Could you please quickly elaborate on your test environment and the test config.txt for the RaspberryPi5? Here I have compiled U-Boot 2024.01 with your patches applied and using the „rpi_arm64_defconfig“, put the u-boot.bin file on the sd card and then added „kernel=u-boot.bin“ to the config.txt file. The environment I am using is a buildroot-based system which boots nicely with the default RaspberryPi boot loader and a RaspberryPi5. However, as soon as I replace the „kernel=Image“ line with „kernel=u-boot.bin“ the system stalls and there is no HDMI output (nor any console output) with the u-boot 2024.01 version and your patches applied.

Yes, I am using rpi_arm64_defconfig for building the U-Boot.
And as I wrote in the cover letter I am using openSUSE Tumbleweed
image[1], [2]. Once you copy image to uSD card mount EFI uSD
partition and copy new u-boot.bin over existing one. That
it is. Just make sure you clearly sync, unmount the card.
You can find config.txt file in the EFI partition.

Ivan
