f00b337525 soc/intel/xeon_sp: make CPX ramstage.h common for CPX, SKX
CB:41106 revealed that mb/intel/cedarisland already sets FSP-S UPD (see
CB:40735) while the required includes are still missing in CPX. Buildbot
did not fail because `ramstage.c` never was (implicitly) included.

Fix this problem by making SKX/CPX share a common ramstage header for
now by moving the one from SKX.

Test: Build cedarisland_crb

76cedd2c29 acpi: Move ACPI table support out of arch/x86 (3/5)
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 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

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].

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.

a1b15172d7 create stdio.h and stdarg.h for {,v}snprintf
Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files.
When these headers don't line up with C Standard Library,
it causes problems.

Create stdio.h and stdarg.h header files.  Relocate snprintf
into stdio.h and vsnprintf into stdarg.h from string.h.
Chain include these header files from string.h, since coreboot
doesn't care so much about the legacy POSIX location of these
functions.

Also move va_* definitions from vtxprintf.h into stdarg.h where
they belong (in POSIX).  Just use our own definitions regardless
of GCC or LLVM.

Add string.h header to a few C files which should have had it
in the first place.

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.
