pseries: Populate "/chosen/linux,stdout-path" in the FDT

There is a device tree property "/chosen/linux,stdout-path" which indicates
which device should be used as stdout - ie. "the console".

Currently we don't specify anything, which means both firmware and Linux...

pseries: Remove hcalls callback

For forgotten historical reasons, PAPR hypercalls for specific virtual IO
devices (oh which there are quite a number) are registered via a callback
in the VIOsPAPRDeviceInfo structure.

This is kind of ugly, so this patch instead registers hypercalls from...

pseries: Add a routine to find a stable "default" vty and use it

In vty_lookup() we have a special case for supporting early debug in
the kernel. This accepts reg == 0 as a special case to mean "any vty".

We implement this by searching the vtys on the bus and returning the...

pseries: Check we have a chardev in spapr_vty_init()

If qemu is run like:

qemu-system-ppc64 -nodefaults -device spapr-vty

We end up in spapr_vty_init() with dev->chardev == NULL. Currently
that leads to a segfault because we unconditionally call
qemu_chr_add_handlers()....

pseries: Default reg for vty should be SPAPR_VTY_BASE_ADDRESS

In commit b4a78527359a4540d84d4cdf629d01cbb262f698 ("Place pseries vty
devices at addresses more similar to existing machines"), we changed the
default reg for the vty to 0x30000000, however we didn't update the default...

pseries: Allow kernel's early debug output to work

The PAPR specification defines a virtual TTY/console interface for guest
OSes to use via the H_PUT_TERM_CHAR and H_GET_TERM_CHAR hypercalls. There
can be multiple virtual ttys, so these take a "termno" parameter. This...

spapr: proper qdevification

Right now the spapr devices cannot be instantiated with -device,
because the IRQs need to be passed to the spapr_*_create functions.
Do this instead in the bus's init wrapper.

This is particularly important with the conversion from scsi-disk...

spapr: prepare for qdevification of irq

Restructure common properties for sPAPR devices so that IRQ definitions
can be added in one place.

Add (virtual) interrupt to PAPR virtual tty device

Now that we have implemented the PAPR "xics" virtualized interrupt
controller, we can add interrupts in PAPR VIO devices. This patch adds
interrupt support to the PAPR virtual tty/console device.

Implement the bus structure for PAPR virtual IO

This extends the "pseries" (PAPR) machine to include a virtual IO bus
supporting the PAPR defined hypercall based virtual IO mechanisms.

So far only one VIO device is provided, the vty / vterm, providing
a full console (polled only, for now)....
