Instead of playing with bit shifting, add two unions (one for 32-bit
values, one for 64-bit ones) to access all the DSP elements with the
correct type.
This make the code easier to read and less error prone, and allow GCC
to vectorize the code in some cases.

In the initial conversion of CPU models to QOM types, model names were
mapped 1:1 to type names. As a side effect this gained us a type "any",
which is now a device.
To avoid "-device any" silliness and to pave the way for compiling
multiple targets into one executable, adopt a <name>-<arch>-cpu scheme.
This leads to names like arm926-arm-cpu but is easiest to handle.
No functional changes for -cpu arguments or -cpu ? output.

We don't know pre-init time whether the device we're exposing is PCIe
or legacy PCI. We could ask for it to be specified via a device
option, but that seems like too much to ask of the user. Instead we
can assume everything will be PCIe, which makes PCI-core allocate
enough config space. Removing the flag during init leaves the space
allocated, but allows legacy PCI devices to report the real device
config space size to rest of Qemu.

Traditional PCI config space access is achieved by writing a 32 bit
value to io port 0xcf8 to identify the bus, device, function and config
register. Port 0xcfc then contains the register in question. But if you
write the appropriate pair of magic values to 0xcf9, the machine will
reboot. Spectacular! And not standardised in any way (certainly not part
of the PCI spec), so different chipsets may have different requirements.
Booo.
In the PIIX3 spec, IO port 0xcf9 is specified as the Reset Control
Register. Bit 1 (System Reset, SRST) would normally differentiate between
soft reset and hard reset, but we ignore the difference beyond allowing
the guest to read it back.
RHBZ reference: 890459
This patch introduces the following overlap between the preexistent
"pci-conf-idx" region and the "piix3-reset-control" region just being
added. Partial output from "info mtree":
I/O
0000000000000000-000000000000ffff (prio 0, RW): io
0000000000000cf8-0000000000000cfb (prio 0, RW): pci-conf-idx
0000000000000cf9-0000000000000cf9 (prio 1, RW): piix3-reset-control
I sanity-checked the patch by booting a RHEL-6.3 guest and found no
problems. I summoned gdb and set a breakpoint on rcr_write() in order to
gather a bit more confidence. Relevant frames of the stack:
kvm_handle_io (port=3321, data=0x7f3f5f3de000, direction=1, size=1,
count=1) [kvm-all.c:1422]

size=1, access_size_min=1,

[memory.c:334]
rcr_write (opaque=0x7f3f6227afb0, addr=0, val=6, len=1)
[hw/piix_pci.c:498]
The dispatch happens in ioport_write(); "index=0" means byte-wide access:
static void ioport_write(int index, uint32_t address, uint32_t data)
{
static IOPortWriteFunc * const default_func[3] = {
default_ioport_writeb,
default_ioport_writew,
default_ioport_writel
};
IOPortWriteFunc *func = ioport_write_table[index][address];
if (!func)
func = default_func[index];
func(ioport_opaque[address], address, data);
}
The "ioport_write_table" and "ioport_opaque" arrays describe the flattened
IO port space. The first array is less interesting (it selects a thunk
function). The "ioport_opaque" array is interesting because it decides how
writing to the port is implemented ultimately.
4-byte wide access to 0xcf8 (pci-conf-idx):
(gdb) print ioport_write_table[2][0xcf8]
$1 = (IOPortWriteFunc *) 0x7f3f5f6d99ba <ioport_writel_thunk>
(gdb) print \
((struct MemoryRegionIORange*)ioport_opaque[0xcf8])->mr->ops.write
$2 = (void (*)(void *, hwaddr, uint64_t, unsigned int))
0x7f3f5f5575cb <pci_host_config_write>
1-byte wide access to 0xcf9 (piix3-reset-control):
(gdb) print ioport_write_table[0][0xcf9]
$3 = (IOPortWriteFunc *) 0x7f3f5f6d98d0 <ioport_writeb_thunk>
(gdb) print \
((struct MemoryRegionIORange*)ioport_opaque[0xcf9])->mr->ops.write
$4 = (void (*)(void *, hwaddr, uint64_t, unsigned int))
0x7f3f5f6b42f1 <rcr_write>
The higher priority of "piix3-reset-control" ensures that the 0xcf9
entries in ioport_write_table / ioport_opaque will always belong to it,
independently of its relative registration order versus "pci-conf-idx".

1. rule generating timestamp has side effect.
Thus cleanup on error does not work.
2. rule for handling timestamp is too generic.

might try to create it using this rule which
