Implement a model of the Message Handling Unit (MHU) found in
the Arm SSE-200. This is a simple device which just contains
some registers which allow the two cores of the SSE-200

5aeb368966 hw/misc/armsse-cpuid: Implement SSE-200 CPU_IDENTITY register block
The SSE-200 has a CPU_IDENTITY register block, which is a set of
read-only registers. As well as the usual PID/CID registers, there
is a single CPUID register which indicates whether the CPU is CPU 0
or CPU 1. Implement a model of this register block.

701189e311 hyperv: factor out arch-independent API into hw/hyperv
A significant part of hyperv.c is not actually tied to x86, and can
be moved to hw/.

This will allow to maintain most of Hyper-V and VMBus
target-independent, and to avoid conflicts with inclusion of
arch-specific headers down the road in VMBus implementation.

Also this stuff can now be opt-out with CONFIG_HYPERV.

211e701d66 hw/misc/tz-msc: Model TrustZone Master Security Controller
Implement a model of the TrustZone Master Securtiy Controller,
as documented in the Arm CoreLink SIE-200 System IP for
Embedded TRM  (DDI0571G):
  https://developer.arm.com/products/architecture/m-profile/docs/ddi0571/g

The MSC is intended to sit in front of a device which can
be a bus master (eg a DMA controller) and programmably gate
its transactions. This allows a bus-mastering device to be
controlled by non-secure code but still restricted from
making accesses to addresses which are secure-only.

Implement the Arm TrustZone Memory Protection Controller, which sits

 * it always permits accesses
 * it doesn't implement most of the registers
 * it doesn't implement the interrupt or other behaviour
   for blocked transactions

ab7a75b553 configure: Rename CONFIG_IVSHMEM to CONFIG_IVSHMEM_DEVICE
The current CONFIG_IVSHMEM is confusing, because it looks like it's a
flag for "do we have ivshmem support?", but actually it's a flag for
"is the ivshmem PCI device being compiled?" (and implicitly "do we
have ivshmem support?" is tested with CONFIG_EVENTFD).

Rename it to CONFIG_IVSHMEM_DEVICE to clear this confusion up;
shortly we will add a new CONFIG_IVSHMEM which really does indicate
whether the host can support ivshmem.

54a5ba13a9 target-arm: Implement BCM2835 hardware RNG
Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.

This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.

Changes since v1:
 * Prevented guest from writing [31..20] bits in rng_status
 * Removed redundant minimum_version_id_old
 * Added field entries for the state
 * Changed realize function to reset

c2da8a8b90 ast2400: add a memory controller device model
The uboot in the previous release of the SDK was using a hardcoded
value for memory size. This is not true anymore, the value is now
retrieved from the memory controller.

Below is a model for this device, only supporting unlock and
configuration. Without it, we endup running a guest with 64MB, which
is a bit low nowdays. It uses a 'silicon-rev' property and ram_size to
build a default value. Some bits should be linked to SCU strapping
registers but it seems a bit complex to add for the current need.

The model is ready for the AST2500 SOC.

1c8a2388aa hw/misc: Add a model for the ASPEED System Control Unit
The SCU is a collection of chip-level control registers that manage the
various functions supported by ASPEED SoCs. Typically the bits control
interactions with clocks, external hardware or reset behaviour, and we
can largly take a hands-off approach to reads and writes.

Firmware makes heavy use of the state to determine how to boot, but the
reset values vary from SoC to SoC (eg AST2400 vs AST2500). A qdev
property is exposed so that the integrating SoC model can configure the
silicon revision, which in-turn selects the appropriate reset values.
Further qdev properties are exposed so the board model can configure the
board-dependent hardware strapping.

Almost all provided AST2400 reset values are specified by the datasheet.
The notable exception is SOC_SCRATCH1, where we mark the DRAM as
successfully initialised to avoid unnecessary dark corners in the SoC's
u-boot support.

34fa7e83e1 hw/mips: implement ITC Configuration Tags and Storage Cells
Implement ITC as a single object consisting of two memory regions:

1) tag_io: ITC Configuration Tags (i.e. ITCAddressMap{0,1} registers) which
are accessible by the CPU via CACHE instruction. Also adding
MemoryRegion *itc_tag to the CPUMIPSState so that CACHE instruction will
dispatch reads/writes directly.

2) storage_io: memory-mapped ITC Storage whose address space is configurable
(i.e. enabled/remapped/resized) by writing to ITCAddressMap{0,1} registers.

ITC Storage contains FIFO and Semaphore cells. Read-only FIFO bit in the
ITC cell tag indicates the type of the cell. If the ITC Storage contains
both types of cells then FIFOs are located before Semaphores.

Since issuing thread can get blocked on the access to a cell (in E/F
Synchronized and P/V Synchronized Views) each cell has a bitmap to track
which threads are currently blocked.
