config LOCALVERSION
string "Local version string"
help
Append an extra string to the end of the coreboot version.
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

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
depends on COLLECT_TIMESTAMPS
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.
If unsure, say N.
config RELOCATABLE_MODULES
bool
default n
help
If RELOCATABLE_MODULES is selected then support is enabled for
building relocatable modules in the RAM stage. 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.

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"

like to add to your ROM.
This will only add the image to the ROM. To actually run it check
options under 'Display' section.

of the ROM (passed through cbfstool -s) everywhere else. It defaults
to span the whole ROM on all but Intel systems that use an Intel Firmware

components like ChromeOS's vboot/FMAP or Intel's IFD / ME / TXE
binaries.

# mutually exclusive. One of these options must be selected in the

# the power button. Chipset code uses the ENABLE_POWER_BUTTON option set
# in mainboard/Kconfig to know if the button should be enabled or not.
