Raspberry Pi Compute Module 5 support

[Jojan]

 Sorry I mean 2712Raspebrry -P 4 , that the U-boot support as of now includes , bcm2711.dtsi
bcm2711-rpi-4-b.dts:#include "bcm2711.dtsi"

However RPi-5 uses broadcom 2712 chips.These dts files are not available in u-boot.Howver you can get it from other places and modify / inroduce in your device tree source and configure correctly.

 I've never heard of bcm7712, it's not

Or do you mean bcm2712?

I managed to get u-boot v2025.04 to load  by setting boot delay to -2,
same issue as described here:
https://lists.denx.de/pipermail/u-boot/2024-December/576043.html

What are the changes does the custodian version have that are needed?
It seems like it's not up to date with the new version u-boot.
