ec/chromeec/ec_smbios: Set system manufacturer for ChromeOS devices Currently, many Linux drivers use DMI quirks to identify ChromeOS devices and handle them accordingly: namely they look for the SMBIOS system manufactuer to be "GOOGLE" or "Google", and the bios-vendor to be coreboot. Historically this was consistently the case, but recent model ChromeOS devices allow the OEM to set the mainboard manufacturer, which is also the default system manufacturer. This breaks many DMI quirks, notably ones used by SOF (sound open firmware) for audio. To fix this, set the system manufactuer for ChromeOS devices to "Google" for devices selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID, leaving the OEM customization in place for the mainboard manufacturer. Since boards selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID are the only ones overriding the default mainboard manufacturer, they are the only ones which need this correction. Test: build/boot google/bloog with Linux 5.16, verify SOF drivers correctly detect device as a Chromebook and load the appropriate audio firmware.

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.

ANY_TOOLCHAIN
Kconfig option if you're feeling lucky (no support in this case).Optional:
make menuconfig
and make nconfig
)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.
