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.
