Ashish,

You are enabling an SoC erratum, not a board erratum. It should be done in SoC
file. You may argue why there are ARM errata macros in this file already. I
think that was a mistake and should be moved out.

Since we don't have a config file for armv8, the closest one is
arch/arm/include/asm/arch-fsl-layerscape/config.h.
