These interfaces manage the power domains that guest devices are
assigned to and are used to power on/off devices. Currently we
only utilize 1 power domain, the 'live-insertion' domain, which
automates power management of plugged/unplugged devices, essentially
making these calls no-ops, but the RTAS interfaces are still required
by guest hotplug code and PAPR+.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of
these interfaces.

This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

When specifying a non-existing file with the "-bios" parameter, QEMU
complained that it "could not find LPAR rtas". That's obviously a
copy-n-paste bug from the code which loads the spapr-rtas.bin, it
should complain about a missing firmware file instead.
Additionally the error message was printed with hw_error() - which
also dumps the whole CPU state. However, this does not make much
sense here since the CPU is not running yet and thus the registers
only contain zeroes. So let's use error_report() here instead.
And while we're at it, let's also bail out if the firmware file
had zero length.

spapr_pci.c contains a number of expressions of the form (uval == -1) or
(uval != -1), where 'uval' is an unsigned value.
This mostly works in practice, because as long as the width of uval is
greater or equal than that of (int), the -1 will be promoted to the
unsigned type, which is the expected outcome.
However, at least for the cases where uval is uint32_t, this would break
on platforms where sizeof(int) > 4 (and a few such do exist), because then
the uint32_t value would be promoted to the larger int type, and never be
equal to -1.
This patch fixes these errors. The fixes for the (uint32_t) cases are
necessary as described above. I've made similar fixes to (uint64_t) and
(hwaddr) cases. Those are strictly theoretical, since I don't know of any
platforms where sizeof(int) > 8, but hey, it's not that hard so we might
as well be strictly C standard compliant.

The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().
