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