Alexander Graf d1e256fe47 PPC: E500: Use MAS registers instead of internal TLB representation
The natural format for e500 cores to do TLB manipulation with are the MAS
registers. Instead of converting them into some internal representation
and back again when the guest reads them, we can just keep the data
identical to the way the guest passed it to us.

The main advantage of this approach is that we're getting closer to being
able to share MMU data with KVM using shared memory, so that we don't need
to copy lots of MMU data back and forth all the time. For this to work
however, another patch is required that gets rid of the TLB union, as that
destroys our memory layout that needs to be identical with the kernel one.

Alexander Graf 5de6b46db5 PPC: mpc8544ds: Add hypervisor node
When running a PPC guest with KVM that can do PV operations, we need
to indicate the guest which instructions to use for a hypercall and
that it is running as KVM guest.

This logic was available on openbios based machines already. This patch
also adds said functionality to the mpc8544ds machine.

Alexander Graf b0fb84236d PPC: E500: Implement reboot controller
When Linux reboots an e500 VM, it writes to a magic register in the
"global-utilities" device indicated by the device tree. We were not
emulating that device so far, rendering the VM reboot-less.

This patch implements that device with only the reboot functionality
implemented and adds it to the device tree. With this patch applied,
I can successfully reboot a -M mpc8544ds VM.

Alexander Graf d461e3b929 PPC: fix mpc8544ds pci default devices
After the Qdev'ification of the MPC8544DS board and PCI bus, the internal
PCI bus name changed from "pci" to "pci.0". Reflect this change in the
search for that bus.

This patch enables networking on e500 guests again.

Alexander Graf 3b989d499e PPC: Make MPC8544DS emulation work w/o KVM
The MPC8544DS board emulation was only used with KVM so far, so some
parts of the code didn't provide proper values for non-KVM execution.

This patch makes the machine work without KVM enabled. To actually use
this, you also need proper e500v2 MMU emulation.

Aurelien Jarno 409dbce54b load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.

This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.

The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

Markus Armbruster 07caea315a Fix pci_add nic not to exit on bad model
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC.  When MODEL is unknown or "?", this prints to stderr
and terminates the program.

Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure.  Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.

Bonus bug fix: we now check for qdev_init() failing there.

Gerd Hoffmann d176c495b6 qdev-ify virtio-blk.
First user of the new drive property.  With this patch applied host
and guest config can be specified separately, like this:

  -drive if=none,id=disk1,file=/path/to/disk.img
  -device virtio-blk-pci,drive=disk1

You can set any property for virtio-blk-pci now.  You can set the pci
address via addr=.  You can switch the device into 0.10 compat mode
using class=0x0180.  As this is per device you can have one 0.10 and one
0.11 virtio block device in a single virtual machine.

Old syntax continues to work.  Internally it does the same as the two
lines above though.  One side effect this has is a different
initialization order, which might result in a different pci address
being assigned by default.

Long term plan here is to have this working for all block devices, i.e.
once all scsi is properly qdev-ified you will be able to do something
like this:

  -drive if=none,id=sda,file=/path/to/disk.img
  -device lsi,id=lsi,addr=<pciaddr>
  -device scsi-disk,drive=sda,bus=lsi.0,lun=<n>
