2020-03-24drivers/intel/gma/acpi: Reduce display switching stubsNico Huber
_DCS, _DGS and _DSS are required by specification. However, we never implemented them properly, and no OS driver com- plained yet. So we stub them out and keep the traditional behavior in case an OS driver checks for their existence. The old implementations also only returned static values as there never was any write to their GNVS variables. The TRAP() that was called in one place is actually implemented by some ThinkPad's SMI handler as docking event. However, as the call precedes these SMI handlers in coreboot history, it's most likely an accident.

2020-03-16mb/51nb/x210: correct battery ACPIMatt DeVillier
The X210 EC reports battery values in broken mAh. These have to be adjusted by 10000 * DGVO, as documented in https://github.com/torvalds/linux/blob/master/drivers/acpi/battery.c.

2020-03-16mb/51nb: Add support for the 51nb X210Matthew Garrett
The 51nb X210 is a replacement motherboard for Thinkpad X200/X201 systems, based on a modern Kabylake CPU. It also ships with no firmware protection, (IFD is fully unlocked, no protected regions are set, no Bootguard), making it an ideal coreboot target. This port is based on the support for the Skylake-based Purism Librem 13v3, with the following significant changes: * EC firmware is contained within the system SPI flash, and so a blob of EC firmware must be injected to a defined location during image build. * GPIO layout is different - this is currently just a raw import of the GPIO configuration from the vendor firmware * The system has two DIMMs, so an additional SPD address has been added * The USB port layout is different * The EC must be enabled at boot time through SuperIO-style logical device configuration * EC register layout is different, necessitating changes in the ACPI tables * The HDA pins are different * The genx_dec config is different All hardware appears to work as expected, although the SD reader is untested.
