APIC Serial Bus pins were removed with ICH5 already, so a choice
'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG
0x3 is also not documented since ICH5.
For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was
wrong and ignored as BOOT_CONFIG register emulation was never implemented.
For ICH4 and earlier, the choice to use FSB can be made based on the
installed CPU model but this is now just hardwired to match P4 CPUs of
aopen/dxplplusu.
For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined
and the only possible operation mode there is APIC Serial Bus, which
requires no configuration.

Derived from Broadwell and adapted to follow what soc/intel does. Note
that SERIALIO_UART_CONSOLE is meant to be selected from the mainboards
which expose a SerialIO UART. UART_FOR_CONSOLE also needs to be set in
mainboard Kconfig accordingly.
It is possible that some of the UART configuration steps in bootblock
are unnecessary. However, some of the steps turn off power management
features and others are undocumented: omitting them could cause weird
issues.
Finally, add a config file to ensure the code gets build-tested.
Tested on out-of-tree Compal LA-A992P, SerialIO UART 0 can be used to
receive coreboot and SeaBIOS logs.

the conditional and dependency are clearly about the presence of
an ACPI NVS table specified by vendorcode. For couple locations also
CONFIG(HAVE_ACPI_TABLES) changes to CONFIG(CHROMEOS_NVS).
This also helps find some of the CONFIG(CHROMEOS) cases that might
be more FMAP and VPD related and not about ChromeOS per-se, as
suggested by followup works.

Do not use the same name as the non-LP GPIO config. This allows checking
at build-time that a mainboard uses the correct GPIO config format.
Without this commit, there are no build-time errors when using the wrong
format of GPIO config, but there would be undefined behavior at runtime.
Tested by trying to build asrock/b85m_pro4 and hp/folio_9480m after
toggling the `INTEL_LYNXPOINT_LP` Kconfig option (and trimming down the
USB config arrays for asrock/b85m_pro4). In both cases, building failed
because the necessary GPIO config global is not defined, as expected.

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.

Add the missing PM initialization for Lynxpoint-H. There are some small
changes to Lynxpoint-LP, since some register writes are common among
both PCH variants. This is based on version 1.9.1 of reference code.
Remove the `pch_fixups()` function. The DMI configuration is specific to
Lynxpoint-H. It is not valid for Lynxpoint-LP, which does not have DMI.
Tested on Asrock B85M Pro4, still boots. Registers have the new values.

Needed to support build with ACPI_SOC_NVS=n as SMIF object inside
GNVS disappears then.

- Add support for ME Soft Temporary Disable Mode. In this mode, ME
doesn't load its kernel and freezes at Bring UP (BUP) phase. This mode
is saved in ME NVRAM (and thus will remain for next reboots and
poweroffs).
- Add support of new CMOS option for Sandy Bridge and Ivy Bridge
ThinkPads.
HOW TO USE
To disable ME:
1. nvramtool -w me_state=Disabled
2. reboot
To enable it back:
1. nvramtool -w me_state=Normal
2. reboot
To check current status:
intelmetool -m
Tested on ThinkPad X230 and ThinkPad X220.
BACKGROUND
There's no Intel documentation that would explain how this should be
implemented, in public. Working binary sequence for MKHI command to put
ME in Soft Temporary Disable Mode, as well as a way to bring ME out of
it (by writing to H_GS register), was found and published by researchers
from PT Security:
1. To disable ME, BIOS issues the disable command (before End of Post)
and reboots. ME is supposed to be disabled on the next boot after
DID (DRAM Init Done).
My numerous tests show that issuing the command and rebooting is not
enough. If we reboot too early, ME will not be disabled. Apparently,
it is doing something in background after receiving the command. It
works with a delay of 500-1000 ms.
I also tried to dump all known (documented) registers, such as GMES
and HFS, before and during the next 2 seconds after execution of the
disable command to find a possible indication that something's
changed in ME and we're ready to reboot. Found nothing
unfortunately.
2. To enable ME back, host writes value 0x20000000 to H_GS.
PT slides don't contain any more information on it, but my tests
show, that after writing this value, GMES[31:28] is changing from
0x01 (BUP phase) to 0x03 (Policy Module) to 0x06 (Host
Communication). Then, after some more time, fw_init_complete bit of
HFS becomes 1.
This means that ME starts loading its kernel immediately, without
reboot.
On the other hand, Lenovo BIOS clearly perform a reboot after
enabling it (one reboot after saving the settings, then ThinkPad
logo appears, and then one more reboot). I'm assuming we have to
reset too.

- Add Kconfig option to hide the Management Engine Interface device so
the OS doesn't try to access it, if the Management Engine is in an
inoperable mode, e.g. if me_cleaner is used.
- Also hide the MEI if the ME is in Soft Temp Disable mode.

For the moment, these are most not used but become a necessity
for a unified <soc/nvs.h> approach.
They would be required for the implementation of _SWS method
for OSPM to determine the reason for system waking up. The related
hardware registers are present with these platforms.
It's expected that ACPI power-management related GNVS entries are
grouped together to form a single struct in later works.

Create `FIXED_RCBA_MMIO_BASE` and use it everywhere, except in cases
where a pointer cast would be necessary. Instances in Sandy Bridge MRC
code were left as-is intentionally, so as not to collide with another
cleanup patch train.
Tested with BUILD_TIMELESS=1, these boards remain identical:
- Asus P8Z77-V LX2
- Packard Bell MS2290
