2020-04-10Replace DEVICE_NOOP with noop_(set|read)_resourcesNico Huber
`.read_resources` and `.set_resources` are the only two device operations that are considered mandatory. Other function pointers can be left NULL. Having dedicated no-op implementations for the two mandatory fields should stop the leaking of no-op pointers to other fields.

2020-04-10Drop unnecessary DEVICE_NOOP entriesNico Huber
Providing an explicit no-op function pointer is only necessary for `.read_resources` and `.set_resources`. All other device-operation pointers are optional and can be NULL.

2020-04-07soc/xeon_sp: add configs to use common/gpio diverMaxim Polyakov
Allow the use of the common/gpio driver to create Lewisburg PCH pad configurations for server motherboards with Skylake-SP processors. This patch should only be applied after adding Lewisburg PCH definitions to the soc/intel/xeon_sp code [1].

2020-04-07soc/intel/xeon_sp: Add Lewisburg defs for common/gpio driverMaxim Polyakov
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: [*] page 39, Intel(R) C620 Series Chipset Platform Controller Hub (PCH) Datasheet, May 2019.

2020-04-02Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`Nico Huber
These two identifiers were always very confusing. We're not filling and injecting generators. We are filling SSDTs and injecting into the DSDT. So drop the `_generator` suffix. Hopefully, this also makes ACPI look a little less scary.

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.

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.
