25	  ARM core and logic (FPGA) tiles on the Versatile Express motherboard,
26	  for example:
27
28	  - CoreTile Express A5x2 (V2P-CA5s)
29	  - CoreTile Express A9x4 (V2P-CA9)
30	  - CoreTile Express A15x2 (V2P-CA15)

32	    (Soft Macrocell Models)
33	  - Versatile Express RTSMs (Models)
34
35	  You must boot using a Flattened Device Tree in order to use these
36	  platforms. The traditional (ATAGs) boot method is not usable on
37	  these boards with this option.
