The sequence of reading from eeprom is "offset by one" moved because of a false
detection of a clock cycle after an eeprom reset. Keeping the last clock value
after a reset keeps it in sync.

Add id field to DeviceState. Make "info qtree" print it.
This helps users and management apps identifying devices in monitor
output, which is especially useful with otherwise identical devices
such as two virtio disks.
This patch doesn't add a way to set the id, followup patches will do.

This add support for switching devices into a compatibility mode
using device properties. Machine types can have a list of properties
for specific devices attached to allow the easy creation of machine
types compatible to older qemu versions.

This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.

Hi,
Whoever wrote this migrate_set_speed function is totally stupid.
Any failed or completed migration keeps its state to allow probing of
migration data, but has no associated file anymore. It is, thus,
possible to crash qemu by calling migrate_set_speed after a migration
is finished (or failed, or cancelled), but before another one starts.
This patch fixes it.

This patch removes dead i386 assembly code from softmmu_header.h.
The code is conditional on ASM_SOFTMMU, which is never defined.
Optimisation for the fast path is already handled by tcg_out_qemu_ld()
and tcg_out_qemu_st(), so there seems to be little need for this code.

Instead of doing our own check for protocols which fails because raw isn't
formally a protocol but special cased in find_protocol specify the BDRV_O_FILE

Using int for cpu_{in, out}[bwl] is inconsistent with other part
because for address or value, uintN_t is used by other qemu part.
At least, softmmu, CPU{Read, Write}MemoryFunc, pci, target_phys_addr_t
and the callers of cpu_{in, out}[bwl]().
This patch removes the inconsistency.
IO port has its own address space so define pio_addr_t as uint32_t
because PCI io space width is 32bit.
And use uint{32, 16, 8}_t for ioport value.
Changing signedness of value might cause subtle issue. However
only a suspicious caller is kvm_handle_io() which is ok. And other callers
pass unsigned value in the first place.
