This series could be split into at least two or even three parts, but I kept it as is for now as it contains all the changes needed in order to have u-boot working on the new Raspberry Pi 400 and Raspberry Pi Compute Module 4.
There are core changes, specifically with regard to cpu to bus address space translations. So far we had relied on hardcoded values but RPi needs per device translations as it has at least three distinct bus address spaces with different offsets. So it's a good opportunity to implement bus tranlations the right way by parsing DT's dma-ranges.
I'm not that familiar with u-boot's device/driver model so I might have made some sille assumptions. Sorry in advance. :)
