This can be useful if, for instance, you want to append the respective board's hostname or some other identifying string to the coreboot version number, so that you can easily distinguish boot logs of different boards from each other. config CBFS_PREFIX string "CBFS prefix to use" default "fallback" help Select the prefix to all files put into the image. It's "fallback" by default, "normal" is a common alternative. config COMMON_CBFS_SPI_WRAPPER bool default n depends on SPI_FLASH depends on !ARCH_X86 help Use common wrapper to interface CBFS to SPI bootrom. config MULTIPLE_CBFS_INSTANCES bool "Multiple CBFS instances in the bootrom" default n help Account for the firmware image containing more than one CBFS instance. Locations of instances are known at build time and are communicated between coreboot stages to make sure the next stage is loaded from the appropriate instance. choice prompt "Compiler to use" default COMPILER_GCC help This option allows you to select the compiler used for building coreboot. config COMPILER_GCC bool "GCC" help Use the GNU Compiler Collection (GCC) to build coreboot. For details see http://gcc.gnu.org. config COMPILER_LLVM_CLANG bool "LLVM/clang" help Use LLVM/clang to build coreboot. For details see http://clang.llvm.org. endchoice config ANY_TOOLCHAIN bool "Allow building with any toolchain" default n depends on COMPILER_GCC help Many toolchains break when building coreboot since it uses quite unusual linker features. Unless developers explicitely request it, we'll have to assume that they use their distro compiler by mistake. Make sure that using patched compilers is a conscious decision. config CCACHE bool "Use ccache to speed up (re)compilation" default n help Enables the use of ccache for faster builds. Requires the ccache utility in your system $PATH. For details see https://ccache.samba.org. config FMD_GENPARSER bool "Generate flashmap descriptor parser using flex and bison" default n help Enable this option if you are working on the flashmap descriptor parser and made changes to fmd_scanner.l or fmd_parser.y. Otherwise, say N to use the provided pregenerated scanner/parser. config SCONFIG_GENPARSER bool "Generate SCONFIG parser using flex and bison" default n help Enable this option if you are working on the sconfig device tree parser and made changes to sconfig.l or sconfig.y. Otherwise, say N to use the provided pregenerated scanner/parser. config USE_OPTION_TABLE bool "Use CMOS for configuration values" default n depends on HAVE_OPTION_TABLE help Enable this option if coreboot shall read options from the "CMOS" NVRAM instead of using hard-coded values. config STATIC_OPTION_TABLE bool "Load default configuration values into CMOS on each boot" default n depends on USE_OPTION_TABLE help Enable this option to reset "CMOS" NVRAM values to default on every boot. Use this if you want the NVRAM configuration to never be modified from its default values. config UNCOMPRESSED_RAMSTAGE bool default n config COMPRESS_RAMSTAGE bool "Compress ramstage with LZMA" default y if !UNCOMPRESSED_RAMSTAGE default n help Compress ramstage to save memory in the flash image. Note that decompression might slow down booting if the boot flash is connected through a slow link (i.e. SPI). config INCLUDE_CONFIG_FILE bool "Include the coreboot .config file into the ROM image" default y help Include the .config file that was used to compile coreboot in the (CBFS) ROM image. This is useful if you want to know which options were used to build a specific coreboot.rom image. Saying Y here will increase the image size by 2-3KB. You can use the following command to easily list the options: grep -a CONFIG_ coreboot.rom Alternatively, you can also use cbfstool to print the image contents (including the raw 'config' item we're looking for). Example: $ cbfstool coreboot.rom print coreboot.rom: 4096 kB, bootblocksize 1008, romsize 4194304, offset 0x0 Alignment: 64 bytes Name Offset Type Size cmos_layout.bin 0x0 cmos layout 1159 fallback/romstage 0x4c0 stage 339756 fallback/ramstage 0x53440 stage 186664 fallback/payload 0x80dc0 payload 51526 config 0x8d740 raw 3324 (empty) 0x8e480 null 3610440 config EARLY_CBMEM_INIT def_bool !LATE_CBMEM_INIT config COLLECT_TIMESTAMPS bool "Create a table of timestamps collected during boot" default n help Make coreboot create a table of timer-ID/timer-value pairs to allow measuring time spent at different phases of the boot process. config HAS_PRECBMEM_TIMESTAMP_REGION bool "Timestamp region exists for pre-cbmem timestamps" default y if ARCH_ROMSTAGE_X86_32 && CACHE_AS_RAM help A separate region is maintained to allow storing of timestamps before cbmem comes up. This is useful for storing timestamps across different stage boundaries. config USE_BLOBS bool "Allow use of binary-only repository" default n help This draws in the blobs repository, which contains binary files that might be required for some chipsets or boards. This flag ensures that a "Free" option remains available for users. config COVERAGE bool "Code coverage support" depends on COMPILER_GCC default n help Add code coverage support for coreboot. This will store code coverage information in CBMEM for extraction from user space.

Those modules can be loaded anywhere and all the relocations are handled automatically. config RELOCATABLE_RAMSTAGE depends on EARLY_CBMEM_INIT bool "Build the ramstage to be relocatable in 32-bit address space." default n select RELOCATABLE_MODULES help The reloctable ramstage support allows for the ramstage to be built as a relocatable module. The stage loader can identify a place out of the OS way so that copying memory is unnecessary during an S3 wake. When selecting this option the romstage is responsible for determing a stack location to use for loading the ramstage. config CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM depends on RELOCATABLE_RAMSTAGE bool "Cache the relocated ramstage outside of cbmem." default n help The relocated ramstage is saved in an area specified by the by the board and/or chipset. config FLASHMAP_OFFSET hex "Flash Map Offset" default 0x00670000 if NORTHBRIDGE_INTEL_SANDYBRIDGE_MRC default 0x00610000 if NORTHBRIDGE_INTEL_IVYBRIDGE_MRC default CBFS_SIZE if !ARCH_X86 default 0 help Offset of flash map in firmware image # TODO: This doesn't belong here, move to src/arch/x86/Kconfig choice prompt "Bootblock behaviour" default BOOTBLOCK_SIMPLE config BOOTBLOCK_SIMPLE bool "Always load fallback" config BOOTBLOCK_NORMAL bool "Switch to normal if CMOS says so" endchoice # To be selected by arch, SoC or mainboard if it does not want use the normal # src/lib/bootblock.c#main() C entry point. config BOOTBLOCK_CUSTOM bool default n config BOOTBLOCK_SOURCE string default "bootblock_simple.c" if BOOTBLOCK_SIMPLE default "bootblock_normal.c" if BOOTBLOCK_NORMAL config SKIP_MAX_REBOOT_CNT_CLEAR bool "Do not clear reboot count after successful boot" default n depends on BOOTBLOCK_NORMAL help Do not clear the reboot count immediately after successful boot. Set to allow the payload to control normal/fallback image recovery. Note that it is the responsibility of the payload to reset the normal boot bit to 1 after each successsful boot. config UPDATE_IMAGE bool "Update existing coreboot.rom image" default n help If this option is enabled, no new coreboot.rom file is created. Instead it is expected that there already is a suitable file for further processing. The bootblock will not be modified. config GENERIC_GPIO_LIB bool default n help If enabled, compile the generic GPIO library. A "generic" GPIO implies configurability usually found on SoCs, particularly the ability to control internal pull resistors. config BOARD_ID_AUTO bool default n help Mainboards that can read a board ID from the hardware straps (ie. GPIO) select this configuration option. config BOARD_ID_MANUAL bool default n depends on !BOARD_ID_AUTO help If you want to maintain a board ID, but the hardware does not have straps to automatically determine the ID, you can say Y here and add a file named 'board_id' to CBFS. If you don't know what this is about, say N. config BOARD_ID_STRING string "Board ID" default "(none)" depends on BOARD_ID_MANUAL help This string is placed in the 'board_id' CBFS file for indicating board type. config RAM_CODE_SUPPORT bool default n help If enabled, coreboot discovers RAM configuration (value obtained by reading board straps) and stores it in coreboot table. config BOOTSPLASH_IMAGE bool "Add a bootsplash image" help Select this option if you have a bootsplash image that you would like to add to your ROM. This will only add the image to the ROM. To actually run it check options under 'Display' section. config BOOTSPLASH_FILE string "Bootsplash path and filename" depends on BOOTSPLASH_IMAGE default "bootsplash.jpg" help The path and filename of the file to use as graphical bootsplash screen.
