2023-08-08ACPI: Add helper fill_fadt_extended_pm_io()Kyösti Mälkki
Once platform code has filled in the (legacy) ACPI PM register map, added function will fill in the extended entries in FADT. TEST=samsung/lumpy and amd/mandolin FADT stays unchanged.

2023-04-29ACPI: Make FADT entries for RTC/CMOS architecturalKyösti Mälkki
For AMD, replace name RTC_ALT_CENTURY with RTC_CLK_ALTCENTURY that points to same offset. Since the century field inside RTC falls within the NVRAM space, and could interfere with OPTION_TABLE, it is now guarded with config USE_PC_CMOS_ALTCENTURY. There were no reference for the use of offset 0x48 for century.

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.

2020-07-20src: Drop useless PM1b settings from FADTAngel Pons
None of the currently-supported chips has PM1b_EVT nor PM1b_CNT event register blocks. According to the ACPI specification, version 6.3, sections 4.8.1.1 and 4.8.1.2 (PM1 Event/Control Registers): If the PM1b_EVT_BLK is not supported, its pointer contains a value of zero in the FADT. 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. So, drop unneeded writes to PM1b fields. 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.
