+ New Versatile Express platforms require Flattened Device Tree to
+ be passed to the kernel.
+
+ 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.
+
+ If your bootloader supports Flattened Device Tree based booting,
+ say Y here.
