I have now found the time to realize @bumerc idea. Thanks @Portisch for the u-boot files. But I compiled it myself (I wanted to do it anyway).
With the changed Mhz number booting worked at the first try! So again a big thank you to @Portisch and @bumerc, for your very useful help!
It works so far at first view everything. However, I noticed small things:
When I restart Coreelec, the box goes off, but not on again. Only after pressing the power button the box starts again (this was also the case with the original U-Boot).

If the box is off (after shutdown) and I want to start it with the remote control, it lights up shortly blue and nothing happens. Only with second pressing of the power key the box starts. In general not bad, because it didn’t work at all with the original u-boot!
