So, we're at -rc2 for v2020.07.  The DDR calculation stuff I can see
getting pulled in.  Is the ethernet driver for this SoC so far from done
that it's not ready for linux-next?  Things don't have to be in mainline
proper, but the expectation is that it's making reasonable progress
there and been reviewed so that binding changes between what we take in
U-Boot at first and a final re-sync once it is in mainline are minimal.
