2023-03-29soc/amd/common/cpu/tsc: factor out family-specific get_pstate_core_freqFelix Held
Factor out the get_pstate_core_freq function from the SoC's acpi.c files to both avoid duplication and to also be able to use the same function in the TSC frequency calculation in a follow-up patch. The family 17h and 19h SoCs use the same frequency encoding in the P state MSRs while the family 1Ah SoCs use a different encoding. The family 15h and 16h SoCs use another encoding, but since this isn't implemented in Stoneyridge's acpi.c, this will be added in a follow-up patch.

Now that all get_pstate_core_power implementations in each SoC's acpi.c file is identical, factor it out into a common implementation. This implementation will also work for Stoneyridge which isn't using the common P state code yet.

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."

In CB:71614 Kyösti pointed out that ACPI_GPE0_BLK is the wrong address to assign to proc_blk_addr; the correct one would be ACPI_CPU_CONTROL. When looking a bit closer into this, it turned out that acpigen_write_processor is generating deprecated AML opcodes, so replace the acpigen_write_processor call with a call to the newly added acpigen_write_processor_device function that also doesn't have the proc_blk_addr and proc_blk_len parameters. The information about the IO port for entering C-states is already written into an SSDT by acpigen_write_CST_package which is likely also the reason why the wrong proc_blk_addr value wasn't noticed for a very long time. TEST=Mandolin still boots Ubuntu 22.04 LTS and Windows 10 and no possibly related errors show up. Linux gets the expected C-state information from the _CST package inside the processor device scope.

Stoneyridge used CONFIG_MAX_CPUS and CONFIG_MAX_CPUS + 1 directly as IOAPIC IDs and Picasso had Kconfig options to configure that, but still used the common SMBus controller code that used CONFIG_MAX_CPUS as ID for the FCH IOAPIC. If a board overrides the PICASSO_FCH_IOAPIC_ID Kconfig option to a value that isn't CONFIG_MAX_CPUS, we'll get a mismatch between the ID that gets written into the FCH IOAPIC register and the ID in the corresponding ACPI table. In order to avoid that add defines to each SOC's southbridge.c and use them in all soc/amd code.

2020-07-20src: Make HAVE_CF9_RESET set the FADT reset registerAngel Pons
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as reset register in FADT. How unsurprising. We might as well use that information to automatically fill in the FADT accordingly. So, do it. To avoid having x86-specific code under arch-agnostic `acpi/`, create a new optional `arch_fill_fadt` function, and override it for x86 systems. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-07-20amd/{hudson,stoney,picasso}: Drop PM2 settings from FADTAngel Pons
The PM2_CNT register block is no longer needed, as explained in some comments. While they may have been copy-pasted around a lot, they are at least true for Hudson, and it makes sense to assume that they are true for newer chipsets as well. As per the ACPI specification, version 6.3, section 4.8.1.3 (PM2 Control Register): This register block is optional, if not supported its block pointer and length contain a value of zero. Since the FADT struct defaults to zero in coreboot, we don't need to do anything to indicate PM2_CNT is not supported. So, drop unneeded values.

If the PM1b_CNT_BLK is not supported, its pointer contains a value of zero in the FADT. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with PM1b for now.
