I read in the freescale documentation "U-Boot for i.MX35 based Designs" 
that the i.MX35 3-stack board has 256MB SDRAM, but we can use only 128MB 
because the second chip select isn't configured. Depending on the 
circuit diagrams I think "CSD1" isn't configured.
I looked already in the datasheet of the cpu, but I couldn't found a 
solution for this problem.

Have anybody ever tried to enable this second chip select?
