This change allows overriding the fdt slicer with a custom slicer, and uses this custom slicer to define the flash map on the RouterBoard RB800. D3305 converts the mpc85xx platform into a base class, so that systems based on the mpc85xx platform can add their own overrides. This change builds on D3305, and creates a RouterBoard (RB800) platform to initialize the slicer override.
