I really don't like setting the physical address this way, can we
not do this via the device tree?
At a high level I think we should add something like the following in
the .dts:
s...@fff00000 {
fsl,sram-ctrl-handle = <&L2>;
reg = <0xfff00000 0xNNNN>;
compatible = "fsl,mpc85xx-l2-sram";
}
the NNNN can be the size the sram is configured as.
