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.)

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.

Near total rewrite of this device model. It is stylistically
obsolete, has numerous coverity fails and is not up to date with latest
Xilinx documentation. Fix.
The registers are flattened into a single array. This greatly simplifies
the MMIO accessor functions.
We take the oppurtunity to update the register Macro definitions to
match the latest TRM. Xilinx has de-documented some regs hence there are
some straight deletions. We only do this however in the case or a stock
read-as-written reset-zero register. Non-zero resets are always
preserved. New register definitions are added as needed.
This all comes with a VMSD version break as the union layout from before
was a bit strange and we are better off without it.

When VM guest programs multicast addresses for
a virtio net card, it supplies a 32 bit
entries counter for the number of addresses.
These addresses are read into tail portion of
a fixed macs array which has size MAC_TABLE_ENTRIES,
at offset equal to in_use.
To avoid overflow of this array by guest, qemu attempts
to test the size as follows:
- if (in_use + mac_data.entries <= MAC_TABLE_ENTRIES) {
however, as mac_data.entries is uint32_t, this sum
can overflow, e.g. if in_use is 1 and mac_data.entries
is 0xffffffff then in_use + mac_data.entries will be 0.
Qemu will then read guest supplied buffer into this
memory, overflowing buffer on heap.

The raven_io_read() and raven_io_write() functions pass and
return values in little-endian format (since the IO op struct
is marked DEVICE_LITTLE_ENDIAN); however they were storing the
values in the buffer to pass to address_space_read/write()
in host-endian order, which meant that on big-endian hosts
the values were inadvertently reversed. Use the *_le_p()
accessors instead so that we are consistent regardless of
host endianness.
Strictly speaking the byte order of the buffer for
address_space_rw() is target byte order (which for PPC
will be BE) but it doesn't actually matter as long as we
are consistent about the marking on the IO op struct and
which stl_*_p().
This bug was probably introduced due to confusion caused by
the two different versions of ldl_p() and friends:
bswap.h defines versions meaning "host endianness access"
cpu-all.h defines versions meaning "target endianness access"
As a target-independent source file prep.c gets the bswap.h
versions; the very similar looking code in ioport.c is
compiled per-target and gets the cpu-all.h versions.

Here is a single last minute fix for 2.0
This changes the HID of the container used to claim
resources for CPU hotplug.
As a result, windows XP SP3 no longer brings up
an annoying "found new hardware" wizard on boot.

dsdt: tweak ACPI ID for hotplug resource device
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
ACPI0004 seems too new:
Windows XP complains about an unrecognized device.
This is a regression since 1.7.
Use PNP0A06 instead - Generic Container Device.
