63626b1a4a sb/intel/common: Create a common PCH finalise implementation
The common finalise code is used by bd82x6x, Lynx Point, and Ibex Peak.

Lynx Point now benefits from being able to write-protect the flash chip.

For Lynx Point, writing the SPI OPMENU now happens in ramstage, as done
in bd82x6x.

Tested on an ASRock H81M-HDS (Lynx Point). When write-protection is
configured, flashrom reports all flash regions as read-only, and does
not manage to alter the contents of the flash chip.

Also tested on an ASUS P8H61-M LX (Cougar Point). Everything seems to
work as before.

31312b21d1 sb/intel/i82801gx: Use common Intel SMM code
Use the common Intel code to set up smm and the smihandler. This is
expected to break S3 resume and other smihandler related
functionality as this code is meant to be used with
CONFIG_SMM_TSEG. Platforms (i945, pineview, x4x) using this
southbridge will adapt the CONFIG_SMM_TSEG codepath in subsequent
patches.

Tested on Intel D945GCLF, still boots fine but breaks S3 resume
support because it hangs on SMI.

boards and sb/intel/bd82x6x, so share a common function between them.

The common implementation might only need minor alterations to support
them.

Tested on an ASRock H81M-HDS and Google Peppy (variant of Slippy). No
issues arose from this patch.

Some Windows and BSD quirk handling went into the util copies. We always

HAVE_INTEL_FIRMWARE is used to enable certain options that rely on a valid
Inter Flash Descriptor to exist. It does *not* identify platforms or boards
that are capable of running in descriptor mode if it's valid.
Refine the help text to make this clear.

Introduce a new option INTEL_DESCRIPTOR_MODE_CAPABLE that does simply
declare that IFD is supported by the platform. Select this value everywhere
instead of the HAVE_INTEL_FIRMWARE and default HAVE_INTEL_FIRMWARE to
y if INTEL_DESCRIPTOR_MODE_CAPABLE is selected.

Move the QEMU Q35 special case (deselection of HAVE_INTEL_FIRMWARE) to
the mainboard directory.

aade90e68d nb/intel/gm45: Use common code for SMM in TSEG
This makes i82801ix use the common smm southbridge code to set up smm
relocation and smi handler setup. This is needed in this change for the
the smm relocation code relies on some southbridge functions provided
in the common code. Some of the old code is kept for the Q35 qemu
target.

This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.

Currently SMRR msr's are not set on model_1067x and model_6fx since this needs
the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled
properly in the subsequent parallel mp init patchset.

Tested on Thinkpad X200: boots and going to and resuming from S3 still
works fine.

04d2601426 sb/intel/common/firmware: Enable me_cleaner for Nehalem
Recent patches in coreboot have fixed the freeze issues related to the
use of me_cleaner on Nehalem.

However, at least on the Lenovo X201, with me_cleaner some PCIe devices
(like the SATA and USB controllers) disappear. In particular, setting
the AltMeDisable bit ("-S" or "-s" flag) makes them disappear
completely, while unsetting it makes them disappear only during cold
boots.

This kind of behaviour was already observed by Youness Alaoui on the
Purism Librem laptops ([1]), and it seems related to some required
board-specific PCIe configuration in the ME's MFS partition.

For this reason, on the Lenovo X201, "-w EFFS" has been added to the
me_cleaner arguments, which whitelists the MFS-equivalent partition for
ME generation 2. This fixes all the issues, and the PCIe devices work as
expected.

364f2e10cb sb/intel/common/firmware: Use the -S flag of me_cleaner
The -S flag of me_cleaner, in addition to the standard code removal,
sets the the AltMeDisable bit (ME 6.x-10.x) or the HAP bit (ME 11.x),
which asks Intel ME to stop the execution after the hardware
initialization.

This should bring some advantages:
 * The state of Intel ME can be easily obtained by reading the Current
    Operation Mode register to trigger specific adjustments in the
    raminit (as already done in bd82x6x)
 * Intel ME falls into a more defined state, instead of being in a
    generic "Image Failure"
 * Hopefully, less code is run by Intel ME, as the execution should
    stop before even trying to load additional modules

Tested on:
 * Nehalem, Sandy Bridge and Ivy Bridge (Nicola Corna)
 * Broadwell, Skylake and Kabylake (Youness Alaoui)

If needed, the -S flag can be removed or integrated with other
board-specific options by overriding CONFIG_ME_CLEANER_ARGS.

02c997122f src/sb/intel/common/spi.c: Adapt and link in romstage
Based on Nicola Corna's work.

This allows for CONFIG_CONSOLE_SPI_FLASH to be used, which writes the
console output to the SPI flash.

TESTED to still work in ramstage on x220 (correctly writes MRC CACHE),
the option CONFIG_CONSOLE_SPI_FLASH compiles for targets using the
common Intel SPI code (untested though).

e8620146d9 sb/intel/common/pirq_gen: Rework generating pin-route tables
This creates a pin-route matrix first and then generates the ACPI
entries based on that. This approach has the advantage of being
simpler (no need for checks on double entries) and requiring less
access to the pci config space.

A few thing that are also fixed:
* Don't declare DEFAULT_RCBA redundantly.
* Only loop over PCI devices on bus 0
* Add a license header to rcba_pirq.c
* Remove inappropriate use of typedefs
* Fix the pin field: needs to be a byte
* Fix the source field: it should either be a byte or a path
(according to Advanced Configuration and Power Interface Specification
rev 2.0c)

851dde8255 drivers/spi: reduce confusion in the API
Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:

- Remove spi_xfer_two_vectors() which was fusing transactions to
  accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
  utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
  will trigger an error as these controllers can't support the api.

Commit d2d2aef6a3 (sb/intel/{bd82x6,ibexpeak}: Move RCBA macros to a
common location) makes some platforms use the wrong OIC register defi-
nition. It was extended to 16-bit in the corporate version of ICH10.
So let's give the new size and location a new name: EOIC (extended OIC).

This only touches the systems affected by the mentioned change. Other
platforms still need to be adapted before they can use the common RCBA
definitions.

9d8be5a857 sb/intel/common: Automatically generate ACPI PIRQ
Based on change I2b5d68adabf0840162c6f295af8d10d8d3007a34
(sb/intel/common: Add function to automatically generate ACPI PIRQ).

This adds functionality to generate PIRQ ACPI tables automatically based
on the chipset registers.

Mapping of PCI interrupt pin to PIRQ is done by the chipset-specific
intel_common_map_pirq() function, an shared implementation of which is
provided for the bd82x6x, i82801, i89xx, ibexpeak and lynxpoint
chipsets.
