This patch doesn _not_ include disabling of cp15 access and base-updated
data abort model (that will be required to emulate chips based on a
ARM7TDMI), because:
* no ARM7TDMI chips are currently emulated (or planned)
* those features aren't strictly necessary for my purposes (SA-1 core
emulation).
All v5 models are handled as they are v5T. Internally we still have a
check if the model is a v5(T) or v5TE, but as all emulated cores are
v5TE, those two cases are simply aliased (for now).

currently, we calculate amount of data produced at each step by

The same code is used in vnc-enc-tight.c and vnc-enc-zlib.c,
so fix both cases.
There, there's no actual need to save previous_out value, since

I think it is safe. Please see an updated comment below.

ppce500_mpc8544ds: Fix compile with --enable-debug and --disable-kvm
When configured with --enable-debug, we compile without optimization.
This means that the function mpc8544_copy_soc_cell() in ppce500_mpc8544ds.c

Delay creation of pseries device tree until reset
At present, the 'pseries' machine creates a flattened device tree in the
machine->init function to pass to either the guest kernel or to firmware.
However, the machine->init function runs before processing of -device
command line options, which means that the device tree so created will
be (incorrectly) missing devices specified that way.
Supplying a correct device tree is, in any case, part of the required
platform entry conditions. Therefore, this patch moves the creation and
loading of the device tree from machine->init to a reset callback. The
setup of entry point address and initial register state moves with it,
which leads to a slight cleanup.
This is not, alas, quite enough to make a fully working reset for pseries.
For that we would need to reload the firmware images, which on this
machine are loaded into RAM. It's a step in the right direction, though.

pseries: Abolish envs array
Currently the pseries machine init code builds up an array, envs, of
CPUState pointers for all the cpus in the system. This is kind of
pointless, given the generic code already has a perfectly good linked list
of the cpus.
In addition, there are a number of places which assume that the cpu's
cpu_index field is equal to its index in this array. This is true in
practice, because cpu_index values are just assigned sequentially, but
it's conceptually incorrect and may not always be true.
Therefore, this patch abolishes the envs array, and explicitly uses the

virtio-balloon: fixed endianness bug in the config space
The specification for the virtio balloon device requres that the values
in the config space be encoded little-endian. This differs from most
virtio things, where guest-native endian is the norm.
Currently, the qemu virtio-balloon code correctly makes the conversion
on get_config(), but doesn't on set_config for the 'actual' field. The
kernel driver, on the other hand, correctly converts when setting the
actual field, but does not convert when reading the config space. The
upshot is that virtio-balloon will only work correctly if both host and
guest are LE, making all the conversions nops.
This patch corrects the qemu side, correctly doing host-native <-> LE
conversions when accessing the config space. This won't break any setups
that aren't already broken, and fixes the case of BE host, LE guest.
Fixing the BE guest case will require kernel fixes as well.

has something like a raid array on the two drives, guest may start failing
that array or kick "missing" drives which may result in a mess - this is

Do not delete BlockDriverState when deleting the drive
When removing a drive from the host-side via drive_del we currently have
the following path:
drive_del
qemu_aio_flush()
bdrv_close() // zaps bs->drv, which makes any subsequent I/O get
// dropped. Works as designed
drive_uninit()
bdrv_delete() // frees the bs. Since the device is still connected to
// bs, any subsequent I/O is a use-after-free.
The value of bs->drv becomes unpredictable on free. As long as it
remains null, I/O still gets dropped, however it could become non-null
at any point after the free resulting SEGVs or other QEMU state
corruption.
To resolve this issue as simply as possible, we can chose to not
actually delete the BlockDriverState pointer. Since bdrv_close()
handles setting the drv pointer to NULL, we just need to remove the
BlockDriverState from the QLIST that is used to enumerate the block
devices. This is currently handled within bdrv_delete, so move this
into its own function, bdrv_make_anon().
The result is that we can now invoke drive_del, this closes the file
descriptors and sets BlockDriverState->drv to NULL which prevents futher
IO to the device, and since we do not free BlockDriverState, we don't
have to worry about the copy retained in the block devices.
We also don't attempt to remove the qdev property since we are no longer
deleting the BlockDriverState on drives with associated drives. This
also allows for removing Drives with no devices associated either.

lm32: add Milkymist HPDMC support
This patch adds support for the Milkymist's High Performance Dynamic Memory
Controller. This is just a dumb model without any functionality. While the
real hardware acts for example as a bridge between software and hardware
for sending SDRAM commans, this model will only eat up these commands and
always returns the expected hardware states, eg. PLL locked etc.
