menu "General setup"
config EXPERIMENTAL
bool "Prompt for development and/or incomplete code/mainboards"
help
Enable this option if you want to test development features or
incomplete/unsupported mainboards.
We do not make any guarantees about anything that is marked
as EXPERIMENTAL! You have been warned!
config EXPERT
bool "Expert mode"
help
This allows you to select certain advanced configuration options.
It is mainly intended for coreboot developers.
Warning: Only enable this option if you really know what you're
doing! You have been warned!
config LOCALVERSION
string "Local version - append to coreboot release"
help
Append an extra string to the end of the coreboot version.
config OPTION_TABLE
bool "CMOS Option Table"
default y
help
This option is used to determine whether the mainboard has
a battery backed up real time clock with CMOS NVRAM, or if you want
to use it.
config BEEPS
bool "Enable beeps upon certain coreboot events"
depends EXPERT
default n
help
Enable this option to make coreboot beep upon certain events.
config WHOLE_PROGRAM_COMPILE
bool "Enable whole-program optimizations (DANGEROUS)"
depends EXPERT && EXPERIMENTAL
help
Enable 'gcc -fwhole-program -combine' for select code.
Needs lots of annotation in stage1 and stage2.
Works for initram only.
This increases compile time (no parallel compilation possible
anymore) and compiler memory usage (up to a factor of 20) and
makes debugging really hard.
Requires at least gcc 4.2.x, but miscompilations may occur.
Say No.
If you are a Gentoo user, say NO!

help
This option allows an unparsed ELF paylaod to be added and loaded.
choice
prompt "Payload type"
default PAYLOAD_NONE
config PAYLOAD_ELF
bool "An ELF executable payload file"
help
Select this option if you have a payload image (an ELF file)
which coreboot should run as soon as the basic hardware
initialization is completed.
You will be able to specify the location and file name of the
payload image later.
config PAYLOAD_NONE
bool "No payload"
help
Select this option if you want to create an "empty" coreboot
ROM image for a certain mainboard, i.e. a coreboot ROM image
which does not yet contain a payload.
For such an image to be useful, you have to use the 'lar' tool
to add a payload to the ROM image later.
endchoice
config PAYLOAD_FILE
string "Payload path and filename"
depends PAYLOAD_ELF
default "payload.elf"
help
The path and filename of the ELF executable file to use as payload.
config PAYLOAD_NO_PREPARSE_ELF
bool "Add ELF without parsing and converting to LAR entries"
depends PAYLOAD_ELF && PAYLOAD_ELF_LOADER
default n
help
Until now, coreboot has used ELF for the payload. There are many
problems with this, not least being the inefficiency -- the ELF has
to be decompressed to memory and then the segments have to be
copied. Plus, lar can't see the segments in the ELF -- to see all
segments, you have to extract the ELF and run readelf on it.
There are problems with collisions of the decompressed ELF
location in memory and the segment locations in memory.
Finally, validation of the ELF is done at run time, once you have
flashed the FLASH and rebooted the machine. Boot time is really
not the time you want to find out your ELF payload is broken.
Without this option, coreboot will direct lar to break each ELF
segment into a LAR entry. ELF will not be used at all. Note that
(for now) coreboot is not backward compatible -- if you put an ELF
payload in, coreboot can not parse it. We hope to remove ELF
entirely in the future.
config ZERO_AFTER_PAYLOAD
bool "Zero fill lar after adding the payload"
depends PAYLOAD_ELF
default n
help
This option speeds booting but makes it so that no further files may
be added to the lar.
