3e8f019be7 hw/mips: Have mips_cpu_create_with_clock() take an endianness argument
mips_cpu_create_with_clock() creates a vCPU. Pass it the vCPU

805659a895 hw/mips/cps: Set the vCPU 'cpu-big-endian' property
Have the CPS expose a 'cpu-big-endian' property so it can
set it to the vCPUs it creates.
Note, since the number of vCPUs created is dynamic, we can
not use QOM aliases.

7e6b5497ea hw/char: Extract serial-mm
hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

  # grep -r -e "select SERIAL" | grep -v SERIAL_
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"
  include/hw/char/serial-mm.h:#include "hw/char/serial.h"
  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
  hw/char/serial.c:#include "hw/char/serial.h"
  hw/char/serial-isa.c:#include "hw/char/serial.h"

similar.

e052944a96 hw/pci/pci: Remove multifunction parameter from pci_create_simple_multifunction()
There is also pci_create_simple() which creates non-multifunction PCI
devices. Accordingly the parameter is always set to true when a multi
function PCI device is to be created.

The reason for the parameter's existence seems to be that it is used in the
internal PCI code as well which is the only location where it gets set to
false. This one usage can be replaced by trivial code.

Remove this redundant, error-prone parameter.

dc96009afd hw/mips/malta: Fix the malta machine on big endian hosts
Booting a Linux kernel with the malta machine is currently broken
on big endian hosts. The cpu_to_gt32 macro wants to byteswap a value
for little endian targets only, but uses the wrong way to do this:
cpu_to_[lb]e32 works the other way round on big endian hosts! Fix
it by using the same ways on both, big and little endian hosts.

9d8299bf93 hw/mips/malta: Fix minor dead code issue
Coverity points out (in CID 1508390) that write_bootloader has
some dead code, where we assign to 'p' and then in the following
line assign to it again. This happened as a result of the
refactoring in commit cd5066f861.

Fix the dead code by removing the 'void *v' variable entirely and
instead adding a cast when calling bl_setup_gt64120_jump_kernel(), as
we do at its other callsite in write_bootloader_nanomips().

1953dfa80e hw/mips/malta: Set PIIX4 IRQ routes in embedded bootloader
Linux kernel expects the northbridge & southbridge chipsets
configured by the BIOS firmware. We emulate that by writing
a tiny bootloader code in write_bootloader().

Upon introduction in commit 5c2b87e34d ("PIIX4 support"),
the PIIX4 configuration space included values specific to
the Malta board.

Set the Malta-specific IRQ routing values in the embedded
bootloader, so the next commit can remove the Malta specific
bits from the PIIX4 PCI-ISA bridge and make it generic
(matching the real hardware).

9f81e43f10 hw/mips/malta: Trace FPGA LEDs/ASCII display updates
The FPGA LEDs/ASCII display is mostly used by the bootloader
to show very low-level debug info. QEMU connects its output
to a character device backend, which is not very practical
to correlate with ASM instruction executed, interrupts or
MMIO accesses. Also, the display discard the previous states.

To ease bootloader debugging experience, add a pair of trace
events. Such events can be analyzed over time or diff-ed
between different runs.

6233a13859 mips/malta: pass RNG seed via env var and re-randomize on reboot
As of the kernel commit linked below, Linux ingests an RNG seed
passed as part of the environment block by the bootloader or firmware.
This mechanism works across all different environment block types,
generically, which pass some block via the second firmware argument. On
malta, this has been tested to work when passed as an argument from
U-Boot's linux_env_set.

As is the case on most other architectures (such as boston), when
booting with `-kernel`, QEMU, acting as the bootloader, should pass the
RNG seed, so that the machine has good entropy for Linux to consume. So
this commit implements that quite simply by using the guest random API,
which is what is used on nearly all other archs too. It also
reinitializes the seed on reboot, so that it is always fresh.

bd64c210ce hw/mips/malta: turn off x86 specific features of PIIX4_PM
QEMU crashes trying to save VMSTATE when only MIPS target are compiled in
  $ qemu-system-mips -monitor stdio
  (qemu) migrate "exec:gzip -c > STATEFILE.gz"
  Segmentation fault (core dumped)

It happens due to PIIX4_PM trying to parse hotplug vmstate structures
which are valid only for x86 and not for MIPS (as it requires ACPI
tables support which is not existent for ithe later)

Issue was probably exposed by trying to cleanup/compile out unused
ACPI bits from MIPS target (but forgetting about migration bits).

Disable compiled out features using compat properties as the least
risky way to deal with issue.
