When trying to load an ELF file specified via -kernel, we need to
pass load_elf() the ELF machine type corresponding to the CPU we're
booting with, not the one corresponding to the softmmu binary
we happen to be running. (The two are different in the case of
loading a 32-bit ARM ELF file into a 32 bit CPU being emulated
by qemu-system aarch64.) This was causing us to incorrectly fail
to load ELF images in this situation.

QEMU supports firmware names for all devices in the QEMU tree but
some architectures expect some parts of firmware path names in different

This introduces a firmware-pathname-change interface definition.
If some machines needs to redefine the firmware path format, it has
to add the TYPE_FW_PATH_PROVIDER interface to an object that is above
the device on the QOM tree (typically /machine).

As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path()
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.
We could handle suffixes in SLOF (ignored for now) but this would require
serious rework in the node opening code in SLOF, which has no obvious

Some object_property_add_link() callers expect property deletion to
unref the link property object. Other callers expect to manage the
refcount themselves. The former are currently broken and therefore leak
the link property object.
This patch adds a flags argument to object_property_add_link() so the
caller can specify which refcount behavior they require. The new
OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be
unreferenced when the property is deleted.
This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c,
s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c.
Rationale for refcount behavior:
* hw/core/qdev.c
- bus children are explicitly unreferenced, don't interfere
- parent_bus is essentially a read-only property that doesn't hold a
refcount, don't unref
- hotplug_handler is leaked, do unref
* hw/dma/xilinx_axidma.c
- rx stream "dma" links are set using set_link, therefore they
need unref
- tx streams are set using set_link, therefore they need unref
* hw/net/xilinx_axienet.c
- same reasoning as hw/dma/xilinx_axidma.c
* hw/pcmcia/pxa2xx.c
- pxa2xx bypasses set_link and therefore does not use refcounts
* hw/s390x/s390-virtio-bus.c
* hw/virtio/virtio-pci.c
* hw/virtio/virtio-rng.c
* ui/console.c
- set_link is used and there is no explicit unref, do unref

Offset 4 is UARTRSR/UARTECR, not the UARTCR. The UARTCR would be
corrupted if the UARTRSR is ever written. Fix by implementing a correct
model of the UARTRSR/UARTECR register. Reads of this register simply
reflect the error bits in data register. Only breaks can be triggered in
QEMU. With the pl011_can_receive function, we effectively have flow
control between the host and the model. Framing and parity errors simply
don't make sense in the model and will never occur.

Intermittent issues have been seen where no serial input occurs. It
appears the pl011 gets in a state where the rx interrupt never fires
because the rx interrupt only asserts when crossing the fifo trigger
level. The fifo state appears to get out of sync when the pl011 is
re-configured. This combined with the rx timeout interrupt not being
modeled results in no more rx interrupts.
Disabling the fifo is the recommended way to clear the tx fifo in the
TRM (section 3.3.8). The behavior in this case for the rx fifo is
undefined in the TRM, but having fifo contents to be maintained during
configuration changes is not likely expected behavior. Reseting the
fifo state when the fifo size is changed is the simplest solution.
