The original code defines a named object for the resource template but
then returns the resource template object itself; the resulted output
is like below:
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()
{
WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
0x0000, // Granularity
0x0000, // Range Minimum
0x00FF, // Range Maximum
0x0000, // Translation Offset
0x0100, // Length
,, )
......
})
Return (ResourceTemplate ()
{
WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
0x0000, // Granularity
0x0000, // Range Minimum
0x00FF, // Range Maximum
0x0000, // Translation Offset
0x0100, // Length
,, )
......
})
}
So the named object "RBUF" is actually useless. The more natural way
is to return RBUF instead, or simply drop RBUF definition.
Choose the latter one to simplify the code.

According to ACPI spec, _ADR should be used for device on a bus that
has a standard enumeration algorithm, but not for device which is on
system bus and must be enumerated by OSPM. And it is not recommended
to contain both _HID and _ADR in a single device.
See ACPI 6.3, section 6.1, top of page 343:
A device object must contain either an _HID object or an _ADR object,
but should not contain both.

acpi_data_push uses g_array_set_size to resize the memory size. If there
is no enough contiguous memory, the address will be changed. If we use
the old value, it will assert.
qemu-kvm: hw/acpi/bios-linker-loader.c:214: bios_linker_loader_add_checksum:
Assertion `start_offset < file->blob->len' failed.`
This issue only happens in building SRAT table now but here we unify the
pattern for other tables as well to avoid possible issues in the future.

It fixes/add missing _PXM object for non mapped CPU (x86)
and missing fdt node (virt-arm).
It ensures that possible_cpus contains complete mapping if
numa is enabled by the time machine_init() is executed.
As result non completely mapped CPUs:
1) appear in ACPI/fdt blobs
2) QMP query-hotpluggable-cpus command shows bound nodes for such CPUs
3) allows to drop checks for has_node_id in numa only code,
reducing number of invariants incomplete mapping could produce
4) moves fixup/implicit node init from runtime numa_cpu_pre_plug()
(when CPU object is created) to machine_numa_finish_init() which
helps to fix [1, 2] and make possible_cpus complete source
of numa mapping available even before CPUs are created.

A bunch of fixes that missed the release.
Most notably we are reverting shpc back to enabled by default state
as guests uses that as an indicator that hotplug is supported
(even though it's unused). Unfortunately we can't fix this
on the stable branch since that would break migration.

Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.
Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.
Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

Add a board level property to the virt board which will
enable EL2 on the CPU if the user asks for it. The
default is not to provide EL2. If EL2 is enabled then
we will use SMC as our PSCI conduit, and report the
virtualization support in the GICv3 device tree node
and the ACPI tables.
