Hi,
These patches are adding basic support for RPi5. They are based on v2 series from Dmitry Malkin[1].
With them I am able to _start_ current openSUSE Tumbleweed without modification. They are still a lot of things to be added to the upstream Linux before it runs flawlessly on this device, but at least in U-Booot SD controller used for uSD card and Frameboffer and HDMI0 devices are working fine now. It seems that PCIe controller is working fine too, but I have not tested it too much.
Thank you very much for this work!
Serial console and reset are also functional.
I've applied the patchset to v2024.01-rc5 and built the rpi_arm64_defconfig target. I added enable_uart=1 and kernel=u-boot.bin to config.txt. While I see a brief U-Boot logo on HDMI, I haven't gotten anything on the serial console on pin 8/10 of the Raspberry Pi pin header. Is there anything specific needed to get the console going?

Hopefully this will help others add missing pieces more easily.
Happy hacking!
