Hi Wolfgang,

Of course the end result looks better. There is no doubt about that. But it has disadvantages, too. With the row of dots you can easily see how long you've been waiting - this visualizes variations in timing behaviour that may be indications for problems; also it clearly shows where we have to wait too long, i. e. where optimi- zations are needed.
I understand that the spinning wheel is not optimal for logfiles, but for the normal usage it just looks nicer for my taste. So I would prefer to stay with the spinning wheel, but if you decide that the 4xx DDR2 calibration mustn't use this, then let's apply your patch for the cpu/ppc4xx files.
It is my understanding that a rework of this code is under way which will avoid the long delay for the standard boot sequence (and only need it for board bringup or intentional recalibration).
Are you talking about storing the optimized autocalibration values in FLASH, as discussed on IRC some time ago? I don't know if somebody is working on this. I only know that AMCC is working on a fix for the autocalibration on Kilauea. Not sure if this effects the bootup time, I can only hope it does.
For this purpose, the row of dots is IMHO more useful than the spinning wheel.
Assuming my understanding is correct (is it?), then we could fix this now as well.
Again, if you decide that that's the way to go, then I will not object.
Best regards, Stefan
