Subject: [PATCH 01/24] make: fix where dependency *.d are stored.

In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'.  It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.

As a hack, we also touch two sources for generated *.hex files.  Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

Subject: [PATCH 02/24] make: load only required dependency files.

The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.

This patch fixes this by
  - loading precise list of .d files made from *.o and *.mo.
  - specifying explicit list of required dependency info files for
     *.hex autogenerated sources.

Note that Makefile still includes some .d in root directory by including
"*.d".

Subject: [PATCH 03/24] piix: Document coreboot-specific RAM size config
 register

The existing i440fx initialization code sets a PCI config register that
isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is
DRAMC (DRAM Control) and has nothing to do with the RAM size.

This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa
because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to
get the RAM size from QEMU, but I couldn't find out why coreboot did
that. I assume it was a mistake, and the original code was supposed to
be reading the DRB[0-7] registers (offsets 0x60-0x67).

Document that coreboot-specific register offset in a macro and a
comment, for future reference.

Subject: [PATCH 04/24] pc: Use PC_COMPAT_* for CPUID feature compatibility

Now we can use compat_props to keep CPUID feature compatibility, using
the boolean QOM properties for CPUID feature flags.

This simplifies the compatibility code, and reduces duplication between
pc_piix.c and pc_q35.c.

Subject: [PATCH 09/24] pc: Eliminate pc_common_machine_options()

All TYPE_PC_MACHINE subclasses call pc_common_machine_options().
TYPE_PC_MACHINE can simply initialize the common options on class_init
directly.

Subject: [PATCH 10/24] pc: Eliminate pc_default_machine_options()

The only PC machines that didn't call pc_default_machine_options() were
isaps and xenfv. Both were already overwriting max_cpus, and only isapc
was not overwriting hot_add_cpu.

After making isapc set hot_add_cpu to NULL, we can move the
pc_default_machine_options() code the PC common class_init.

Subject: [PATCH 11/24] pc: Use PCMachineState for pc_cmos_init() argument

pc_cmos_init() already expects a PCMachineState object, there's no point
in upcasting it to MachineState before calling the function.

While doing it, reorder the arguments so PCMachineState is the first
function argument.

Subject: [PATCH 18/24] pci: allow 0 address for PCI IO/MEM regions

Some kernels program a 0 address for io regions. PCI 3.0 spec
section 6.2.5.1 doesn't seem to disallow this.

based on patch by Michael Roth <mdroth@linux.vnet.ibm.com>

Add pci_allow_0_addr in MachineClass to conditionally
allow addr 0 for pseries, as this can break other architectures.

This patch allows to hotplug PCI card in pseries machine, as the first
added card BAR0 is always set to 0 address.

This as a temporary hack, waiting to fix PCI memory priorities for more
machine types...

Subject: [PATCH 20/24] acpi: avoid potential uninitialized access to
 cpu_hp_io_base

When building QEMU with Mingw64 toolchain I see a warning

 CC    x86_64-softmmu/hw/i386/acpi-build.o
  hw/i386/acpi-build.c: In function 'acpi_build':
  hw/i386/acpi-build.c:1138:9: warning: 'pm.cpu_hp_io_base' may be used uninitialized in this function [-Wmaybe-uninitialized]
           aml_append(crs,
           ^
  hw/i386/acpi-build.c:1666:16: note: 'pm.cpu_hp_io_base' was declared here
       AcpiPmInfo pm;
                  ^

In acpi_get_pm_info() some of the fields are pre-initialized
to 0, but this one was missed.

Subject: [PATCH 22/24] smbios: remove dependency on x86 e820 tables

Current smbios builds type 19 table from e820, which is x86 specific.
This patch removes smbios' dependency on e820 by passing an array
of memory area to smbios_get_tables().

To share smbios among different architectures, this patch moves SMBIOS
code (smbios.c and smbios.h) from x86 specific folders into new
hw/smbios directories. As a result, CONFIG_SMBIOS=y is defined in
x86 default config files.
