We can tell the guest the frequency of its time base through fwcfg.
However, we tell it a different value from the speed tb actually runs
at. Let's fix it and make the tbfreq initialization and the fwcfg exposure
use the same values.

Better support for systems with multiple PCI root buses
FW cfg interface for more robust pci programming in BIOS

At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root. As we add support for
multiple PCI roots, that may no longer be the case. This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters. NICs created new-style, with
-device can of course be put anywhere.

Mac OS X requires a second uninorth register set to be mapped a few
bytes above the first one. Let's just expose it to make it happy.
Signed-off-by: Alexander Graf <agraf@suse.de>
Mac OS X expects the uninorth control register set to contain one
register that always reads back what it writes in. Expose that.
This is just a temporary hack. Eventually, we want to expose the
uninorth (/uni-n in device tree) as a separate QOM device.

Support in fwcfg has been around for exposure of the clock-frequency
CPU property. OpenBIOS reads it, we just never exposed it.
Since Mac OS X is very picky about its clock frequency values, let's
just take a known good value and always expose that.

Currently, for qemu-system-ppc64, the default machine type is 'mac99'.
The mac99 machine is not being actively maintained, and represents a
bizarre hybrid of components that never actually existed as a real system.
This patch changes the default machine to 'pseries', which is actively
maintained and works well with most modern ppc64 Linux distributions as a
guest.

On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.
This went unnoticed, because they used to boot at the same location our flash
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.
Set the initial IP to something reasonable for -M mac99.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

It follows convention of how they are set on real machines,
both ide and dma ones are increased
