| 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. |
