The shipping default setting for the Freescale M5208EVB board is to run
the CPU at 166.67MHz. The current qemu emulation code for this board is
defaulting to 66MHz. This results in time appearing to run way to slowly.
So a "sleep 5" in a standard ColdFire Linux build takes almost 15
seconds in real time to actually complete.
Change the hard coded default to match the default hardware setting.

Almost all block devices are qdevified by now. This allows us to go back
from the BlockBackend to the DeviceState. xen_disk is the last device
that is missing. We'll remember in the BlockBackend if a xen_disk is
attached and can then disable any features that require going from a BB
to the DeviceState.
While at it, clearly mark the function used by xen_disk as legacy even
in its name, not just in TODO comments.

A couple of distributors are compiling their distributions
with "-mcpu=power8" for ppc64le these days, so the user sooner
or later runs into a crash there when not explicitely specifying
the "-cpu POWER8" option to QEMU (which is currently using POWER7
for the "pseries" machine by default). Due to this reason, the
linux-user target already switched to POWER8 a while ago (see commit
de3f1b9841). Since the softmmu target
of course has the same problem, we should switch there to POWER8 for
the newer machine types, too.

If the user passes an alias name and a property to -cpu, QEMU fails to
find the CPU definition and exits.
$ qemu-system-ppc64 -cpu POWER8E,compat=power7
qemu-system-ppc64: Unable to find sPAPR CPU Core definition
This happens because spapr_get_cpu_core_type() passes the full string from
the command line (i.e. "POWER8E,compat=power7") to ppc_cpu_lookup_alias(),
instead of the alias name piece only (i.e. "POWER8E").
The fix is to pass model_pieces[0] to ppc_cpu_lookup_alias().

The current code uses pa_features_206 for POWERPC_MMU_2_06, and
for everything else, it uses pa_features_207. This is bad in some
cases because there is also a "degraded" MMU version of ISA 2.06,
called POWERPC_MMU_2_06a, which should of course use the flags for
2.06 instead. And there is also the possibility that the user runs
the pseries machine with a POWER5+ or even 970 processor. In that
case we certainly do not want to set the flags for 2.07, and rather

Add a generic loader to QEMU which can be used to load images or set
memory values.
Internally inside QEMU this is a device. It is a strange device that
provides no hardware interface but allows QEMU to monkey patch memory
specified when it is created. To be able to do this it has a reset
callback that does the memory operations.
This device allows the user to monkey patch memory. To be able to do
this it needs a backend to manage the datas, the same as other
memory-related devices. In this case as the backend is so trivial we
have merged it with the frontend instead of creating and maintaining a
seperate backend.

This is not mandated as long as MSI routing is not used
(because the kernel sets a default irqchip routing table).
However once MSI routing gets used (for VIRTIO-PCI vhost for
example), the first call to KVM_SET_GSI_ROUTING overrides the
kernel default irqchip table.
If no routing entry exists for the GSI, any IRQFD signaling for
this GSI will fail.

ATA8-APT defines the state transitions for both a host controller and
for the hardware device during the lifecycle of a DMA transfer, in
section 9.7 "DMA command protocol."
One of the interesting tidbits here is that when a device transitions
from DDMA0 ("Prepare state") to DDMA1 ("Data_Transfer State"), it can
choose to set either BSY or DRQ to signal this transition, but not both.
as ide_sector_dma_start is the last point in our preparation process
before we begin the real data transfer process (for either AHCI or BMDMA),
this is the correct transition point for DDMA0 to DDMA1.
I have chosen !BSY && DRQ for QEMU to make the transition from DDMA0 the
most obvious.
