util/cbfstool: Add a new mechanism to provide a memory map This replaces the mechanism with --ext-win-base --ext-win-size with a more generic mechanism where cbfstool can be provided with an arbitrary memory map. This will be useful for AMD platforms with flash sizes larger than 16M where only the lower 16M half gets memory mapped below 4G. Also on Intel system the IFD allows for a memory map where the "top of flash" != "below 4G". This is for instance the case by default on Intel APL. TEST: google/brya build for chromeos which used --ext-win-base remains the same after this change with BUILD_TIMELESS=1.

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.

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.
