c62c98a884 soc/intel/xeon_sp: Early programming of ACPI bar
ACPI bar was not programmed previously for which is needed to enable SMI's and
to check SMI status registers. The architecture of Lewisburg PCH is very
similar to SunrisePoint PCH thus we can use code from soc/intel/skylake.

TEST=build for Tiogapass and check ACPI base. Log message will now show
pmbase=501 (bit 0 is enable) instead of 0. Check by reading and writing
to io port 0x500.

6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

The removed lines are:
-       fmt.Fprintln(f, "/* This file is part of the coreboot project. */")

182d7bae47 soc/intel/xeon_sp: Add Lewisburg defs for common/gpio driver
Adds definitions that allow to use the common GPIO driver to configure
the Lewisburg PCH pads. Using the GPIO configuration from common/gpio,
unlike the FSP-style definitions from Intel RefCode [1] definitions,
is more understandable and makes the motherboards code much cleaner.
In addition, we can use utilities, such as inteltool, to analyze the
configuration of proprietary firmware to add support for new server
motherboards with Skylake-SP processors.

The pin layout in this patch corresponds to the pinctrl driver in the
Linux kernel v4.14 for the Lewisburg PCH GPIO controller [2].

[1] https://designintools.intel.com/product_p/stlgrn45.htm
[2] drivers/pinctrl/intel/pinctrl-lewisburg.c

These changes are in accordance with the documentation:

    (PCH) Datasheet, May 2019. Document Number: 336067-007US.

2e410757ef soc/intel/xeon_sp: Add basic Cooperlake-SP support
This adds barebones support.

What works:
* Linux kernel boots fine
* SIRQ and PCH interupts work fine (only in IOAPIC mode)
* PCH devices are usable

What doesn't:
* MP init is not there yet, only 1 CPU is up
* SMM is not supported
* GPIO is not available
* All IIO and extended bus numbers enumeration is not yet available
* Warm reset flow is untested
* MRC cache save/load

TEST=boots into Linux

662da6cf7b soc/intel/xeon_sp: Refactor code to allow for additional CPUs types
Refactor the code and split it into Xeon common and CPU-specific code.
Move most Skylake-SP code into skx/ and keep common code in the current
folder.

This is a preparation for future work that will enable next
generation server CPU.

TEST=Tested on OCP Tioga Pass. There does not seem to be degradation
of stability as far as I could tell.

1c6d8a9cf4 soc: Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

8f89549d3c soc/intel: Add Intel Xeon Scalable Processor support
This patch adds support for Intel Xeon-SP.

This patch is developed and verified with Skylake Scalable
Processor, which is a processor in Xeon-SP family. The code
is expected to be reusable for future geneations of Xeon-SP
processors, and will be updated with smaller targeted
patches accordingly, to add support for additional Xeon-SP
processors, to add features, and to improve the code base.

The Skylake-SP FSP is based on FSP 2.0. The FSP is a
proof-of-concept build. The binary is not shared in public,
when this patch is upstreamed.
