David Gibson 9d52e9079d Add POWER7 support for ppc
This adds emulation support for the recent POWER7 cpu to qemu.  It's far
from perfect - it's missing a number of POWER7 features so far, including
any support for VSX or decimal floating point instructions.  However, it's
close enough to boot a kernel with the POWER7 PVR.

Edgar E. Iglesias d63cb48db9 powerpc: Make the decr interrupt type overridable
Make it possible for boards to override the kind of interrupt
to be signaled when the decr timer hits. The 405's signal PIT
interrupts while the 440's signal DECR.

Alexander Graf 45024f094c PPC: Add PV hypercall transport through fw_cfg
On KVM for PPC we need to tell the guest which instructions to use when
doing a hypercall. The clean way to do this is to go through an ioctl
from userspace and passing it on to the guest using the device tree.

So let's do the qemu part here: read out the hypercall and pass it on
to the guest's fw_cfg so openBIOS can read it out and expose it again.

Alexander Graf dc333cd609 PPC: tell the guest about the time base frequency
Our guest systems need to know by how much the timebase increases every second,
so there usually is a "timebase-frequency" property in the cpu leaf of the
device tree.

This property is missing in OpenBIOS.

With qemu, Linux's fallback timebase speed and qemu's internal timebase speed
match up. With KVM, that is no longer true. The guest is running at the same
timebase speed as the host.

This leads to massive timing problems. On my test machine, a "sleep 2" takes
about 14 seconds with KVM enabled.

This patch exports the timebase frequency to OpenBIOS, so it can then put them
into the device tree.

Alexander Graf 0f921197f1 PPC: Use Mac99_U3 type on ppc64
The "Mac99" type so far defines a "U2" based configuration. Unfortunately,
there have never been any U2 based PPC64 machines. That's what the U3 was
developed for.

So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32
machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals
stay the same.

Alexander Graf 73b01960b4 PPC: Make DCR uint32_t
For what I know DCR is always 32 bits wide, so we should also use uint32_t to
pass it along the stacks.

This fixes a warning when compiling qemu-system-ppc64 with KVM enabled, making
it compile without --disable-werror

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.
