				3	Binman bintool Documentation
				4	============================
				5
				6	This file describes the bintools (binary tools) supported by binman. Bintools
				7	are binman's name for external executables that it runs to generate or process
				8	binaries. It is fairly easy to create new bintools. Just add a new file to the
				9	'btool' directory. You can use existing bintools as examples.

				13	Bintool: cbfstool: Coreboot filesystem (CBFS) tool
				14	--------------------------------------------------
				15
				16	This bintool supports creating new CBFS images and adding files to an
				17	existing image, i.e. the features needed by binman.
				18
				19	It also supports fetching a binary cbfstool, since building it from source
				20	is fairly slow.
				21
				22	Documentation about CBFS is at https://www.coreboot.org/CBFS

				26	Bintool: fiptool: Image generation for ARM Trusted Firmware
				27	-----------------------------------------------------------
				28
				29	This bintool supports running `fiptool` with some basic parameters as
				30	neeed by binman.
				31
				32	It also supports build fiptool from source.
				33
				34	fiptool provides a way to package firmware in an ARM Trusted Firmware
				35	Firmware Image Package (ATF FIP) format. It is used with Trusted Firmware A,
				36	for example.
				37
				38	See `TF-A FIP tool documentation`_ for more information.

				45	Bintool: futility: Handles the 'futility' tool
				46	----------------------------------------------
				47
				48	futility (flash utility) is a tool for working with Chromium OS flash
				49	images. This Bintool implements just the features used by Binman, related to
				50	GBB creation and firmware signing.
				51
				52	A binary version of the tool can be fetched.
				53
				54	See `Chromium OS vboot documentation`_ for more information.

				61	Bintool: ifwitool: Handles the 'ifwitool' tool
				62	----------------------------------------------
				63
				64	This bintool supports running `ifwitool` with some basic parameters as
				65	neeed by binman. It includes creating a file from a FIT as well as adding,
				66	replacing, deleting and extracting subparts.
				67
				68	The tool is built as part of U-Boot, but a binary version can be fetched if
				69	required.
				70
				71	ifwitool provides a way to package firmware in an Intel Firmware Image
				72	(IFWI) file on some Intel SoCs, e.g. Apolo Lake.
				73
				74
				75
				76	Bintool: lz4: Compression/decompression using the LZ4 algorithm
				77	---------------------------------------------------------------
				78
				79	This bintool supports running `lz4` to compress and decompress data, as
				80	used by binman.
				81
				82	It is also possible to fetch the tool, which uses `apt` to install it.
				83
				84	Documentation is available via::
				85
				86	man lz4
				87
				88
				89
				90	Bintool: lzma_alone: Compression/decompression using the LZMA algorithm
				91	-----------------------------------------------------------------------
				92
				93	This bintool supports running `lzma_alone` to compress and decompress data,
				94	as used by binman.
				95
				96	It is also possible to fetch the tool, which uses `apt` to install it.
				97
				98	Documentation is available via::
				99
				100	man lzma_alone
				101
				102
				103
				104	Bintool: mkimage: Image generation for U-Boot
				105	---------------------------------------------
				106
				107	This bintool supports running `mkimage` with some basic parameters as
				108	neeed by binman.
				109
				110	Normally binman uses the mkimage built by U-Boot. But when run outside the
				111	U-Boot build system, binman can use the version installed in your system.
				112	Support is provided for fetching this on Debian-like systems, using apt.
