2021-02-14sb,soc/amd: Move _PIC method to global scopeKyösti Mälkki
Fix regression with commit aa969e887a ACPI: Move PICM declaration. While mentioned in the commit message there already, the default value for AMD boards changed from IOAPIC mode to PIC mode. ACPI 6.3 spec has this text regarding _PIC method: If the platform CPU architecture supports PIC mode and the method is never called, the platform runtime firmware must assume PIC mode. If MADT has IOAPIC entries, OS will want to change to APIC model. But the method _PIC was not in the global scope so it could not be called and therefore _PRT continued to report PIC model interrupt routing. Already fixed for soc/amd/picasso in commit 839f668.

2021-02-07sb/intel/bd82x6x: Support ME Soft Temporary Disable ModeEvgeny Zinoviev
- Add support for ME Soft Temporary Disable Mode. In this mode, ME doesn't load its kernel and freezes at Bring UP (BUP) phase. This mode is saved in ME NVRAM (and thus will remain for next reboots and poweroffs). - Add support of new CMOS option for Sandy Bridge and Ivy Bridge ThinkPads. HOW TO USE To disable ME: 1. nvramtool -w me_state=Disabled 2. reboot To enable it back: 1. nvramtool -w me_state=Normal 2. reboot To check current status: intelmetool -m Tested on ThinkPad X230 and ThinkPad X220. BACKGROUND There's no Intel documentation that would explain how this should be implemented, in public. Working binary sequence for MKHI command to put ME in Soft Temporary Disable Mode, as well as a way to bring ME out of it (by writing to H_GS register), was found and published by researchers from PT Security: 1. To disable ME, BIOS issues the disable command (before End of Post) and reboots. ME is supposed to be disabled on the next boot after DID (DRAM Init Done). My numerous tests show that issuing the command and rebooting is not enough. If we reboot too early, ME will not be disabled. Apparently, it is doing something in background after receiving the command. It works with a delay of 500-1000 ms. I also tried to dump all known (documented) registers, such as GMES and HFS, before and during the next 2 seconds after execution of the disable command to find a possible indication that something's changed in ME and we're ready to reboot. Found nothing unfortunately. 2. To enable ME back, host writes value 0x20000000 to H_GS. PT slides don't contain any more information on it, but my tests show, that after writing this value, GMES[31:28] is changing from 0x01 (BUP phase) to 0x03 (Policy Module) to 0x06 (Host Communication). Then, after some more time, fw_init_complete bit of HFS becomes 1. This means that ME starts loading its kernel immediately, without reboot. On the other hand, Lenovo BIOS clearly perform a reboot after enabling it (one reboot after saving the settings, then ThinkPad logo appears, and then one more reboot). I'm assuming we have to reset too.

- Add Kconfig option to hide the Management Engine Interface device so the OS doesn't try to access it, if the Management Engine is in an inoperable mode, e.g. if me_cleaner is used. - Also hide the MEI if the ME is in Soft Temp Disable mode.

2021-02-06sb,soc/intel: Add wake source fields in GNVSKyösti Mälkki
For the moment, these are most not used but become a necessity for a unified <soc/nvs.h> approach. They would be required for the implementation of _SWS method for OSPM to determine the reason for system waking up. The related hardware registers are present with these platforms. It's expected that ACPI power-management related GNVS entries are grouped together to form a single struct in later works.
