Ok. > Second, is the flash really part of the SoC? Not directly, it is attached to LocalPlus Bus Controller, which is part of the SoC. And the soc@ is currently the only recognized of bus for mpc5200, so if we want to move it to some other place new bindings will need to be defined for lpc (LocalPlus Controller) bus. But I am not quite sure where this should be attached. Bus is under LPC which is a part of the SoC, but on the other hand Soc address range covers only device control registers not the address space LPC may handle (that may be varied). Any ideas? m.
