Installed a fresh Tumbleweed on a microSD card, booted it up with a rpi4 and after installing all necessary build tools I applied your patches to u-boot 2024.01 sources, and then executed these two commands to let it compile a u-boot.bin file which I then put in /boot/efi to replace the u-boot.bin which is/was already there. Then I pulled the SD card and moved it over to the RaspberryPi5 in trying to get it booted up. However, again no HDMI output at all and unfortunately also the serial output on the debug probe does not show U-boot popping up at all. Interestingly, using the patched u-boot.bin with a RaspberryPi4 still works and it boots up perfectly fine, but not with the RaspberryPi5 I have here.

This can be also of course the reason why it works for you while it doesn’t for me.

No problem. Here is the output of the RPI bootloader boot up until the system stalls:
