google/kukui: Revise FMAP layout for larger CBFS Kukui with vboot enabled will build with `detachable_ui`, which needs larger space in CBFS for more complicated assets. So we need to revise FMAP sections: - BOOTBLOCK (not really used) only needs <= 32K. - GBB can be much smaller since assets moved from GBB to CBFS. - FMAP is re-ordered (with the cost of less efficient in bsearch) so CBFS can get larger continuous space. - COREBOOT(CBFS) should take all space left. Since FMAP and COREBOOT have changed location, the system will need to reflash EC (which contains the new bootblock) as well.

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.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
