How about that?

	select ARCH_VEXPRESS_RS1
	help
	  This option enables support for systems using any of the following
	  ARM core tiles on the Versatile Express motherboard:

	  - CoreTile Express A5x2 (V2P-CA5s)
	  - CoreTile Express A9x4 (V2P-CA9)

	  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 you want your kernel to run on one of these platforms and your
	  bootloader supports Flattened Device Tree based booting, say Y.
