mb/Kconfig: Add a prompt string for MAINBOARD_PART_NUMBER For some nissa variants, there are build configurations that need to use different blobs, but otherwise are identical. Currently, they use the same choice of board config and configure blob paths appropriately. This avoids duplication within the Kconfig file, but the resulting firmware images can be difficult to distinguish, since they report the same FRID. Add a prompt string for MAINBOARD_PART_NUMBER so it can be overridden and round-tripped through make oldconfig, allowing customisation of the reported FRID and other MAINBOARD_PART_NUMBER-derived values with minimal overhead. BUG=b:253966060 BRANCH=None TEST=CL:3960290 MAINBOARD_PART_NUMBER configs apply successfully Signed-off-by: Sam McNally <sammc@chromium.org> Change-Id: I3497d7fa1c04c8fa2592025c771d9dbc65632e6e Reviewed-on: https://review.coreboot.org/c/coreboot/+/68496 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Reka Norman <rekanorman@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.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
