2023-07-20acpi: Move ECAM resource below PNP0C02 device in a common placeArthur Heymans
From the Linux documentation (Documentation/PCI/acpi-info.rst): [6] PCI Firmware 3.2, sec 4.1.2: If the operating system does not natively comprehend reserving the MMCFG region, the MMCFG region must be reserved by firmware. The address range reported in the MCFG table or by _CBA method (see Section 4.1.3) must be reserved by declaring a motherboard resource. For most systems, the motherboard resource would appear at the root of the ACPI namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and the resources in this case should not be claimed in the root PCI bus’s _CRS. The resources can optionally be returned in Int15 E820 or EFIGetMemoryMap as reserved memory but must always be reported through ACPI as a motherboard resource. So in order for the OS to use ECAM MMCONF over legacy PCI IO configuration, a PNP0C02 HID device needs to reserve this region. As no AMD platform has this defined in DSDT this fixes Linux using legacy PCI IO configuration over MMCONF. Tianocore messes with e820 table in such a way that it prevents Linux from using PCIe ECAM. This change fixes that problem.

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.

2021-04-21ChromeOS: Use CHROMEOS_NVS guardKyösti Mälkki
Replace CONFIG(CHROMEOS) with CONFIG(CHROMEOS_NVS) for cases where the conditional and dependency are clearly about the presence of an ACPI NVS table specified by vendorcode. For couple locations also CONFIG(HAVE_ACPI_TABLES) changes to CONFIG(CHROMEOS_NVS). This also helps find some of the CONFIG(CHROMEOS) cases that might be more FMAP and VPD related and not about ChromeOS per-se, as suggested by followup works.

2021-01-27ACPI: Add top-level ASLKyösti Mälkki
Objects that are created with acpigen need to be declared with External () for the generation of dsdt.asl to pass iasl without errors. There are some objects that are common to all platforms, and some that should be declared only conditionally. Having a top-level ASL helps to achieve this.
