2021-10-17soc/intel/skylake: switch to common ACPI codeMichael Niewöhner
Use the common ACPI code to reduce code duplication. After this change, `PSS_MAX_ENTRIES` is honored correctly in P-state table generation (as of commit c2540a9) and the number reduces from 10 to 7 entries. Also, remnants of P_BLK support missed in CB:58096 will vanish. Tested on google/fizz: no errors in dmesg, ACPI tables remain the same (except PSS, as mentioned above).

2021-10-17soc/intel/{common,apl,glk}: guard PM Timer option on SoCs w/o PM TimerMichael Niewöhner
Apollo Lake and Gemini Lake do not have a hardware PM ACPI timer but only uCode PM Timer emulation. Add a Kconfig `NO_PM_ACPI_TIMER` denoting SoCs without PM Timer and make it mutually exclusive with the Kconfig `USE_PM_ACPI_TIMER`. This is partly redundant to `PM_ACPI_TIMER_OPTIONAL`, which will be dropped in the follow-up change, though.

2021-10-17soc/intel: transition full control over PM Timer from FSP to corebootMichael Niewöhner
Set `EnableTcoTimer=1` in order to keep FSP from 1) enabling ACPI Timer emulation in uCode. 2) disabling the PM ACPI Timer. Both actions are now done in coreboot. `EnableTcoTimer=1` makes FSP skip these steps in any possible case including `SkipMpInit=0`, `SkipMpInit=1`, use of the MP PPI or FSP Multiphase Init. This way full control is left to coreboot.

Disable the PM ACPI timer during PMC init, when `USE_PM_ACPI_TIMER` is disabled. This is done to bring SKL, CNL, DNV in line with the other platforms, in order to transition handling of the PM timer from FSP to coreboot in the follow-up changes. For SKL and CNL, this temporarly redundantly disables the PM Timer, since FSP does that, too. This redundancy is resolved in the follow-up.

Since ACPI 5.0A it is allowed to disable the ACPI Timer, when the according FADT flag `ACPI_FADT_PLATFORM_CLOCK` is unset.

However, when the `TMR_STS` functionality is required, some legacy OSes might still not work (properly). Add a note about this to the Kconfig help.

The FADT contains a flag `ACPI_FADT_PLATFORM_CLOCK` telling the OSPM if a specification-compliant PM Timer is present. Currently, this flag is set regardless of the timer being enabled or disabled. To be specification-compliant, only set that flag, when the hardware PM Timer is enabled. This changes behaviour of all mainboards defaulting to USE_PM_ACPI_TIMER=n. Note: On platforms supporting uCode PM ACPI Timer emulation, this is required, too, because emulation does not support `TMR_STS`. Any OS or software checking this flag and thus relying on the overflow flag would not work (properly).

2021-10-15soc/amd/common/block/i2c: implement proper read_resourceFelix Held
Before this patch the reservation of the MMIO region of the I2C controllers was done in the LPC controller PCI device despite the I2C controllers already being devices in the devicetree. This patch implements this functionality as read_resources function of the I2C device instead. This will only reserve the memory when the I2C devices are enabled in devicetree which is a change from the previous behavior.

2021-10-15soc/intel/common/cse: Split CSE metadata into two CBFS filesFurquan Shaikh
This change splits CSE metadata structure (added to CBFS) into two separate CBFS files (me_rw.hash and me_rw.version). Since `struct cse_rw_metadata` is now used, it is dropped completely. This change is being made in order to prepare for the upcoming changes to stitch CSE binary at build time. Since the binary might not be available pre-built, it complicates the order of operations for the addition of CSE metadata structure and declaring hash and version as CPPFLAGS_common. Instead rules can be enabled for individual CBFS file targets for hash and version that ensure proper ordering as well.

`cse_fw_update()` is currently checking whether an update is required by comparing versions once and then again comparing versions later in `cse_is_downgrade_instance()` to determine if the update is an upgrade or downgrade. Additionally, if CSE RW partition is corrupt (determined based on `cse_is_rw_bp_sign_valid()`), `cse_is_downgrade_instance()` ends up using the corrupted version information to determine if it is a downgrade instance.

CSE_UPDATE_UPGRADE: Update required and it is an upgrade. 3. CSE_UPDATE_DOWNGRADE: Update required and it is a downgrade (requires data clear). 4. CSE_UPDATE_CORRUPTED: `cse_is_rw_bp_sign_valid()` failed and hence requires data clear. 5. CSE_UPDATE_METADATA_ERROR: Unable to read CSE metadata from CBFS.
