2020-03-26soc/intel/xeon_sp: Add basic Cooperlake-SP supportAndrey Petrov
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 Signed-off-by: Andrey Petrov <anpetrov@fb.com> Change-Id: I7c987badc3c53f16ad178369c7e0906d6596e465 Reviewed-on: https://review.coreboot.org/c/coreboot/+/39713 Reviewed-by: Maxim Polyakov <max.senia.poliak@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-03-26soc/intel/xeon_sp: Configure P2SB BAR in bootblockAndrey Petrov
In order to use early serial output we need to enable P2SB BAR0, because that allows PCR access to PCH registers.

2020-03-26soc/intel/xeon_sp: Refactor code to allow for additional CPUs typesAndrey Petrov
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.

2020-03-25create stdio.h and stdarg.h for {,v}snprintfJoel Kitching
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.

2020-03-18soc: Remove copyright noticesPatrick Georgi
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.

If we don't pretend to have binaries, there is no need to add fake ones. This also fixes building the default config.

2020-03-06soc/intel: Add Intel Xeon Scalable Processor supportJonathan Zhang
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.
