| 10 | Provides common dependencies for Versatile Express platforms |
| 11 | based on Cortex-A5 and Cortex-A9 processors. In order to |
| 12 | build a working kernel, you must also enable relevant core |

| 34 | New Versatile Express platforms require Flattened Device Tree to |
| 35 | be passed to the kernel. |
| 36 | |
| 37 | This option enables support for systems using Cortex processor based |
| 38 | ARM core and logic (FPGA) tiles on the Versatile Express motherboard, |
| 39 | for example: |
| 40 | |
| 41 | - CoreTile Express A5x2 (V2P-CA5s) |
| 42 | - CoreTile Express A9x4 (V2P-CA9) |
| 43 | - CoreTile Express A15x2 (V2P-CA15) |
| 44 | - LogicTile Express 13MG (V2F-2XV6) with A5, A7, A9 or A15 SMMs |
| 45 | (Soft Macrocell Models) |
| 46 | - Versatile Express RTSMs (Models) |
| 47 | |
| 48 | You must boot using a Flattened Device Tree in order to use these |
| 49 | platforms. The traditional (ATAGs) boot method is not usable on |
| 50 | these boards with this option. |
| 51 | |
| 52 | If your bootloader supports Flattened Device Tree based booting, |
| 53 | say Y here. |
