2024-01-24soc/*: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

2022-06-24src/soc: Get rid of most src/soc/Kconfig filesMartin Roth
Most of the src/soc/Kconfig files are only there for AMD and Intel to load the main SoC Kconfig files before any common files. That can be done in src/Kconfig instead. Moving the loads to the lower level allows the removal of all but the Intel soc/Kconfig file, which can be removed in a follow-on patch.

2021-11-10Rename ECAM-specific MMCONF KconfigsShelley Chen
Currently, the MMCONF Kconfigs only support the Enhanced Configuration Access mechanism (ECAM) method for accessing the PCI config address space. Some platforms have a different way of mapping the PCI config space to memory. This patch renames the following configs to make it clear that these configs are ECAM-specific: - NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT - MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT - MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS - MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER - MMCONF_LENGTH --> ECAM_MMCONF_LENGTH Please refer to CB:57861 "Proposed coreboot Changes" for more details.

2021-10-26cpu/x86: Introduce and use `CPU_X86_LAPIC`Felix Held
With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

2021-10-25cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCsFelix Held
All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

2021-07-02src: Introduce `ARCH_ALL_STAGES_X86`Angel Pons
Introduce the `ARCH_ALL_STAGES_X86` Kconfig symbol to automatically select the per-stage arch options. Subsequent commits will leverage this to allow choosing between 32-bit and 64-bit coreboot where all stages are x86. AMD Picasso and AMD Cezanne are the only exceptions to this rule: they disable `ARCH_ALL_STAGES_X86` and explicitly set the per-stage arch options accordingly.

2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).

2020-10-30x86: Add a minimal example SoC along with a boardNico Huber
The min86 example SoC code along with the example mainboard should serve as a minimal example how a buildable x86 SoC code base can look like. This can serve, for instance, as a basis to add new SoCs to coreboot. Starting with a buildable commit should help with the review of the actual code, and also avoid any regressions when common coreboot code changes. As the example code itself is build-tested, it should advance with coreboot and can't rot like documentation might. It also serves as a check what APIs need to be implemented with the default Kconfig settings.
