- 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:
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.
