2024-07-25soc/amd: add SoC-specific root_complex.c to SMMFelix Held
The PSP code introduced in a following patch needs both SoC-specific functions get_iohc_info and get_iohc_non_pci_mmio_regs to also be available in SMM, so add those compilation units to the corresponding target.

2024-07-25soc/amd/*/root_complex: introduce and use domain_iohc_info structFelix Held
Instead of implementing the functions get_iohc_misc_smn_base and get_iohc_fabric_id in the SoC code, move those functions to the common AMD code, and implement get_iohc_info in the SoC code that returns a pointer to and the size of a SoC-specific array of domain_iohc_info structs that contains the info needed by the common code instead. This allows to iterate over the domain_iohc_info structs which will be used in a later patch to find the PSP MMIO base address in both ramstage and smm.

2024-05-12vc/amd/opensil: introduce common mpio/chip.h header fileFelix Held
The chip drivers in the devicetree use the path where the corresponding chip.h file resides both to include this chip.h file in the static.c generated by util/sconfig from the devicetree and also for the names of the chip config and chip ops struct. To be able to build a SoC using either the MPIO chip driver from the openSIL stub or from the actual openSIL glue code without needing different devicetree files for the different cases, introduce a common MPIO chip.h file that then includes the correct MPIO header file. The chip config and ops structures also need to be renamed to take this change into account. Thanks to Matt for pointing out how to make the path to the actual MPIO chip.h file configurable via a Kconfig setting. This allows overriding this path from site-local without the need to have any reference to site-local in the upstream code.

2024-01-11soc/amd/common/acpi: factor out common MADT codeFelix Held
The acpi_fill_madt implementation from the Genoa PoC also works for the other AMD SoCs that select SOC_AMD_COMMON_BLOCK_DATA_FABRIC_DOMAIN, so factor out this function to the common AMD ACPI code and change those other SoCs to use the new common functionality instead of having their own implementations. The old code on the single-domain SoCs used the GNB_IO_APIC_ADDR base address to create the MADT entry for the additional IOAPIC in the root complex. The new code iterates over all domains and looks for a resource with the IOMMU_IOAPIC_IDX index in each domain and if it finds it, it creates an MADT entry for that IOAPIC. This resource is created earlier in the boot process when the non-PCI resources are read from the IOHC registers and reported to the allocator.

2023-12-16vc/amd/opensil: add _POC suffix to SOC_AMD_OPENSIL_GENOAFelix Held
The openSIL code for the Genoa SoC is only a proof of concept, so change the name of the Kconfig option to include this code in the build from SOC_AMD_OPENSIL_GENOA to SOC_AMD_OPENSIL_GENOA_POC to clarify that this is code that isn't intended or ready to be productized.

2023-12-16soc/amd/genoa: rename to genoa_pocFelix Held
Even though this SoC is called 'Genoa', the openSIL implementation and the corresponding coreboot integration is only a proof of concept that isn't fully featured, has known limitations and bugs, and is not meant for or ready to being productized. Adding the proof of concept suffix to the name should point this out clearly enough so that no potential customer could infer that this might be a fully functional and supported implementation which it is not.
