progress:
I was able to get the commit for this RK3588 boot failure with "git bisect" maybe , many thanks.
https://github.com/u-boot/u-boot/…6149ce96a4d1037
This commit was merge commit, I will investigate more.
I was able to boot on my Orange Pi 5 Max with the u-boot v2025.10-rc1 that there were needed 8 commits revert.
But, I feel something strange. I'll take a short break. (I'll try chewitt u-boot 2025.10-rc4 version)
