[PATCH 0/8] Raspberry Pi 400/Compute Module 4 support

[Nicolas Saenz Julienne]

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. :)
