  	  This option enables support for systems using Cortex processor based
  	  ARM core and logic (FPGA) tiles on the Versatile Express motherboard,
  	  for example:
  
  	  - CoreTile Express A5x2 (V2P-CA5s)
  	  - CoreTile Express A9x4 (V2P-CA9)
  	  - CoreTile Express A15x2 (V2P-CA15)
  	  - LogicTile Express 13MG (V2F-2XV6) with A5, A7, A9 or A15 SMMs
  	    (Soft Macrocell Models)
  	  - Versatile Express RTSMs (Models)
  
  	  You must boot using a Flattened Device Tree in order to use these
  	  platforms. The traditional (ATAGs) boot method is not usable on
  	  these boards with this option.
