mb/lenovo/*: Add support for VBOOT on 12MiB devices Enable VBOOT support on all devices that have a 12 MiB flash, using RW_MAIN_A + RW_MAIN_B partition, allowing the use of tianocore payload in both RW_MAIN_A, RW_MAIN_B and WP_RO. * Add VBNV section to cmos.layout * Add FMAP for VBOOT * Select Kconfigs for VBOOT * Enable VBOOT_SLOTS_RW_AB by default The VBNV is intentionally not covered by the CMOS checksum. Tested on x230 and T440p.

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:
