These values reflect the base address and translation range of each
chip select.  How are your hardware chips selects configured.

If I assume that cs2 is configured for 0xc1000000 to 0xc100ffff, and
cs3 is configured for 0xc2000000 to 0xc203ffff, then your ranges
property would be:

                ranges = < 0 0 70000000 1000000  #my flash1
                           1 0 71000000 1000000  #my flash2
                           2 0 c1000000 10000
                           3 0 c2000000 40000 >;

If this is attached to chipselect #2, then this should be "reg = <2 0 20>;"
