"""Bintool implementation for fiptool
|
|
|
|
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.
|
|
|
|
Documentation is at:

|
|
|
usage: fiptool [--verbose] <command> [<args>]
|
|
Global options supported:
|
|
--verbose Enable verbose output for all commands.
|
|
|
|
Commands supported:
|
|
info List images contained in FIP.
|
|
create Create a new FIP with the given images.
|
|
update Update an existing FIP with the given images.
|
|
unpack Unpack images from FIP.
|
|
