Re: loading NOR flash from DT

I have here a MPC8544 DS board with NOR flash on it and Kumar's git
tree. I'm trying to detect this flash with the physmap_of module. I
added a nor_flash block (I used sequoia.dts as an example) into my
device tree on the same level as soc8544 or memory (or between them).
After modprobing physmap_of nothing happend. Then I tried to make a tree
with plb -> opb -> ebc and finally nor_flash but still nothing changed.

Is there a user space dependency or did I just edit my device tree the
wrong way? Any hints are welcome :)

Post your device tree please.  I don't recall MPC8544 even having PLB,
OPB, or EBC busses, so they likely aren't getting probed.

	flash@fc000000 {
			compatible = "amd,s29gl512n", "cfi-flash";
			reg = <fc000000 4000000>;
			bank-width = <2>;
			#address-cells = <1>;
			#size-cells = <1>;
			fs@0 {
					label = "fs";
					reg = <0 f80000>;
			};
			firmware@f80000 {
					label ="firmware";
					reg = <f80000 80000>;
					read-only;
			};

    This looks good, so the problem is it doesn't get registered by the 
platform code as I've said.
