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