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?
Welcome to the club! :)
The RPi5 uses a rather non-standard port for debug console:

Up to now I wasn't able to get serial console on the normal pins 8/10.

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