[U-Boot-Users] yet another how-to-configure-RAM-in-u-boot question

Hi there!

I'm having quite a few problems of understanding while trying to write 
an U-Boot configuration for my board.

I've read in the mailing list archives and in the README... as you see, 
it didn't help much.

The README says (I had the impression) that the following happens when 
the U-Boot starts:

U-Boot maps memory banks using the preliminary mapping, tests RAM sizes, 
then banks of the same are mapped from 0x0 on, starting with CS#2.

So my first question is: Am I in trouble for my SDRAM bank actually is 
at CS #1? This seems to be what U-Boot expects, everything in the README 
reads like no SDRAM should be at a bank below CS#2.
