Also looked in the Eclipse license, it should be available too in a "reasonable manner".
In the readme there is the following:
This release contains as-yet-unreleased modifications to open source software
that are the property of Freescale Semiconductor Inc. All sources bound by the
GNU General Public License can be obtained by lodging a written request to
Freescale Semiconductor Inc.
But after multiple attempt to ask by email I just got nonsense responses.
These are legacy tools for legacy components.
Please make them public for research and to contribute to the open source community your tools are derivative of.
