U-Boot w/ Trusted Firmware Image Builder

This is a simple tool for build Arm firmware images from U-Boot, Trusted Firmware A, and the Linux devicetree repo. It uses the git 'repo' tool to clone a copy of each project and a Makefile to build for various Arm targets.

Using this tool

It is best to use this tool with the u-boot-manifest repo to fetch all the required source repositories. Use the git repo tool to fetch all the projects listed in the manifest and create the required symlinks. Install repo first. Most linux distros have repo packaged.

To initialize the build environment, create a new working directory and run the repo init command:

$ mkdir firmware-working
$ cd firmware-working
$ repo init -u https://github.com/glikely/u-boot-manifest
$ repo sync

This will clone all of the required git trees and link the Makefile into the root directory. To build the firmware, simply type:

$ make <target_name>_defconfig
$ make

Where <target_name> is a U-Boot defconfig that can be found in the u-boot/configs directory.

The QEMU config also provides a qemu target to run the image:

$ make qemu

Patches to target projects

There are a few changes to the main projects in the ./patches directory. You'll may need to apply those to get a working firmware image.

Supported Platforms

The following platforms should work out of the box. More to come as this tool matures.
