If you specify a known backend but it isn't compiled in, or failed to
initialize, you get a simple warning and the "none" backend as a
fallback, and QEMU runs happily:
$ qemu-system-x86_64 -audiodev id=audio,driver=dsound
audio: Unknown audio driver `dsound'
audio: warning: Using timer based audio emulation
...
Instead, QEMU should fail to start:
$ qemu-system-x86_64 -audiodev id=audio,driver=dsound
audio: Unknown audio driver `dsound'
$

Support for the unix socket has existed both in BSD and Linux for the
longest time, but not on Windows. Since Windows 10 build 17063 [1],
the native support for the unix socket has come to Windows. Starting
this build, two Win32 processes can use the AF_UNIX address family
over Winsock API to communicate with each other.

The Device Control Registers (DCR) of on-SoC devices are accessed by
software through the use of the mtdcr and mfdcr instructions. These
are converted in transactions on a side band bus, the DCR bus, which
connects the on-SoC devices to the CPU.
Ideally, we should model these accesses with a DCR namespace and DCR
memory regions but today the DCR handlers are installed in a DCR table
under the CPU. Instead, introduce a little device model wrapper to hold
a CPU link and handle registration of DCR handlers.
The DCR device inherits from SysBus because most of these devices also
have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier
to install the device model in the overall SoC.

This moves all the code previously done in the ppc405ep_init() routine
under ppc405_soc_realize(). We can also adjust the number of banks now
that we have control on ppc4xx_sdram_init().

It is an initial model to start QOMification of the PPC405 board.
QOM'ified devices will be reintroduced one by one. Start with the
memory regions, which name prefix is changed to "ppc405".
Also, initialize only one RAM bank. The second bank is a dummy one
(zero size) which is here to match the hard coded number of banks in
ppc405ep_init().

We will use this machine as a base to define the ref405ep and possibly
the PPC405 hotfoot board as found in the Linux kernel.

User creatable root ports are being parented by the 'peripheral' or the
'peripheral-anon' container. This happens because this is the regular
QOM schema for sysbus devices that are added via the command line.
Let's make this QOM hierarchy similar to what we have with default root
ports, i.e. the root port must be parented by the pnv-root-bus. To do
that we change the qom and bus parent of the root port during
root_port_realize(). The realize() is shared by the default root port
code path, so we can remove the code inside pnv_phb_attach_root_port()
that was adding the root port as a child of the bus as well.
After all that, remove pnv_phb_attach_root_port() and create the root
port explictly in the 'default_enabled()' case of pnv_phb_realize().

We have 2 helpers that amends the QOM and parent bus of a given object,
repectively. These 2 helpers are called together, and not by accident.
Due to QOM internals, doing an object_unparent() will result in the
device being removed from its parent bus. This means that changing the
QOM parent requires reassigning the parent bus again.
Create a single helper called pnv_parent_fixup(), documenting some of
the QOM specifics that we're dealing with the unparenting/parenting
mechanics, and handle both the QOM and the parent bus assignment.
Next patch will make use of this function to handle a case where we need
to change the QOM parent while keeping the same parent bus assigned
beforehand.

Given that powernv9 and powernv10 uses the same pnv-phb backend, the
logic to allow user created pnv-phbs for powernv10 is already in place.
Let's flip the switch.

The function assumes that we're always dealing with a PNV9_CHIP()
object. This is not the case when the pnv-phb device belongs to a
powernv10 machine.
Change pnv_phb4_get_pec() to be able to work with PNV10_CHIP() if
necessary.

The PHB4 backend relies on a link with the corresponding PEC element.
This is trivial to do during machine_init() time for default devices,
but not so much for user created ones.
pnv_phb4_get_pec() is a small variation of the function that was
reverted by commit 9c10d86fee "ppc/pnv: Remove user-created PHB{3,4,5}
devices". We'll use it to determine the appropriate PEC for a given user
created pnv-phb that uses a PHB4 backend.
This is done during realize() time, in pnv_phb_user_device_init().
