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 at 0,1000000 { ... };
