currently working on a project involving MPC8360 board, and was
handed a patch to the system .dts file that contained the following
snippet for the muram node:
muram@10000 {
- #address-cells = <1>;
+ #address-cells = <2>;
#size-cells = <1>;
compatible = "fsl,qe-muram", "fsl,cpm-muram";
- ranges = <0 0x10000 0xc000>;
+ ranges = <0 0 0x10000 0xc000>;
data-only@0 {
compatible =
"fsl,qe-muram-data","fsl,cpm-muram-data";
- reg = <0 0xc000>;
+ reg = <0 0x4000 0x4000>, <0 0x9400 0x1c00>;
};
};
i'm not a .dts file expert, but i'm baffled by the change in the
value of #address-cells. how does that make any sense? it seems to me
that that kind of change is a *really* fundamental change in the
specification of the underlying architecture.
can someone explain what that might mean? thanks.
