbios-sparc64 binary is included with this commit containing the
associated changes to maintain bisectability.

scsi: reject configurations with logical block size > physical block size
Logical block size of a SCSI disk should never be larger than
physical block size. From an ATA/SCSI perspective, it makes no sense
to have the logical block size greater than the physical block size,
and it cannot even be effectively expressed in the command set. The
whole point of adding the physical block size to the ATA/SCSI command
set was to communicate a desire for a larger block size (than logical),
while maintaining backwards compatibility with legacy 512 byte block
size.
When setting logical_block_size > physical_block_size, QEMU cannot express
it in READ CAPACITY(16) output, and all it can do is set the physical
block exponent to 0 (i.e. logical_block_size == physical_block_size).
Reporting the error properly, however, is better.
