config EXPERT
	bool "Expert mode"
	help
	  This allows you to select certain advanced configuration options.

	  Warning: Only enable this option if you really know what you are
	  doing! You have been warned!

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.

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 SCANBUILD_ENABLE
	bool "Build with scan-build for static code analysis"
	default n
	help
	  Changes the build process to use scan-build (a utility for
	  running the clang static code analyzer from the command line).

	  Requires the scan-build utility in your system $PATH.

	  For details see http://clang-analyzer.llvm.org/scan-build.html.

config SCANBUILD_REPORT_LOCATION
	string "Directory for the scan-build report(s)"
	default ""
	depends on SCANBUILD_ENABLE
	help
	  Directory where the scan-build reports should be stored in. The
	  reports are stored in subdirectories of the form 'yyyy-mm-dd-*'
	  in the specified directory.

	  If this setting is left empty, the coreboot top-level directory
	  will be used to store the report subdirectories.

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.

config SCONFIG_GENPARSER
	bool "Generate SCONFIG parser using flex and bison"
	default n
	depends on EXPERT
	help

	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 COMPRESS_RAMSTAGE
	bool "Compress ramstage with LZMA"
	default y
	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

config EARLY_CBMEM_INIT
	bool "Initialize CBMEM while in ROM stage"
	default n
	help
	  Make coreboot initialize the cbmem structures while running in ROM
	  stage. This could be useful when the ROM stage wants to communicate
	  some, for instance, execution timestamps.

config COLLECT_TIMESTAMPS
	bool "Create a table of timestamps collected during boot"
	depends on EARLY_CBMEM_INIT
	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 REQUIRES_BLOB
	bool
	default n
	help
	  This option can be configured by boards that require the blobs
	  repository for the default configuration. It will make the build
	  fail if USE_BLOBS is disabled. Users that still desire to do a
	  coreboot build for such a board can override this manually, but
	  this option serves as warning that it might fail.
