This looks wrong.  If you're second flash is on chip select 1 as the

node name suggests, then this should be (first cell is CS#, second is

offset, and third is size.  Alos you're missing the 0x prefix):

reg = <1 0 0x1000000>;

If your second flash is on chip select 0 with the first flash, but

offset by 0x1000000, then reg should be:

reg = <0 0x1000000 0x1000000>;

and the name should be:

flash@0,1000000 { ... };
