Instead of calling openrisc_env_get_cpu(), casting to CPU() via the
ENV_GET_CPU() compatibility macro and casting back to OPENRISC_CPU(),
just call openrisc_env_get_cpu() directly.
ENV_GET_CPU() is meant as workaround for target-independent code only.

Default to moving back to the IDLE state after the COLLECTING_DATA

A bad guest could crash QEMU by using one of the erase commands
followed by a longer than 5 byte argument (undefined behaviour).

The eth_can_rx() function only checks the first buffers status ("ping"). The
controller should be able to receive into "pong" when ping-pong is enabled.
Checks the active buffer (either "ping" or "pong") when determining can_rx()
rather than just testing "ping".

This is a follow up for several attempts to fix this issue.
Previous incarnations:
1. http://thread.gmane.org/gmane.linux.ubuntu.bugs.general/3156089
https://bugs.launchpad.net/bugs/918791
"qemu-kvm dies when using vmvga driver and unity in the guest" bug.
Fix by Serge Hallyn:
https://launchpadlibrarian.net/94916786/qemu-vmware.debdiff
This fix is incomplete, since it does not check width and height
for being negative. Serge weren't sure if that's the right place
to fix it, maybe the fix should be up the stack somewhere.
2. http://thread.gmane.org/gmane.comp.emulators.qemu/166064
by Marek Vasut: "vmware_vga: Redraw only visible area"
This one adds the (incomplete) check to vmsvga_update_rect_delayed(),
the routine just queues the rect updating but does no interesting
stuff. It is also incomplete in the same way as patch by Serge,
but also does not touch width&height at all after adjusting x&y,
which is wrong.
As far as I can see, when processing guest requests, the device
places them into a queue (vmsvga_update_rect_delayed()) and
processes this queue in different place/time, namely, in
vmsvga_update_rect(). Sometimes, vmsvga_update_rect() is
called directly, without placing the request to the gueue.
This is the place this patch changes, which is the last
(deepest) in the stack. I'm not sure if this is the right
place still, since it is possible we have some queue optimization
(or may have in the future) which will be upset by negative/wrong
values here, so maybe we should check for validity of input
right when receiving request from the guest (and maybe even
use unsigned types there). But I don't know the protocol
and implementation enough to have a definitive answer.
But since vmsvga_update_rect() has other sanity checks already,
I'm adding the missing ones there as well.
Cc'ing BALATON Zoltan and Andrzej Zaborowski who shows in `git blame'
output and may know something in this area.
If this patch is accepted, it should be applied to all active
stable branches (at least since 1.1, maybe even before), with
minor context change (ds_get_*(s->vga.ds) => s->*). I'm not
Cc'ing -stable yet, will do it explicitly once the patch is
accepted.
BTW, these checks use fprintf(stderr) -- it should be converted
to something more appropriate, since stderr will most likely
disappear somewhere.

Align the device tree blob to a 4KB boundary, not to QEMU's
idea of a page boundary -- the latter is the smallest possible
page size for the architecture, which on ARM is 1KB.
The documentation for Linux does not impose separation
or alignment requirements on the device tree blob, but
in practice some kernels will happily trash the entire
page the initrd ends in after they have finished uncompressing
the initrd. So 4KB-align the DTB to ensure it does not get
trampled by these kernels.

read_splashfile() passes the address of an int variable as size_t *
parameter to g_file_get_contents(), with a cast to gag the compiler.
No problem on machines where sizeof(size_t) == sizeof(int).
Happens to work on my x86_64 box (64 bit little endian): the least
significant 32 bits of the file size end up in the right place
(caller's variable file_size), and the most significant 32 bits
clobber a place that gets assigned to before its next use (caller's
variable file_type).
I'd expect it to break on a 64 bit big-endian box.
Fix up the variable types and drop the problematic cast.

Besides the new value in the version register, this provides:
- ILR support, which includes:
- IDR becoming a pure CPU bitmap, allowing 32 CPUs
- machine check output support (though other parts of QEMU need to
be fixed for it to do something other than immediately reboot the
guest)
- dummy error interrupt support (EISR0/EIMR0 read as zero)
- actually all FSL MPICs get all summary registers returning zero for now,
which includes EISR0/EIMR0
Various refactoring is done to support these changes and to ease
new functionality (e.g. a more flexible way of declaring regions).
Just as the code was already not a full implementation of MPIC v2.0,
this is not a full implementation of MPIC v4.2 -- e.g. it still has only
one bank of MSIs.

Currently, if VIO devices for pseries don't have addresses explicitly
allocated, they get automatically numbered from 0x1000. This is in the
same general range that libvirt will typically assign VIO device addresses.
That means that if there is a device libvirt doesn't know about, and it
gets an address assigned before the libvirt assigned devices are processed,
we can end up with an address conflict (qemu will abort with an error).
While the real solution is to teach libvirt about the other devices, so it
can correctly manage the whole allocation, this patch reduces the interim
inconvenience by moving qemu allocations to a range that libvirt is less
likely to conflict with.
Because the guest gets the device addresses through the device tree, these
addresses are truly arbitrary and can be changed without breaking guests.

Multiple - even many - PCI host bridges (i.e. PCI domains) are very
common on real PAPR compliant hardware. For reasons related to the
PAPR specified IOMMU interfaces, PCI device assignment with VFIO will
generally require at least two (virtual) PHBs and possibly more
depending on which devices are assigned.
At the moment the qemu PAPR PCI code will not deal with this well,
leaving several crucial parameters of PHBs other than the default one
uninitialized. This patch reworks the code to allow this.
Every PHB needs a unique BUID (Bus Unit Identifier, the id used for
the PAPR PCI related interfaces) and a unique LIOBN (Logical IO Bus
Number, the id used for the PAPR IOMMU related interfaces). In
addition they need windows in CPU real address space to access PCI
memory space, PCI IO space and MSIs. Properties are added to the PCI
host bridge qdevice to allow configuration of all these.
To simplify configuration of multiple PHBs for common cases, a
convenience "index" property is also added. This can be set instead
of the low-level properties, and will generate suitable values for the
other parameters, different for each index value.
