hi, i have two flashs, but my kernel can only find one , how can i write the dts?

this is my dts file:

flash@0,0 {
                        #address-cells = <1>;
                        #size-cells = <1>;
                        compatible = "cfi-flash";
                        probe-type = "CFI";
                        reg = <0 0 1000000>;
                        bank-width = <2>;
                        device-width = <1>;
                        hrcw@0 {
                                label = "hrcw";
                                reg = <0 40000>;
                        };
                        jffs@40000 {
                                label = "jffs";
                                reg = <40000 200000>;
                        };
                        jffs2@240000 {
                                label = "uimage";
                                reg = <240000 d80000>;
                        };
             };
flash@1,0 {
                        #address-cells = <1>;
                        #size-cells = <1>;
                        compatible = "cfi-flash";
                        probe-type = "CFI";
                        reg = <1000000 0 1000000>;
                        bank-width = <2>;
                        device-width = <1>;
                        jffs3@240000 {
                                label = "jffs2";
                                reg = <0 1000000>;
                        };
                };

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 { ... };

Ah, your dts file is in the old version 0 format. You must be on an older kernel, or at least haven't updated your dts file to the new format after upgrading.
