Peter, your explanation is fantastic ans exhaustive.

Only for this procedure you have to remove R159!

Or if you destroy the existing u-boot in Parallel Flash ;-)

I can definitely confirm, that u-boot-1.1.2 works fine in that case. If needed, I can send you the u-boot config.

Could you please send it to me ?

Hope, that helps a step further...

Yes, sometimes help and readme aren't clear enough for newbies ;-)
