Factor out acpi_add_fsp_tables from the soc_acpi_write_tables function and move the remaining parts of the soc_acpi_write_tables function to the SoC's acpi.c. This aligns the other family 17h/19h SoCs more with Genoa and only leaves the FSP-specific code in agesa_acpi.c which will be made common in a following patch. I decided against also renaming agesa_acpi.c to acpi_fsp.c, since that would have made the diff less readable and the files get deleted in a following patch anyway.

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.

The latency values in the _CST package override the values in the p_lvl2_lat and p_lvl3_lat FADT fields. In Picasso, Cezanne, Mendocino, Phoenix and Glinda generate_cpu_entries generates the _CST packages for each CPU device. The coreboot code for Stoneyridge doesn't generate _CST packages for the CPU objects, but those are provided via the PSTATE SSDT binaryPI generates and agesa_write_acpi_tables gets and adds to the ACPI tables. The AGESA reference code also sets those two FADT entries to the equivalents of ACPI_FADT_C2_NOT_SUPPORTED and ACPI_FADT_C3_NOT_SUPPORTED so this also matches the AGESA behavior. From the ACPI 6.4 spec: "Values provided by the _CST object override P_LVLx values in P_BLK and P_LVLx_LAT values in the FADT."

2023-01-12soc/amd: Change Morgana codename to PhoenixMartin Roth
Now that the next generation of APUs is officially announced, we can unmask morgana. The chip formerly known as Morgana is actually Phoenix. Surprise! This patch just changes the name across the entire codebase. Note that the fw.cfg file will stay pointing to the 3rdparty/amd_blobs/morgana/psp directory until the amd_blobs_repo is updated.
