972d9f2cce arch/x86: consolidate HPET base address definitions
Both the HPET_BASE_ADDRESS define from arch/x86/include/arch/hpet.h and
the HPET_ADDRESS Kconfig option define the base address of the HPET MMIO
region which is 0xfed00000 on all chipsets and SoCs in the coreboot
tree. Since these two different constants are used in different places
that however might end up used in the same coreboot build, drop the
Kconfig option and use the definition from arch/x86 instead. Since it's
no longer needed to check for a mismatch of those two constants, the
corresponding checks are dropped too.

7f8c737fe9 acpi/acpi: use read32p instead of pointer dereferencing
Using read32p to get the contents of the first 4 bytes of the HPET MMIO
region instead of a pointer dereference should clarify what's done in
that piece of code.

e9665959ed treewide: Remove "ERROR: "/"WARN: " prefixes from log messages
Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with

  's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

4e9bb3308e Rename ECAM-specific MMCONF Kconfigs
Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address
space.  Some platforms have a different way of mapping the PCI config
space to memory.  This patch renames the following configs to
make it clear that these configs are ECAM-specific:

- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

details.

d47946e750 acpi: Generate power resource name instead of default "PRIC"
This change uses a static 8-bit counter in
`acpi_device_add_power_res()` to generate the name of power resource
object rather using a default name "PRIC". This makes it easier to
identify which power resource Linux kernel logs are referring to. If
more than 256 power resources are used in the system, then the counter
will wrap around to 0. However, 256 seems to be a large enough number
for the power resource count.

TEST=Verified that Power Resources are named as expected:
```
dmesg | grep ACPI | grep PR
[    0.550921] ACPI: Power Resource [PR00] (on)
[    0.869960] ACPI: Power Resource [PR01] (on)

f7dbf4afd6 acpi: drop weak implementation of acpi_soc_get_bert_region
acpi_soc_get_bert_region only gets called when a chipset's Kconfig
selects the ACPI_BERT option in which case the chipset code needs to
implement this function. In the case of acpi_soc_get_bert_region not
being implemented, but ACPI_BERT being selected for a chipset this patch
changes the behavior from never generating a BERT ACPI table to a build
error which is more obvious and easier to catch.

eff0713dfc src/acpi: Add APEI EINJ support
This adds full EINJ support with trigger action tables. The actual
error injection functionality is HW specific. Therefore, HW specific
code should call acpi_create_einj with an address where action table
resides. The default params of the action table are filled out by the
common code.  Control is then returned back to the caller to modify or
override default parameters. If no changes are needed, caller can
simply add the acpi table. At runtime, FW is responsible for filling
out the action table with the proper entries. The action table memory
is shared between FW and OS. This memory should be marked as reserved
in E820 table.

Tested on Deltalake mainboard.  Boot to OS, load the EINJ driver (
modprobe EINJ) and verify EINJ memory entries are in /proc/iomem.
Further tested by injecting errors via the APEI file nodes.  More
information on error injection can be referenced in the latest ACPI
spec.

This commit introduces set of package closing functions corresponding

opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.

ae7ac8a723 ACPI: Separate ChromeOS NVS in ASL
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.

cf246d5166 ACPI: Add top-level ASL
Objects that are created with acpigen need to be declared

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.

f0a44ae0eb acpi,soc/intel/common: add support for Intel Low Power Idle Table
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

834b3ecd7c cbfs: Simplify load/map API names, remove type arguments
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.

b20aac0721 soc/intel/skl,acpi/acpigen: convert global CPPC package to local one
Move the global CPPC package \GCPC to the first logical core CP00 and
adapt the reference in the other cores. This is cleaner and avoids
confusion.
