For builds with MAINBOARD_HAS_CHROMEOS=y but CHROMEOS=n, there
is reduced dsdt.aml size and reduced GNVS allocation from cbmem.
More importantly, it's less error-prone when the OperationRegion
size is not hard-coded inside the .asl files.

There is a common place where acpigen generates these,
so the declarations for the OperationRegions should be
centralized too.

Objects that are created with acpigen need to be declared
with External () for the generation of dsdt.asl to pass
iasl without errors.
There are some objects that are common to all platforms,
and some that should be declared only conditionally.
Having a top-level ASL helps to achieve this.

The layout of GNVS has expectation for a fixed size
array for chromeos_acpi_t. This allows us to reduce
the exposure of <chromeos/gnvs.h>.
If chromeos_acpi_t was the last entry in struct global_nvs
padding at the end is also removed.
If device_nvs_t exists, place a properly sized reserve for
chromeos_acpi_t in the middle.
Allocation from cbmem is adjusted such that it matches exactly
the OperationRegion size defined inside the ASL.

Add support for the Intel LPIT table to support reading Low Power Idle
Residency counters by the OS. On platforms supporting S0ix sleep states
there can be two types of residencies:
* CPU package PC10 residency counter (read from MSR via FFH interface)
* PCH SLP_S0 assertion residency counter (read via memory mapped
interface)
With presence of one or both of these counters in the LPIT table, Linux
dynamically adds the corresponding attributes to the cpuidle sysfs
interface, that can be used to read the residency timers:
* /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
* /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
The code in src/acpi implements generic LPIT support. Each SoC or
platform has to implement `acpi_fill_lpit` to fill the table with
platform-specific LPI state entries. This is done in this change for
soc/intel/common, while being added as its own compilation unit, so SoCs
not yet using common acpi code (like Skylake) can use it, too.
Reference:
https://uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf
Test: Linux adds the cpuidle sysfs interface; Windows with s0ix_enable=1
boots without crashing with an INTERNAL_POWER_ERROR.
- Windows and Linux tested on google/akemi together with CB:49046
- Linux tested on clevo/cml-u, supermicro/x11ssmf together with CB:49046

Allocation now happens prior to device enumeration. The
step cbmem_add() is a no-op here, if reached for some
boards. The memset() here is also redundant and becomes
harmful with followup works, as it would wipe out the
CBMEM console and ChromeOS related fields without them
being set again.

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as
reset register in FADT. How unsurprising. We might as well use that
information to automatically fill in the FADT accordingly. So, do it.
To avoid having x86-specific code under arch-agnostic `acpi/`, create a
new optional `arch_fill_fadt` function, and override it for x86 systems.
Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of

In the initial DPTF refactor, the scope of the TCPU device was
incorrectly set as \_SB, instead of \_SB.PCI0. However, because of the
way that the acpi_inject_dsdt() callback currently works (it injects
contents before the dsdt.aml file), the Scope where the TCPU
device lives (\_SB.PCI0) doesn't exist yet. Therefore, to avoid playing
games with *when* things are defined in the DSDT, switch to defining all
of the DPTF devices in the SSDT.

As per ACPI spec, GpioIo does not have any polarity associated with
it. Linux kernel uses `active_low` argument within GPIO _DSD property
to allow BIOS to indicate if the corresponding GPIO should be treated
as active low. Thus, if GPIO has active high polarity or if it does
not have any polarity associated with it, then the `active_low`
argument is supposed to be set to 0.
Having a `polarity` field in acpi_gpio seems confusing because GPIOs
might not always have polarity associated with them. Example, in case
of DMIC-select GPIO where 0 means select DMIC0 and 1 means select
DMIC1, there is no polarity associated with the GPIO. Thus, it would
be clearer for mainboard to use macros without having to specify a
particular polarity. In order to enable mainboards to provide GPIO
information without polarity for GpioIo usage, this change also adds
`ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

The current implementation of acpi_dp_write() frees the node after it
has written it.
If the structure contains a ACPI_DP_TYPE_CHILD then a recursive call to
acpi_dp_write() frees the child and then frees it again when returning
from the call. This results in a double free.
Split the implementation into two steps, one that ones and one that
frees. This is easier to understand and fixes the bug.
Note: This likely has no effect in coreboot since it doesn't seem to
have a proper free() implementation. But it might gain one one day.

This change adds support for generating the device descriptor that
corresponds to the UARTSerialBusV2() ACPI macro.
The resulting ACPI code for ACPI_UART_RAW_DEVICE(115200, 64) is:
UartSerialBusV2 (0x0001C200, DataBitsEight, StopBitsOne,
0x00, LittleEndian, ParityTypeNone, FlowControlNone,
0x0040, 0x0040, "\\_SB.PCI0.UAR2",
0x00, ResourceConsumer, , Exclusive)

There have been changes to the way device properties are supported
in Linux[1] and Windows[2] which add flexibilty:
- non-standard UUIDs can be used instead of only ACPI_DP_UUID
- support for multiple different packages within the _DSD that
associate different properties with unique UUIDs.
To handle this I extracted the part that does the write of UUID and
properties to a separate function and defined a new PACKAGE type
which has the custom UUID as a name and can be used the same way that
child properties are today.
For example a PCIe root port for a USB4 port has a standard property
indicating the USB4 reference, and then two custom properties which
are defined for different attributes.
Example code:
/* Create property table */
acpi_dp *dsd = acpi_dp_new_table("_DSD");
acpi_dp_add_reference(dsd, "usb4-port", usb4_path);
/* Add package for hotplug */
acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4");
acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1);
acpi_dp_add_package(dsd, pkg);
/* Add package for external port info */
pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389");
acpi_dp_add_integer(pkg, "ExternalFacingPort", 1);
acpi_dp_add_package(dsd, pkg);
/* Write all properties */
acpi_dp_write(dsd);
Resulting ACPI:
Scope (\_SB.PCI0.TRP0)
{
Name (_DSD, Package ()
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
Package ()
{
Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA }
},
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),

{
Package () { "HotPlugSupportInD3", One }
},

in order to provide functions for upcoming changes:
acpigen_write_return_op(): Return an operator.
acpigen_write_if_lequal_op_op(): Check if 2 operands are equal.
acpigen_get_package_op_element(): Read an element from a package

This change uses the previously added SoundWire definitions to provide
functions that generate ACPI Device Properties for SoundWire
controllers and codecs.
A SoundWire controller driver should populate
`struct soundwire_controller` and pass it to
soundwire_gen_controller(). This will add all of the defined master
links provided by the controller.
A SoundWire codec driver should populate the necessary members in
struct soundwire_codec and pass it to soundwire_gen_codec().
Several properties are optional and depend on whether the codec itself
supports certain features and behaviors.
The goal of this interface is to handle all of the properties defined
in the SoundWire Discovery and Configuration Specification Version
1.0 so that controller and codec drivers do not need to all have code
for writing standard properties.
Both of these functions also provide a callback method for adding
custom properties that are not defined by the SoundWire DisCo
Specification. These properties may be required by OS drivers but are
outside of the scope of the SoundWire specification itself.
This code is tested with controller, codec, and mainboard
implementations in subsequent commits.

This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 1/5 which moves .c files from arch/x86 to
acpi/.
The only acpi files that are still retained under arch/x86 are:
a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there
are some assumptions in there about SMM which will have to be resolved
if this file needs to be moved to common code.
b. acpi_bert_storage.c/bert_storage.h: This file is currently written
specifically with x86 in mind. So, not moving the file for now.
Motivation for this change: Not all stages on Picasso SoC are targeted
for the same architecture. For example, verstage (if runs before
bootblock) will be targeted for non-x86. This makes it difficult to
add device tree to verstage which would be required to get to SoC
configs from the tree. This is because the device tree on x86
platforms currently contains a lot of devices that require ACPI
related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so
on). Hence, this change removes all ACPI table support out of
arch/x86.
