On the OpenTitan hardware the resetvec is fixed at the start of ROM. In
QEMU we don't run the ROM code and instead just jump to the next stage.
This means we need to be a little more flexible about what the resetvec
is.
This patch allows us to set the resetvec from the command line with
something like this:
-global driver=riscv.lowrisc.ibex.soc,property=resetvec,value=0x20000400

Furthermore, if we encounter any PCI groups from hostdevs that are marked

If the ZPCI_OP ioctl reports that is is available and usable, then the
underlying KVM host will enable load/store intepretation for any guest
device without a SHM bit in the guest function handle. For a device that
will be using interpretation support, ensure the guest function handle
matches the host function handle; this value is re-checked every time the
guest issues a SET PCI FN to enable the guest device as it is the only
opportunity to reflect function handle changes.
By default, unless interpret=off is specified, interpretation support will
always be assumed and exploited if the necessary ioctl and features are
available on the host kernel. When these are unavailable, we will silently
revert to the interception model; this allows existing guest configurations
to work unmodified on hosts with and without zPCI interpretation support,
allowing QEMU to choose the best support model available.

An abort happens in ohci_frame_boundary() when ohci->done is 0 [1].
``` c
static void ohci_frame_boundary(void *opaque)
{
// ...
if (ohci->done_count == 0 && !(ohci->intr_status & OHCI_INTR_WD)) {
if (!ohci->done)
abort(); <----------------------------------------- [1]
```
This was reported in https://bugs.launchpad.net/qemu/+bug/1911216/,
https://lists.gnu.org/archive/html/qemu-devel/2021-06/msg03613.html, and
https://gitlab.com/qemu-project/qemu/-/issues/545. I can still reproduce it with
the latest QEMU.
This happends due to crafted ED with putting ISO_TD at physical address 0.
Suppose ed->head & OHCI_DPTR_MASK is 0 [2], and we memset 0 to the phyiscal
memory from 0 to sizeof(ohci_iso_td). Then, starting_frame [3] and frame_count
[4] are both 0. As we can control the value of ohci->frame_number (0 to 0x1f,
suppose 1), we then control the value of relative_frame_number to be 1 [6]. The
control flow goes to [7] where ohci->done is 0. Have returned from
ohci_service_iso_td(), ohci_frame_boundary() will abort() [1].
``` c
static int ohci_service_iso_td(OHCIState *ohci, struct ohci_ed *ed)
{
// ...
addr = ed->head & OHCI_DPTR_MASK; // <--------------------- [2]
if (ohci_read_iso_td(ohci, addr, &iso_td)) { // <-------- [3]
// ...
starting_frame = OHCI_BM(iso_td.flags, TD_SF); // <-------- [4]
frame_count = OHCI_BM(iso_td.flags, TD_FC); // <-------- [5]
relative_frame_number = USUB(ohci->frame_number, starting_frame);
// <-------- [6]
if (relative_frame_number < 0) {
return 1;
} else if (relative_frame_number > frame_count) {
// ...
ohci->done = addr; // <-------- [7]
// ...
}
```
As only (afaik) a guest root user can manipulate ED, TD and the physical memory,
this assertion failure is not a security bug.
The idea to fix this issue is to drop ohci_service_iso_td() if ed->head &
OHCI_DPTR_MASK is 0, which is similar to the drop operation for
ohci_service_ed_list() when head is 0. Probably, a similar issue is in
ohci_service_td(). I drop ohci_service_td() if ed->head & OHCI_DPTR_MASK is 0.

pnv_phb3_root_bus_info and pnv_phb4_root_bus_info are missing the
instance_size initialization. This results in accessing out-of-bound
memory when setting 'chip-id' and 'phb-id', and eventually crashes
glib's malloc functionality with the following message:
"qemu-system-ppc64: GLib: ../glib-2.72.3/glib/gmem.c:131: failed to allocate 3232 bytes"
This issue was noticed only when running qtests with QEMU Windows
32-bit executable. Windows 64-bit, Linux 32/64-bit do not expose
this bug though.

spapr->htab is allocated by qemu_memalign(), hence we should use
qemu_vfree() to free it.
