hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.Right now there are many catch-all headers in include/hw/ARCH dependingon cpu.h, and this makes it necessary to compile these files per-target.However, fixing this does not belong in these patches....
cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.Explicitly zero them on reset since they were located beforebreakpoints.
Pass PowerPCCPU to kvmppc_handle_halt().

e500: Replace open-coded loop with qemu_get_cpu()
Since we still need env for ppc-specific fields, obtain it via the newenv_ptr fields to avoid "cpu" name conflicts between CPUState andPowerPCCPU for now.
This fixes a potential issue with env being NULL at the end of the loop...
PPC: e500: fix mpic_iack address
MPIC+0xa0 is IACK for the current CPU. MPIC+0x200a0 is IACK for CPU 0.This fix allows EPR to work with an SMP target.

PPC: e500: Select MPIC v4.2 on ppce500 platform
The compatible string is changed to fsl,mpic on all e500 platforms, toadvertise the existence of BRR1. This matches what the device tree willhave on real hardware.
With MPIC v4.2 max_cpu can be increased from 15 to 32....

PPC: E500: Calculate loading blob offsets properly
We have 3 blobs we need to load when booting the system:
- kernel - initrd - dtb
We place them in physical memory in that order. At least we should.This patch fixes the location calculation up to take any module into...
PPC: e500: Change in-memory order of load blobs
Today, we load
<kernel> <initrd> <dtb>
into memory in that order. However, Linux has a bug where it can onlyhandle the dtb if it's within the first 64MB of where <kernel> starts.
So instead, let's change the order to...
cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using anegative offset. Therefore the field is placed last in CPUState.
Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.
Move common parts of mips cpu_state_reset() to mips_cpu_reset()....
PPC: KVM: set has-idle in guest device tree
On e500mc, the platform doesn't provide a way for the CPU to go idle.
To still not uselessly burn CPU time, expose an idle hypercall to the guestif kvm supports it.

PPC: Bring EPR support closer to reality
We already used to support the external proxy facility of FSL MPICs,but only implemented it halfway correctly.

Move public headers to include/net, and leave private headers in net/.Put the virtio headers in include/net/tap.h, removing the multiple copiesthat existed. Leave include/net/tap.h as the interface for NICs, andnet/tap_int.h as the interface for OS-specific parts of the tap backend....
janitor: do not rely on indirect inclusions of or from qemu-char.h
Various header files rely on qemu-char.h including qemu-config.h ormain-loop.h, but they really do not need qemu-char.h at all (particularlyinteresting is the case of the block layer!). Clean this up, and also...

PPC: E500: Generate dt pci irq map dynamically
Today we're hardcoding the PCI interrupt map in the e500 machine file.Instead, let's write it dynamically so that different machine typescan have different slot properties.

PPC: E500: Move PCI slot information into params
We have a params struct that allows us to expose differences betweene500 machine models. Include PCI slot information there, so we can havedifferent machines with different PCI slot topology.
PPC: e500: pci: Export slot2irq calculation
We need the calculation method to get from a PCI slot ID to its respectiveinterrupt line twice. Once in the internal map function and once whenassembling the device tree.
So let's extract the calculation to a separate function that can be called...
openpic: remove irq_out
The current openpic emulation contains half-ready code for bypass mode.Remove it, so that when someone wants to finish it they can start from aclean state.
openpic: convert to qdev
This patch converts the OpenPIC device to qdev. Along the way itrenames the "openpic" target to "raven" and the "mpic" target to"fsl_mpic_20", to better reflect the actual models they implement.
This way we have a generic OpenPIC device now that can handle...
PPC: e500: Add MSI support
Now that our interrupt controller supports MSIs, let's expose that featureto the guest through the device tree!
mpic: Unify numbering scheme
MPIC interrupt numbers in Linux (device tree) and in QEMU are different,because QEMU takes the sparseness of the IRQ number space into account.
Remove that cleverness and instead assume a flat number space. This makesthe code easier to understand, because we are actually aligned with Linux...
e500: Adding CCSR memory region
All devices are also placed under CCSR memory region.The CCSR memory region is exported to pci device. The MSI interruptgeneration is the main reason to export the CCSR region to PCI device.This put the requirement to move mpic under CCSR region, but logically...
Adding BAR0 for e500 PCI controller
PCI Root complex have TYPE-1 configuration header while PCI endpointhave type-0 configuration header. The type-1 configuration header havea BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pciaddress space to CCSR address space. This can used for 2 purposes: 1)...
PPC: e500: Map PIO space into core memory region
On PPC, we don't have PIO. So usually PIO space behind a PCI bridge isaccessible via MMIO. Do this mapping explicitly by mapping the PIO spaceof our PCI bus into a memory region that lives in memory space....

serial: split serial.c
Split serial.c into serial.c, serial.h and serial-isa.c. While being atcreating a serial.h header file move the serial prototypes from pc.h tothe new serial.h. The latter leads to s/pc.h/serial.h/ in tons ofboards which just want the serial bits from pc.h...

PPC: e500: calculate initrd_base like dt_base
While investigating dtb pad issues, I noticed that initrd_base wasn't takingloadaddr into account the way dt_base was. This seems wrong.
PPC: e500: Only expose even TLB sizes in initial TLB
When booting our e500 machine, we automatically generate a big TLB entryin TLB1 that covers all of the code we need to run in there until the guestcan handle its TLB on its own.
However, e500v2 can only handle MAS1.0 sizes. However, we keep our TLB...
