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.

choice
	prompt "Compiler to use"
	default COMPILER_GCC
	help
	  This option allows you to select the compiler used for building
	  coreboot.
	  You must build the coreboot crosscompiler for the board that you
	  have selected.

	  To build all the GCC crosscompilers (takes a LONG time), run:
	    make crossgcc

	  For help on individual architectures, run the command:
	    make help_toolchain

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 (TESTING ONLY - Not currently working)"
	help
	  Use LLVM/clang to build coreboot.  To use this, you must build the
	  coreboot version of the clang compiler.  Run the command
	    make clang
	  Note that this option is not currently working correctly and should
	  really only be selected if you're trying to work on getting clang
	  operational.

	  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 COMPRESS_PRERAM_STAGES
	bool "Compress romstage and verstage with LZ4"
	depends on !ARCH_X86
	default y
	help
	  Compress romstage and (if it exists) verstage with LZ4 to save flash
	  space and speed up boot, since the time for reading the image from SPI
	  (and in the vboot case verifying it) is usually much greater than the
	  time spent decompressing. Doesn't work for XIP stages (assume all
	  ARCH_X86 for now) for obvious reasons.

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

	default n
	help
	  Enable display of CBMEM during romstage and postcar.

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 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 "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

config NO_STAGE_CACHE
