utils: Add initial version of "remove_unused_code" script This script creates a patch to remove all of the coreboot code that a platform doesn't use. This is useful for auditing the codebase for an individual platform or releasing a platform's code. Unlike the script that Sage used that did something similar, this keeps the entire Kconfig tree (Though in a single file), all makefiles that are required to build, and the standard build tools can still be used. This will allow for much easier re-integration back into the coreboot codebase if code is released after running this. This is just the initial version and more features needed to be added to make it fully functional. - It should be able to build multiple configurations to retain the code for all of those configurations. - Flag to remove submodules files as well - Additional variable flags to replace hardcoded values. - The list of makefiles that need to be kept is pretty long, and could be updated so that they aren't needed by the top level makefiles. - Add flag to show changed files - Show number of files before and after script is run Signed-off-by: Martin Roth <gaumless@gmail.com> Change-Id: Iec69db2ad1358846d649db627b6d60ac8c2204e4 Reviewed-on: https://review.coreboot.org/c/coreboot/+/59169 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Raul Rangel <rrangel@chromium.org>
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_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.
