Binman bintool Documentation
|
|
============================
|
|
|
|
This file describes the bintools (binary tools) supported by binman. Bintools
|
|
are binman's name for external executables that it runs to generate or process
|
|
binaries. It is fairly easy to create new bintools. Just add a new file to the
|
|
'btool' directory. You can use existing bintools as examples.
|
|
|
|
|
|
|
|
Bintool: cbfstool: Coreboot filesystem (CBFS) tool
|
|
--------------------------------------------------
|
|
|
|
This bintool supports creating new CBFS images and adding files to an
|
|
existing image, i.e. the features needed by binman.
|
|
|
|
It also supports fetching a binary cbfstool, since building it from source
|
|
is fairly slow.
|
|
|
|
Documentation about CBFS is at https://www.coreboot.org/CBFS

Bintool: fiptool: Image generation for ARM Trusted Firmware
|
|
-----------------------------------------------------------
|
|
|
|
This bintool supports running `fiptool` with some basic parameters as
|
|
neeed by binman.
|
|
|
|
It also supports build fiptool from source.
|
|
|
|
fiptool provides a way to package firmware in an ARM Trusted Firmware
|
|
Firmware Image Package (ATF FIP) format. It is used with Trusted Firmware A,
|
|
for example.
|
|
|
|
See `TF-A FIP tool documentation`_ for more information.

Bintool: futility: Handles the 'futility' tool
|
|
----------------------------------------------
|
|
|
|
futility (flash utility) is a tool for working with Chromium OS flash
|
|
images. This Bintool implements just the features used by Binman, related to
|
|
GBB creation and firmware signing.
|
|
|
|
A binary version of the tool can be fetched.
|
|
|
|
See `Chromium OS vboot documentation`_ for more information.

Bintool: ifwitool: Handles the 'ifwitool' tool
|
|
----------------------------------------------
|
|
|
|
This bintool supports running `ifwitool` with some basic parameters as
|
|
neeed by binman. It includes creating a file from a FIT as well as adding,
|
|
replacing, deleting and extracting subparts.
|
|
|
|
The tool is built as part of U-Boot, but a binary version can be fetched if
|
|
required.
|
|
|
|
ifwitool provides a way to package firmware in an Intel Firmware Image
|
|
(IFWI) file on some Intel SoCs, e.g. Apolo Lake.
|
|
|
|
|
|
|
|
Bintool: lz4: Compression/decompression using the LZ4 algorithm
|
|
---------------------------------------------------------------
|
|
|
|
This bintool supports running `lz4` to compress and decompress data, as
|
|
used by binman.
|
|
|
|
It is also possible to fetch the tool, which uses `apt` to install it.
|
|
|
|
Documentation is available via::
|
|
|
|
man lz4
|
|
|
|
|
|
|
|
Bintool: lzma_alone: Compression/decompression using the LZMA algorithm
|
|
-----------------------------------------------------------------------
|
|
|
|
This bintool supports running `lzma_alone` to compress and decompress data,
|
|
as used by binman.
|
|
|
|
It is also possible to fetch the tool, which uses `apt` to install it.
|
|
|
|
Documentation is available via::
|
|
|
|
man lzma_alone
|
|
|
|
|
|
|
|
Bintool: mkimage: Image generation for U-Boot
|
|
---------------------------------------------
|
|
|
|
This bintool supports running `mkimage` with some basic parameters as
|
|
neeed by binman.
|
|
|
|
Normally binman uses the mkimage built by U-Boot. But when run outside the
|
|
U-Boot build system, binman can use the version installed in your system.
|
|
Support is provided for fetching this on Debian-like systems, using apt.
