This tool is needed by some SoCs to sign the bootloader. See the list of supported SoCs: https://github.com/LibreELEC/amlogic-boot-fip The variable BR2_PACKAGE_HOST_AMLOGIC_BOOT_FIP_DEVICE is used to specify for which device this package needs to be used. This tool uses pre-compiled binaries in order to sign the bootloader. These binaries are provided under a proprietary license that prohibits any redistribution of the resulting images. A similar tool was tried to be added in the past: http://patchwork.ozlabs.org/project/buildroot/patch/1533545408-11248-2-git-send-email-narmstrong@baylibre.com/ This time however a license file is present which can be used by make legal-info. Additionally, acs_tool.pyc was replaced by acs_tool.py and is therefore not compiled anymore.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
