Searching for U-Boot 1.1.6 and 1.2.0 for AmigaOne G3-SE, PCIe GFX testing

In the process of testing the machine with PCIe graphics card, and therefor in need of testing with different U-Boot versions. Also the stability of the machine is being worked on to be improved. Every SE and XE seems a bit unique in their errors/weakness, so to test it on the SE is of value.
Please let me know if you can share these versions of U-Boot for this over 20 years old developer pre-production system!

I have picked up that this is not commonly shared, as it was “beta”.
Keep in mind that the systems are by now anyhow very old, and also U-Boot is under the GPL, any addition or extension of it has to be shared, thus U-Boot for Amiga has to be shared, all versions, including source code.
Hope for some response!
