According to the MIPS Malta Developement Platform User's Manual, the
i8259 interrupt controller is supposed to be connected to the hardware
IRQ0, and the CBUS UART to the hardware interrupt 2.
In QEMU they are both connected to hardware interrupt 0, the CBUS UART
interrupt being wrong. This patch fixes that. It should be noted that
the irq array in QEMU includes the software interrupts, hence
env->irq[2] is the first hardware interrupt.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,

Split serial.c into serial.c, serial.h and serial-isa.c. While being at
creating a serial.h header file move the serial prototypes from pc.h to
the new serial.h. The latter leads to s/pc.h/serial.h/ in tons of
boards which just want the serial bits from pc.h

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init
functions in the future;
- Let machine initialization forward the init arguments to other
functions more easily.
This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

Functions pci_vga_init() and pci_cirrus_vga_init() are declared
in pc.h. That prevents other platforms (e.g. sPAPR) to use them.
This patch is to create one new file vga-pci.h and move the
declarations to vga-pci.h, so that they can be shared by
all platforms. This patch also cleans up on all platforms.

This patch adds two things. First it allows QEMU to distinguish between
regular powerdown and S4 powerdown. Later separate QMP notification will
be added for S4 powerdown. Second it allows S3/S4 states to be disabled
from QEMU command line. Some guests known to be broken with regards to
power management, but allow to use it anyway. Using new properties
management will be able to disable S3/S4 for such guests.
Supported system state are passed to a firmware using new fw_cfg file.
The file contains 6 byte array. Each byte represents one system
state. If byte at offset X has its MSB set it means that system state
X is supported and to enter it guest should use the value from lowest 3
bits.

The patch adds definitions of some hardware addresses and uses these
definitions.
It also replaces the type of all addresses from signed to unsigned values.
This is only a cosmetic change because addresses are unsigned values,
the functions called also expect unsigned values,
and we need no sign extension here.

This patch switches pc s3 suspend over to the new infrastructure.
The cmos_s3 qemu_irq is killed, the new notifier is used instead.
The xen hack goes away with that too, the hypercall can simply be
done in a notifier function now.
This patch also makes the guest actually stay suspended instead
of leaving suspend instantly, so it is useful for more than just
testing whenever the suspend/resume cycle actually works.

HPET legacy emulation will require control over the PIT IRQ output. To
enable this, add support for an alternative IRQ output object to the PIT
factory function. If the isa_irq number is < 0, this object will be
used.
This also removes the IRQ number property from the PIT class as we now
use a generic GPIO output pin that is connected by the factory function.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

Commit 5632ae46d5 passes the address
of i8259 to qemu_irq_proxy. i8259 is an auto variable with undefined
value outside of mips_malta_init.
This made the interrupt proxy unusable: either QEMU crashes, or
the interrupt handler was not called.
Ethernet for example no longer worked with MIPS Malta.
v2:
While v1 used a static variable for i8259, this patch introduces
a qdev for the malta machine. i8259 is now part of the device status.
This is a minimal qdev implementation to keep the patch small.

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.

Nothing prevented IRQ sharing on the ISA bus in principle. Not all
boards supported this, neither each and every card nor driver and OS.
Still, there existed valid IRQ sharing scenarios, (at least) two of them
can also be found in QEMU: >2 PC UARTs and the PREP IDE buses.
So remove this artificial restriction from our ISA model.
