Blue Swirl 603987488c PPC64: Partial fix to Linux crash: revert to old devfn
Before 2e29bd0478, Uni-North host and AGP
bridge were using the same devfn, 11 << 3. The net effect was that only
AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP.

Some of the later crashes happened due to NULL pointer dereferences generated
by 07b7d05377 and insufficient return value
checks.

Disable host device and revert AGP to 11 << 3.

Blue Swirl c364c974d9 PCI: make duplicate devfn allocation fatal
Only two callers of pci_create_simple/pci_register_device bothered
to check the return value. Other cases were prone to crashing with
spurious NULL pointer dereferences.

Make QEMU exit with an error message when devfn is attempted to
be duplicated, also applies to case when the bus is full. Remove
checks.

Stefan Weil 4e9df06acc eepro100: Fix boot ROM support
* Rename pxe-eepro100.bin to pxe-i82559er.bin.
  The other devices supported by eepro100.c need
  additional pxe boot ROM images.
* Call rom_add_option during initialisation.
  The code won't work with two or more different
  eepro100 devices, because it only adds one option
  ROM, but this use case is perhaps never needed.

Using this patch, model=i82559er at least works partially.
For full support, more eepro100 patches are needed
(will follow later, can be fetched from ar7 branch
of QEMU).

Stefan Weil 038eaf82c8 serial: Add interface to set reference oscillator frequency
Many (most?) serial interfaces have a programmable
clock which provides the reference frequency ("baudbase").
So a fixed baudbase which is only set once can be wrong.

omap1.c is an example which could use the new interface
to change baudbase when the programmable clock changes.
ar7 system emulation (still not part of standard QEMU)
is similar to omap and already uses serial_set_frequency.

Isaku Yamahata e822a52a81 pci: make pci configuration transaction more accurate.
This patch sorts out/enhances pci code to track pci bus topology
more accurately.
- Track host bus bridge with pci domain number. Although the
  current qemu implementation supports only pci domian 0 yet.
- Track pci bridge parent-child relationship.
When looking down from pci host bus for pci sub bus, be aware of
secondary bus/subordinate bus.
Thus pci configuration transaction is more accurately emulated.

This patch adds new member to PCIBus to track pci bus topology.
Since qdev already tracks down bus relationship, those new member
wouldn't be necessary.
However it would be addressed later because not all the pci device

Later a structures declared in pci_host.h, PCIHostState, will be used.
However pci_host.h doesn't allow to include itself easily. This patches
addresses it.

pci_host.h includes functions which are instantiated in .c by including
pci_host.h with typedefing pci_addr_t.
pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio
or target_phys_addr_t for mmio in .c file.
That prevents from including pci_host.h to use PCIHostState because of
requiring type, pci_addr_t.

Its purpose to include is to instantiate io function for mmio or ioio
depending on which pci host bridge requires ioio or mmio.
To avoid including code, we always instantiate both version.
