I actually just did that. 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. 

Any idea why this might be the case here while you report that the above mentioned procedure works for you? In fact, the RaspberryPi5 I have here is a 8GB model and with the rpi-eeprom version from 2024/01/05 [1] in case this might be relevant.

Best Regards,

Jens
