20 mainmenu "Coreboot Configuration"
27 This allows you to select certain advanced configuration options.
29 Warning: Only enable this option if you really know what you are
30 doing! You have been warned!
33 string "Local version string"
35 Append an extra string to the end of the coreboot version.
37 This can be useful if, for instance, you want to append the
38 respective board's hostname or some other identifying string to
39 the coreboot version number, so that you can easily distinguish
40 boot logs of different boards from each other.
43 string "CBFS prefix to use"
46 Select the prefix to all files put into the image. It's "fallback"
47 by default, "normal" is a common alternative.

179 This variable specifies whether a given board has a hard_reset
180 function, no matter if it's provided by board code or chipset code.
182 config BOARD_HAS_HARD_RESET
186 This variable specifies whether a given board has a reset.c
187 file containing a hard_reset() function.

202 This variable specifies whether a given board has a cmos.layout

248 #TODO Remove this option or make it useful.
249 config HAVE_LOW_TABLES
253 This Option is unused in the code. Since two boards try to set it to
254 'n', they may be broken. We either need to make the option useful or
255 get rid of it. The broken boards are:
259 config HAVE_HIGH_TABLES
263 This variable specifies whether a given northbridge has high table
265 It is set in northbridge/*/Kconfig.
266 Whether or not the high tables are actually written by coreboot is
267 configurable by the user via WRITE_HIGH_TABLES.
269 config HAVE_ACPI_TABLES
272 This variable specifies whether a given board has ACPI table support.
273 It is usually set in mainboard/*/Kconfig.
274 Whether or not the ACPI tables are actually generated by coreboot
275 is configurable by the user via GENERATE_ACPI_TABLES.
280 This variable specifies whether a given board has MP table support.
281 It is usually set in mainboard/*/Kconfig.
282 Whether or not the MP table is actually generated by coreboot
283 is configurable by the user via GENERATE_MP_TABLE.
285 config HAVE_PIRQ_TABLE
288 This variable specifies whether a given board has PIRQ table support.
289 It is usually set in mainboard/*/Kconfig.
290 Whether or not the PIRQ table is actually generated by coreboot
291 is configurable by the user via GENERATE_PIRQ_TABLE.
293 #These Options are here to avoid "undefined" warnings.
294 #The actual selection and help texts are in the following menu.

325 bool "Generate ACPI tables"
328 Generate ACPI tables for this board.
332 config GENERATE_MP_TABLE
333 depends on HAVE_MP_TABLE
334 bool "Generate an MP table"
337 Generate an MP table (conforming to the Intel MultiProcessor
338 specification 1.4) for this board.
342 config GENERATE_PIRQ_TABLE
343 depends on HAVE_PIRQ_TABLE
344 bool "Generate a PIRQ table"
347 Generate a PIRQ table for this board.
356 prompt "Add a payload"
362 Select this option if you want to create an "empty" coreboot
363 ROM image for a certain mainboard, i.e. a coreboot ROM image
364 which does not yet contain a payload.
366 For such an image to be useful, you have to use 'cbfstool'
367 to add a payload to the ROM image later.
370 bool "An ELF executable payload"
372 Select this option if you have a payload image (an ELF file)
373 which coreboot should run as soon as the basic hardware
374 initialization is completed.
376 You will be able to specify the location and file name of the
381 config FALLBACK_PAYLOAD_FILE
382 string "Payload path and filename"
383 depends on PAYLOAD_ELF
384 default "payload.elf"
386 The path and filename of the ELF executable file to use as payload.
388 # TODO: Defined if no payload? Breaks build?
389 config COMPRESSED_PAYLOAD_LZMA
390 bool "Use LZMA compression for payloads"
392 depends on PAYLOAD_ELF
394 In order to reduce the size payloads take up in the ROM chip
395 coreboot can compress them using the LZMA algorithm.
397 config COMPRESSED_PAYLOAD_NRV2B
406 bool "Add a VGA BIOS image"
408 Select this option if you have a VGA BIOS image that you would
409 like to add to your ROM.
411 You will be able to specify the location and file name of the
414 config FALLBACK_VGA_BIOS_FILE
415 string "VGA BIOS path and filename"
417 default "vgabios.bin"
419 The path and filename of the file to use as VGA BIOS.
421 config FALLBACK_VGA_BIOS_ID
422 string "VGA device PCI IDs"
426 The comma-separated PCI vendor and device ID that would associate
427 your VGA BIOS to your video card.
431 In the above example 1106 is the PCI vendor ID (in hex, but without
432 the "0x" prefix) and 3230 specifies the PCI device ID of the
433 video card (also in hex, without "0x" prefix).
439 # TODO: Better help text and detailed instructions.
441 bool "GDB debugging support"
444 If enabled, you will be able to set breakpoints for gdb debugging.
445 See src/arch/i386/lib/c_start.S for details.
