[MPC8272ADS]Problem adding flash partitions inside the device tree

[Jean-Michel Hautbois]

Hi everybody !
I am currently trying to add the support of partitions for the Flash chip on
my MPC8272ADS board (the chips are Sharp LH28F016SCT-L90).

I have added this part:

flash at 0,0 {
                        compatible = "jedec-flash";
                        reg = <0x0 0x0 0x2000000>;
                        bank-width = <4>;
                        device-width = <1>;

                        partition at ff800000 {
                                label = "kernel";
                                reg = <0xff800000 0x00400000>;
                                read-only;
                        };
                        partition at ffc00000 {
                                label = "user";
                                reg = <0xffc00000 0x00300000>;
                        };
                        partition at fff00000 {
                                label = "u-boot";
                                reg = <0xfff00000 0x00100000>;
                                read-only;
                        };
                };

But when I am compiling, I have these warnings:
Warning (reg_format): "reg" property in /localbus at f0010100/flash at 0

Can anyone help me ?
I can't understand what the "address-cells" is.

Thanks in advance !
Best Regards.
