Thank you very much for this work!

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?
