2023-09-06soc/amd: correctly report I2C controller state in ACPIFelix Held
Instead of reporting all I2C controllers in the system as enabled in the corresponding ACPI device's _STA method, report the I2C devices that are disabled in the devicetree as disabled in the corresponding _STA method too. This is done by returning the contents of the STAT variable inside each device's scope in the DSDT that have a default value of 0 (device not present/disabled). For all enabled and hidden I2C devices i2c_acpi_fill_ssdt gets called which then writes 0xf (device enabled and visible) or 0xb (device enabled, but hidden) to the STAT name inside the same scope, but in the SSDT. This object in the SSDT will then override the default in the DSDT resulting in the _STA method returning the correct status of each device. The code was inspired by commit 7cf9c7451808 ("soc/amd/*: Fix UART ACPI device status"). TEST=On Mandolin all I2C controllers are disabled and with this patch none shows up in the Windows 10 device manager. When enabling an I2C controller in the devicetree for testing, it shows up again in the Windows device manager.

2023-08-09soc/amd/*: Fix UART ACPI device statusMatt DeVillier
Prior to commit d1c0f958d198 ("acpi: Call acpi_fill_ssdt() only for enabled devices"), uart_inject_ssdt() was used to set the ACPI status (_STA) for both enabled and disabled devices. The aforementioned commit limited it to being called only on enabled devices, which left disabled devices without any _STA method at all -- which the OS assumes means that the device is present and enabled. To fix this, create the _STA method in the UART asl code for each port, and set the return value to a name variable (STAT) which defaults to 0 (not present/disabled). Then, have uart_inject_ssdt() set STAT to present and enabled (0xF) for UARTs actually present on the board. TEST=build/boot google/skyrim (frostflow), dump ACPI tables, and verify that _STA returns 0xF only for UARTs enabled in devicetree.

2023-07-07soc/amd/*/globalnvs,nvs: remove deprecated & unused CBMC field from GNVSFelix Held
Commit cde4f3b2790d ("acpi/gnvs.c: Drop unused pointer to the cbmem console") removed writing the coreboot memory console pointer to the GNVS and kept the CBMC field as reserved. Since those fields aren't needed any more and there are no dependencies on the absolute position of the different fields in GNVS as long as both GNVS definitions on the C and the ASL side match, remove the deprecated and unused CBMC field from the GNVS structs.

Use the new common AMD code that gets the usable non-fixed MMIO windows from the data fabric MMIO decode registers and generate the PCI0 _CRS ACPI code based on those regions. For a more detailed description see the corresponding patch that changes the Picasso code to use this new code. In contrast to the Picasso code, this change will drop the unneeded _STA method inside the PCI0 scope which wasn't present in Picasso's ACPI code before it got replaced by the SSDT that gets generated by amd_pci_domain_fill_ssdt.
