   12 description: The Integrator/AP is a prototyping platform and as such has a
   13   site for stacking up to four logic modules (LM) designed specifically for
   14   use with this platform. A special system controller register can be read to
   15   determine if a logic module is connected at index 0, 1, 2 or 3. The logic
   16   module connector is described in this binding. The logic modules per se
   17   then have their own specific per-module bindings and they will be described
   18   as subnodes under this logic module extension bus.

   36     description: Nodes on the Logic Module bus represent logic modules
   37       and are named with bus. The first module is at 0xc0000000, the second
   38       at 0xd0000000 and so on until the top of the memory of the system at
   39       0xffffffff. All information about the memory used by the module is
   40       in ranges and dma-ranges.
