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.

Select this option if you have a payload image (a FIT 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.

Choose the compression algorithm for the chosen payloads.
You can choose between None, LZMA, or LZ4.
config COMPRESSED_PAYLOAD_NONE
bool "Use no compression for payloads"
help
Do not compress the payload.
config COMPRESSED_PAYLOAD_LZMA

help
In order to reduce the size payloads take up in the ROM chip
coreboot can compress them using the LZMA algorithm.

help
In order to reduce the size payloads take up in the ROM chip
coreboot can compress them using the LZ4 algorithm.

Select this option if your payload is of type FIT.
Enables FIT parser and devicetree patching. The FIT is non
self-extracting and needs to have a compatible compression format.
