This solves issues when larger amount of DRAM is used.
Shouldn't we check if we are using a "large amount of DRAM"?
If we don't check then even boards with small amount of RAM would have this additional delay.
I'm afraid this worked on boards with a small amound of RAM by sheer accident (or good will of the DRAM), time to play safe and fix this.
Can you please comment on why we are waiting and why we are waiting exactly this long? Can we maybe poll the needed time somehow?
We need to wait for the CPU clock to stabilize. I think there is a bit for that that we can poll, indeed. It's in my queue to revise the memory init code eventually actually, because I think I can make it even faster and fix some rough edges that are still there.
Thanks Detlev
