Makefile.inc: Add bootblock to CBFS before others With CBFS verification, cbfstool (CB:41121) needs bootblock to be present in coreboot.pre in order to locate the metadata hash stored in it. Therefore we have to ensure that bootblock is added to CBFS before other CBFS files are added. To solve the problem, create the 'add_bootblock' function, and call it in the coreboot.pre recipe. Because bootblock.bin is now a prerequisite of coreboot.pre, it will get built even if CONFIG_BOOTBLOCK_IN_CBFS=n.

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.
