ec/lenovo/h8: Implement ACPI methods to set battery thresholds There are two known reverse-engineered ways to manage battery thresholds. This patch implements them and adds a way to enable them for different mainboards. Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11. Works fine with new Linux userspace API for controlling battery thresholds, available since 4.17. (/sys/class/power_supply/BAT0/charge_(start|stop)_threshold). The new API is supported by TLP (you might need to set NATACPI_ENABLE=1 in /etc/tlp.conf). tpacpi-bat works fine too.

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAINKconfig option if you're feeling lucky (no support in this case).
Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
