	  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.
