Hi Bin
I am trying to put the common part in a ae350.dtsi from ae350_32.dts
and ae350_64.dts.
But i encounter a problem as below :
smc node for 32 bit :
smc0: smc@e0400000 {
compatible = "andestech,atfsmc020";
reg = <0xe0400000 0x1000>;
};
smc node for 64 bit :
smc0: smc@e0400000 {
compatible = "andestech,atfsmc020";
reg = <0x0 0xe0400000 0x0 0x1000>;
};
Though they look like almost the same, but their reg is different.
Since can not put in a dtsi file for sharing.
Do you have any idea ?
