Peter Maydell af9277e69d hw/versatile_pci: Drop unnecessary vpb_pci_config_addr()
Drop the vpb_pci_config_addr() function -- it is unnecessary since
the size of the memory regions means the hwaddr is always within
the 24 bit size. (This function was probably a leftover from when
read/write functions were called with absolute addresses rather
than relative ones.)

Peter Maydell 89a32d32fb versatile_pci: Expose PCI memory space to system
The VersatilePB's PCI controller exposes the PCI memory space to the
system via three regions controlled by the mapping control registers.
Implement this so that guests can actually use MMIO-BAR PCI cards.

Peter Maydell a2bff788d2 arm/realview: Fix mapping of PCI regions
Fix the mapping of the PCI regions for the realview board, which were
all incorrect. (This was never noticed because the Linux kernel
doesn't actually include a PCI driver for the realview boards.)

Peter Maydell 7468d73ac9 versatile_pci: Implement the PCI controller's control registers
The versatile_pci PCI controller has a set of control registers which
handle the mapping between PCI and system address spaces. Implement
these registers (though for now they have no effect since we don't
implement mapping PCI space into system memory at all).

The most natural order for our sysbus regions has the control
registers at the start, so move all the others down one.

Peter Maydell 66a96d7018 versatile_pci: Implement the correct PCI IRQ mapping
Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile
board, since we weren't swizzling IRQs based on the slot number.

Since this change would otherwise break any uses of PCI on Linux kernels
which have an equivalent bug (since they have effectively only been
tested against QEMU, not real hardware), we implement a mechanism
for automatically detecting those broken kernels and switching back
to the old mapping. This works by looking at the values the kernel
writes to the PCI_INTERRUPT_LINE register in the config space, which
is effectively the interrupt number the kernel expects the device
to be using.

Peter Maydell cd93dbf375 versatile_pci: Update to realize and instance init functions
Update the Versatile PCI controller to use a realize function rather
than SysBusDevice::init. To reflect the fact that the 'realview_pci'
class is taking most of its implementation from 'versatile_pci' (and
to make the QOM casts work) we make 'realview_pci' a subclass of
'versatile_pci'.

Peter Maydell 5fb8084f31 versatile_pci: Expose PCI I/O region on Versatile PB
Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments.

This change removes the only currently implemented difference
between the realview-pci and versatile-pci models; however there
are other differences in not-yet-implemented functionality, so we
retain the distinction between the two device types.

Nicholas Bellinger af60314291 vhost: Add vhost_commit callback for SeaBIOS ROM region re-mapping
This patch follows MST's recommendation to move checks for
vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations
from MemoryListener->region_[add,del]() -> vhost_set_memory() into
final MemoryListener->commit() -> vhost_commit() callback.

It addresses the case where virtio-scsi vq ioport RAM re-mapping
to read-only SeaBIOS ROM triggers a cpu_physical_memory_map()
NIL MemoryRegionSection pointer failure.

Also save vhost_dev->mem_changed_[start,end]_addr values in
vhost_set_memory() for final ranges_overlap checks.  (Thanks Paolo!)

Configure to use the DTC submodule to build libfdt when no system libfdt

DTC has no out-of-tree build capability, so the configure will symlink

and pass in all the needed DTC arguments to make out of tree build happen.
Ideally we fix the DTC make to support out of tree, but did it this way to
