2020-07-20src: Report word-sized access for PM1a_EVTAngel Pons
According to the ACPI specification, version 6.3: Accesses to the PM1 status registers are done through byte or word accesses. The same is said about the PM1 Enable registers. Therefore, reporting dword-sized access is wrong and means nothing anyway. Since some other platforms use word-sized access, use word everywhere for consistency. 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: 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.

They are ignored if the ACPI_FADT_WBINVD flag is set, which is required on current ACPI versions and only maintained for ACPI 1.0 compatibility.

2020-07-20src: Never overwrite `fadt->flags`Angel Pons
Instead, just flip the desired bits using bitwise operations. As this is initially zero, the resulting value is the same. This allows flags to be set from anywhere regardless of execution order.

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.

2020-07-20src: Drop useless GPE1 settings from FADTAngel Pons
None of the currently-supported chips has a GPE1 block. The ACPI spec, version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says: If a generic register block is not supported then its respective block pointer and block length values in the FADT table contain zeros. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with GPE1 for now. So, drop the unneeded writes to GPE1 fields.

2020-06-10sb/intel, ACPI: Do not override FADT preferred_pm_profileKyösti Mälkki
Setting preferred_pm_profile under sb/ overrides the default determined from SYSTEM_TYPE_xx (or possibly SMBIOS_ENCLOSURE_TYPE with followup work). This is not desireable. Boards need to either select a pre-defined SYSTEM_TYPE_xx or provide board-specific mainboard_fill_fadt() should they need to change this. As they already select SYSTEM_TYPE_LAPTOP, following boards will maintain PM_MOBILE: lenovo/t400 lenovo/x200 roda/rk9 Following will change to PM_DESKTOP: aopen/dxplplusu asus/p2b emulation/qemu-i440fx emulation/qemu-q35 Change-Id: I2986eb0a8abc94507e9797cc8b64611ae4bd888a Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42186 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>
