The way we currently model the RPU subsystem is of quite
limited use. In addition to that, it causes problems for
KVM and for GDB debugging.
Make the RPU optional by adding a has_rpu property and
default to having it disabled.
This changes the default setup from having the RPU to not
longer having it.

The Aspeed AST2400 integrates a set of 14 I2C/SMBus bus controllers
directly connected to the APB bus. They can be programmed as master or
slave but the propopsed model only supports the master mode.
On the TODO list, we also have :
- improve and harden the state machine.
- bus recovery support (used by the Linux driver).
- transfer mode state machine bits. this is not strictly necessary as
it is mostly used for debug. The bus busy bit is deducted from the
I2C core engine of qemu.
- support of the pool buffer: 2048 bytes of internal SRAM (not used
by the Linux driver).

Switch to adding compat properties incrementaly instead of
completly overwriting compat_props per machine type.
That removes data duplication which we have due to nested
[PC|SPAPR]_COMPAT_* macros.
It also allows to set default device properties from
default foo_machine_options() hook, which will be used
in following patch for putting VMGENID device as
a function if ISA bridge on pc/q35 machines.

The 32-bit ARM Linux kernel booting ABI requires that r0 is 0
when calling the kernel image. A bug in commit 10b8ec73e6
meant that for boards which use the write_board_setup hook (which
means "highbank", "midway", "raspi2" and "xilinx-zynq-a9") we
were incorrectly skipping the "clear r0" instruction in the
mini-bootloader. Use the right offset in the "add lr, pc, #n"
instruction so that we return from the board-setup code to the
correct place.

This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed. This replacement improves the readability and
understandability of code.
For example,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

The new machine is a thin layer over the AST2400 ARM926-based SoC[1].
Between the minimal machine and the current SoC implementation there is
enough functionality to boot an aspeed_defconfig Linux kernel to
userspace. Nothing yet is specific to the Palmetto's BMC (other than
using an AST2400 SoC), but creating specific machine types is preferable
to a generic machine that doesn't match any particular hardware.

In preparation for future ARM virt machine types, this patch creates
an abstract type for all ARM machines. The current machine type in
QEMU (i.e. "virt") is renamed to "virt-2.6", whose naming scheme is
similar to other architectures. For the purpose of backward compatibility,
"virt" is converted to an alias, pointing to "virt-2.6". With this patch,
"qemu -M ?" lists the following virtual machine types along with others:
virt QEMU 2.6 ARM Virtual Machine (alias of virt-2.6)
virt-2.6 QEMU 2.6 ARM Virtual Machine

Both platform and PCI vfio drivers create a "slow", I/O memory region
with one or more mmap memory regions overlayed when supported by the
device. Generalize this to a set of common helpers in the core that
pulls the region info from vfio, fills the region data, configures
slow mapping, and adds helpers for comleting the mmap, enable/disable,
and teardown. This can be immediately used by the PCI MSI-X code,
which needs to mmap around the MSI-X vector table.
This also changes VFIORegion.mem to be dynamically allocated because
otherwise we don't know how the caller has allocated VFIORegion and
therefore don't know whether to unreference it to destroy the
MemoryRegion or not.

Support ARM big-endian ELF files in system-mode emulation. When loading
an elf, determine the endianness mode expected by the elf, and set the
relevant CPU state accordingly.
With this, big-endian modes are now fully supported via system-mode LE,
so there is no need to restrict the elf loading to the TARGET
endianness so the ifdeffery on TARGET_WORDS_BIGENDIAN goes away.
