Add custom DDR DRAM settings for the DHCOR and DHCOM SoMs and put them
into use by the board file instead of the default ones. These new DRAM
settings are a better fit for the SoMs.

Seems like quite a few of those stm32mp1 patches still aren't in

Yes,

I am preparing a pull request for this week or beginning of next week...

This patch will  be part of it.
