menu "Payload"
choice
prompt "Add a payload"
default PAYLOAD_NONE if !ARCH_X86
default PAYLOAD_SEABIOS if ARCH_X86
config PAYLOAD_NONE
bool "None"
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 'cbfstool'
to add a payload to the ROM image later.
config PAYLOAD_ELF
bool "An ELF executable payload"
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.
source "payloads/external/*/Kconfig.name"
endchoice
source "payloads/external/*/Kconfig"
config PAYLOAD_FILE
string "Payload path and filename"
depends on PAYLOAD_ELF
default "payload.elf"
help
The path and filename of the ELF executable file to use as payload.
# TODO: Defined if no payload? Breaks build?
config COMPRESSED_PAYLOAD_LZMA
bool "Use LZMA compression for payloads"
default y
depends on !PAYLOAD_NONE && !PAYLOAD_LINUX
help
In order to reduce the size payloads take up in the ROM chip
coreboot can compress them using the LZMA algorithm.
config PAYLOAD_OPTIONS
string
default ""
help
Additional cbfstool options for the payload
config PAYLOAD_IS_FLAT_BINARY
def_bool n
help
Add the payload to cbfs as a flat binary type instead of as an
elf payload
config COREINFO_SECONDARY_PAYLOAD
bool "Load coreinfo as a secondary payload"
default n
depends on ARCH_X86
help
coreinfo can be loaded as a secondary payload under SeaBIOS, GRUB,
or any other payload that can load additional payloads.
config MEMTEST_SECONDARY_PAYLOAD
bool "Load Memtest86+ as a secondary payload"
default n
depends on ARCH_X86 && !PAYLOAD_NONE
help
Memtest86+ can be loaded as a secondary payload under SeaBIOS, GRUB,
or any other payload that can load additional payloads.
