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