Do not use the same name as the non-LP GPIO config. This allows checking at build-time that a mainboard uses the correct GPIO config format. Without this commit, there are no build-time errors when using the wrong format of GPIO config, but there would be undefined behavior at runtime. Tested by trying to build asrock/b85m_pro4 and hp/folio_9480m after toggling the `INTEL_LYNXPOINT_LP` Kconfig option (and trimming down the USB config arrays for asrock/b85m_pro4). In both cases, building failed because the necessary GPIO config global is not defined, as expected.

For example acpigen_write_if() opens if-statement package, acpigen_write_if_end() closes it.

2021-02-26sb/intel/lynxpoint: Update LPT-H magic as per RC 1.9.1Angel Pons
Add the missing PM initialization for Lynxpoint-H. There are some small changes to Lynxpoint-LP, since some register writes are common among both PCH variants. This is based on version 1.9.1 of reference code. Remove the `pch_fixups()` function. The DMI configuration is specific to Lynxpoint-H. It is not valid for Lynxpoint-LP, which does not have DMI. Tested on Asrock B85M Pro4, still boots. Registers have the new values. Without this patch, nearly all registers don't have the expected values.

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.

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.
